A stretched leg, “pop”! curled up, “clicked”! stretched legs + curled legs =? “Papa, papa, papa, duo Lai Mifa…” Why is my knee still playing symphony? Doctor, I can’t stop my knee rhythm music at all, what should I do! Doctor: The abnormal sound of the knee joint, also called “knee snapping”, is the sound and sound of the surrounding tendon sliding or joint impact when the knee joint is flexed and extended. Vibration, such as the sound of the popliteal muscle sliding on the outside of the knee joint. Knee snapping is divided into two types: Physiological: harmless, generally only occurs when the joint is suddenly stretched or flexed, the sound is crisp, single, non-repetitive, not accompanied by pain or discomfort, and does not affect the movement of the knee joint. Sometimes there is a sense of relaxation after the buzzer. Pathological: Once the snapping sound is accompanied by joint pain, jamming, and there will be limited movement and joint swelling after the sound. This pathological snapping may indicate changes in some parts of the joint. For physiological snapping, we don’t need to worry too much. We should warm up before the activity and slow down the speed of joint flexion to adjust. However, the pathological buzzer needs to go to the hospital as soon as possible to avoid deterioration of the condition. What causes knee snapping? 01 meniscus injury 02 discoid meniscus 03 knee joint patellofemoral joint impact 04 knee joint friction around the tendon 05 knee synovial fold syndrome 06 joint capsule ligament proliferation 07 osteoarthritis 08 Loose knee joint 09 Cruciate ligament old injury 10 others.
Knee degradation, these four words, should be something that many friends with knee problems are more worried about. Even some young people in their twenties and thirties are beginning to wonder if their joints have degenerated prematurely. Experts from the Symptoms Gout and Rheumatism Hospital came to share with you today. Four naked eyes can see the signs of severe knee degradation. If not, you can rest assured. Situation 1: Going upstairs and downstairs arthralgia This situation mostly occurs in middle-aged people after the age of 30. It is manifested as knee joint pain when going up and downstairs. When our human body is going up and downstairs, the knee joints can bear the greatest capacity. At this time, the knee joints are completely in a tight state and also in a completely worn state. If the knee joint pain occurs during the going up and downstairs, It may be caused by the degeneration of the knee joint. The degeneration of the knee joint will weaken the cartilage protection of our joints, and the lubrication of the joint fluid will be reduced, which will cause pain. This is generally an early phenomenon of knee joint degeneration. In the late stage, there will be pain not only to go up and down, but also to walk. Case 2: Pain during squatting. Squatting is the same as going up and down stairs. It is also an action with severe stress on the knee joint. If the knee joint is healthy, squatting will not cause any burden on the knee joint because it has cartilage protection on the joint surface. , There is also synovial fluid as a lubricant, so there will be no feeling, and if we squat, joint pain will be a sign of knee joint degradation. When we squat, we put all the neutrality of the body on the feet and knees in order to maintain balance. At this time, the knees will wear out in order to maintain balance. If the knee joints are not good or have other diseases, they will be painful. . Situation 3: It hurts when you press it. If you don’t press it, it hurts. To judge whether the knee joint is aging, we can also judge by pressing. If the knee joint is aging, swelling will appear, and pain will appear by pressing. Our knee joints have relatively few muscles and tissues, and the edema is not particularly obvious, so we can judge whether the knee joint is aging by pressing. If there is pain during the pressing process, it may be caused by edema. At this time, our knee joint is very fragile, because only when the cartilage protective layer on the knee joint surface degenerates, edema will appear. Situation 4: Restricted movement and inflexible knee joint Many patients with knee joint degeneration will have restricted movement. This is because our knee joints are not as flexible as they used to be in the process of wear and tear. Some people will appear. Can’t fully straighten, or legs can’t be stretched straight during stretching, can only bend. Others may not be able to bounce, or the steps may become very small, and they may not be able to walk in large strides. This is all due to knee degeneration and knee inflexibility. It usually occurs in middle-aged and elderly people after the age of 50, and there will be many other joint diseases, such as arthritis.
Everyone must have heard that “the roots of a tree die first, and the legs of a man die first”. If you compare the body to a machine, the “legs” are the motors that provide power. If the motor fails, the machine will age and run poorly. Many people sometimes suffer from leg pain, especially knee joint pain. The first reaction of many people is bone hyperplasia, so various remedies for the treatment of bone hyperplasia began to be used, and the wrong treatment was started for unknown reasons. . Not to mention that it generally ends up ineffective. More importantly, it may confuse bone hyperplasia and rheumatoid arthritis, which can cause misdiagnosis. Rheumatoid arthritis is a very troublesome immune disease, and misdiagnosis will only worsen. Condition. Several major symptoms of knee bone hyperplasia Bone spurs are commonly referred to as “bone hyperplasia”, which is a natural phenomenon of the human body. The bone spurs themselves do not cause pain. The pain is caused by the congestion and blood pressure next to the bone spurs and the nerves. . It is mainly due to excessive use and improper use of joints, resulting in excessive wear of bones and soft tissues. Bone hyperplasia can happen to everyone, and it is very harmful. So what are the more common knee symptoms? 01 The main symptom is joint pain, which is mainly manifested from mild to severe. In the early stage of the disease, patients often experience joint pain during activities, most notably when going up and down the stairs, and the pain can get better after rest. However, as time goes by, pain can also appear during rest, and the pain worsens after overactivity. 02 Generally, patients suffering from knee bone hyperplasia will feel friction noise in their knees in daily life, especially when going upstairs and downstairs, or when standing and turning around, the pain is most obvious. In addition, there will be tenderness around the patella or joint space. 03 If the patient does not pay attention to it in the early stage of the illness, it will lead to aggravation of the disease, and may have mobility problems, which will cause joint instability and inconvenience. In severe cases, the knee joint will suddenly stay in a certain position. Bounce. This shows that there has been bone hyperplasia in the joints. Knee rheumatism can be accompanied by other joint abnormalities. Rheumatoid in the knee joint can cause joint swelling. At the same time, it also affects the mandibular joint, causing redness, swelling and tenderness. At this time, there is no cervical spine hyperostosis. The shoulder is also susceptible to rheumatoid arthritis. It is often caused by upper arm pain at night, difficulty in raising the arm, stiffness of the arm, and inability to move normally. At the same time, nodules may appear at the elbow joint. About 80% of patients will experience fatigue symptoms caused by anemia, because the amount of oxygen-carrying hemoglobin in the blood drops. If it is just bone hyperplasia, it is impossible to cause fatigue. Flexion contracture of both knee joints is very common in rheumatoid arthritis. When the flexion deformity exceeds 30°, the patient usually has to rely on a wheelchair to live. Different patients may have different knee symptoms. If the above conditions occur, you need to go to the hospital for a detailed examination to confirm whether it is rheumatoid arthritis, and cooperate with the doctor for symptomatic treatment based on the relevant symptoms.
If the human body is a building, then the bones are the reinforced concrete supporting the building. If the bones are not strong, the building must be unstable! The degree of bone firmness is related to nutrition. Now our nutrition is very good, and we can eat whatever we want. No matter how good you eat, no matter how hard you exercise, if you don’t avoid injury or damage to your bones, everything will be in vain~ 1. Knee damage-squatting to choose vegetables, washing, squatting, washing clothes, choosing vegetables, wiping the floor These are the habits we are most familiar with. But this is dangerous! Research calculations show that the weight of the knee is zero when lying flat, the weight when standing up and walking is 1 to 2 times the weight, running is 4 times, and squatting and kneeling are 8 times! Clinically, there are usually more women with knee disease than men, which is also related to this. Elderly and obese people (BMI≥25) try not to squat or reduce the squat time, preferably not more than 20 minutes. If the elderly squat or get up, it is best to hold a table or chair, which can reduce the pressure on the knee joint and reduce the loss. 2. Destroy the spine-carrying a shoulder bag A shoulder bag is very convenient, and young friends also find a shoulder bag beautiful and fashionable. Careful friends will find that people who often carry a single-shoulder backpack are prone to shoulder pain, even high and low shoulders. This is because, in order to prevent the strap from sliding down, one shoulder is always used to push up and push inward. If this is the case for a long time, the spine may also bend, and women may even have breast asymmetry. Especially students in the stage of bone growth and development are more susceptible. For students in school, it is best to carry a backpack. If you are an adult, it’s best to have your shoulders alternate. 3. Destroy the lumbar spine-nesting in the sofa, lying on the sofa, watching TV on the bed, reading the newspaper, playing on the phone, it is very pleasant to watch, but this is a kind of destruction to the lumbar spine! In the semi-recumbent position, the lumbar spine lacks sufficient support, the original curvature is forced to change, and the gravity on the intervertebral disc increases, which may cause muscle strain and scoliosis over time. Want to sit more comfortably? It is also possible to change the posture. When half-lying, put a pillow behind the waist to support the lumbar spine, so that it will not put too much pressure on the lumbar spine. 4. Destroy the cervical spine-the action of lowering your head to play with your mobile phone can now be seen everywhere, on the bus, on the subway, at home… But this action is a disaster for the cervical spine! When using a mobile phone with your head down, the cervical spine often bears heavier head weight, and at the same time, the shoulder and neck are overly tight and the cervical spine is burdened. After becoming a “head-down clan”, symptoms such as shoulder and neck muscle pain, back pain, and cervical spondylopathy will come to your door. Look down at the phone for no more than 15 minutes. It is best to keep the phone flush with the line of sight or slightly lower, keep your head upright, and don’t hunch back. Those who need to work with their heads down for a long time are advised to develop the habit of getting up and moving after one hour of work. When not busy, hold the back of your head with your hands and tilt your head back four or five times, with chest expansion and shoulder shrugs, so you can effectively relax! 5. Destroy bones all over the whole body-Qu Liuxin, director of the Department of Orthopedics and Traumatology of Zhongda Hospital of Chu Erlang’s legs, pointed out that the pelvis is tilted when Erlang’s legs are tilted, the lumbar spine is unevenly stressed, and the spine is arched while the body is tilted forward. Strain and deformation may even lead to lumbar disc herniation. People who have herniated discs and scoliosis problems will get worse. The normal spine of the human body is S-shaped when viewed from the side, but crossing the legs easily leads to a hunchback. Over time, the spine becomes a C-shape, which will compress the spinal nerves and cause pain. Crossing your legs will not cause you to get osteoarthritis immediately, but due to the increased pressure on the internal structure of the knee joint, the nutritional disorders and wear of the cartilage will increase. For the elderly whose cartilage structure has been degraded to varying degrees, it will increase the bone disease. The risk of arthritis. 6. Destroy the cervical spine-Sleeping on the tummy is the choice of many students and office workers for lunch break, but it hurts your neck without knowing it! Because this is not conducive to maintaining the physiological curvature of the cervical spine, it may cause cervical spine problems. People who have back pain or neck pain, especially cannot sleep on their stomachs, will aggravate the condition. It’s best to lie down for a nap. If conditions really do not allow it, you can sit on a chair with a cushion behind your waist and neck, lean back slightly, and simply rest for a while. 7. Destroy the neck—Holding a mobile phone between the head and shoulders to make calls When many people are busy at work, they are accustomed to sandwiching the mobile phone between the neck and the head. As everyone knows, excessive force of the cervical spine to one side may cause neck muscle spasm and excessive Fatigue, causing neck soreness and pain, buried
Knee joint pain is often accompanied by knee joint swelling and limited extension and flexion. Common causes of knee joint pain include knee osteoarthritis or degeneration, rheumatoid arthritis, gouty arthritis, trauma, tumors, congenital deformities, etc. All of the above reasons can damage the joint structure and cause knee pain. In the acute stage of knee joint pain, you need to brake, wear knee pads, reduce the amount of activity, avoid climbing, long walking, squatting and other movements, take appropriate rest, and do physical therapy if necessary. What if I walk a lot and my knee joint is uncomfortable and painful? Try these teas. The nutritionist recommends 20 grams of raw ramie and 6 grams of fangfeng tea. The above 2 flavors are decocted with water, and the slag is removed and the juice is used to replace the tea. Yami Fangfeng Tea has a certain effect of clearing heat and dampness, dispelling wind and relieving pain. Yami Fangfeng Tea mainly regulates the knee joints and limbs arthralgia caused by rheumatic heat invasion, and those with swelling and fever. Walnut tea takes 10 grams of walnut kernels, 10 grams of sesame seeds, and 5 grams of fine tea leaves. The above 4 flavors are added with water and decoction instead of tea.
Many people don’t know that arthritis is the world’s number one disabling disease. There are more than 100 types of arthritis, rheumatoid arthritis ranks first in terms of disability rate, and the largest number of patients is osteoarthritis. The prevalence of osteoarthritis is very high. Among people over 60 years old, more than half are affected, and the incidence rate over 70 years old is as high as 70%. Osteoarthritis can occur in the joints of the whole body, and the knee joint is the most common. According to statistics, the number of knee osteoarthritis patients in my country exceeds 50 million. Cartilage wear is the root cause of osteoarthritis, and cartilage wear is happening all the time! In a normal joint, bone and bone will not rub directly. This is because there is articular cartilage covering the two opposite bone surfaces that constitute the movable joint, which is equivalent to a “cushion pad” in contact between the bone and the bone, which transfers the load evenly. Enlarge the joint load-bearing surface and reduce contact stress, and reduce friction. When we studied physics, we knew that friction = friction coefficient x pressure. The knee joint is one of the most active and weight-bearing joints of the human body. The pressure is mainly derived from body weight. The friction coefficient is determined by the composition of cartilage and the smoothness of cartilage surface and joints. The lubrication of synovial fluid is determined. The friction coefficient of normal articular cartilage is 0.002~0.01, which is significantly lower than that of artificial joints. However, with age, the composition and structure of cartilage will change, and the composition of joint synovial fluid will also change. The increase in friction coefficient will make the articular cartilage more likely to be worn out. If it is caused by overweight, heavy work, and strenuous exercise. The knee joint is under increased pressure, and the wear rate of articular cartilage is further accelerated. As long as the knee joint is movable, the cartilage wear will always exist, which lays the foundation for osteoarthritis. In the process of continuous wear and tear of the cartilage, the cartilage debris that is worn off fills the joint cavity, which will induce inflammation, and the joint will have inflammatory reactions such as swelling, heat, and pain. In turn, inflammation will further accelerate the destruction of cartilage. As cartilage destruction intensifies, the subchondral bone ends will be exposed, and the bone ends will rub against each other, which will cause bone hyperplasia, and the growth of bone spurs will further aggravate the destruction of cartilage. In short, if the joint cartilage is left to wear and tear, osteoarthritis will soon come to the door. There are several stages of articular cartilage wear. How to find out early? Plain X-ray film can clearly show the changes of joint space and bone, which is the preferred imaging method for the examination of osteoarthritis. X-ray manifestations of osteoarthritis are mainly joint space narrowing, subchondral bone sclerosis, osteophyte formation caused by the destruction of articular cartilage, and joint instability, joint deformity, intra-articular loose body and sub-articular cystic degeneration. X-ray plain film is the preferred imaging examination for osteoarthritis. The radiological classification standard for knee osteoarthritis is: 0: no signs of OA, 1: suspected joint space stenosis and possible labial osteophytes, 2: exact osteophytes And possible joint space stenosis grade 3: moderate osteophytes, exact joint space stenosis, partial subchondral sclerosis and possible bone end deformity. Grade 4: A large number of osteophytes, a significant narrowing of the joint space, severe subchondral sclerosis and exact bone end deformities. Due to its traumatic nature, arthroscopy cannot be used as a routine diagnostic method for cartilage damage. However, the earliest changes in osteoarthritis are articular cartilage. X-ray films can only be used to judge the damage of cartilage based on changes in joint space, and cannot directly show cartilage changes. , The lack of specific signs in the early stage often delays diagnosis. Although arthroscopy is the gold standard for evaluating articular cartilage damage, it can directly observe the swelling, erosion and ulcers of hyaline cartilage, but it cannot show deep cartilage changes and subchondral bone changes. Because of its traumatic nature, it cannot be used as a routine diagnostic method. . At this time, we need MRI. MRI can show cartilage changes early and is more accurate in detecting early osteoarthritis. MRI cartilage damage classification standards are as follows: Grade 0: normal; Grade 1: abnormal signals in cartilage but normal on the surface (corresponding to arthroscopic swelling); Grade 2: mild surface irregularities, or local thickness thinning by 50% Below; Level 3: The surface is severely irregular, and the thickness is reduced by 50% to 100%; Level 4: The cartilage is completely lost and the bone is exposed. The MRI classification standards for knee osteoarthritis are as follows: Grade 0: No cartilage damage, no or very small osteophytes (<5mm); Grade 1: Cartilage damage grade I, and at least one of the following conditions: osteophytes>. 5mm, bone marrow edema >.10mm, subchondral cyst >.10mm; grade 2: cartilage injury grade Ⅱ,
When a patient with rheumatoid arthritis first attacks, it may be misdiagnosed as acute traumatic synovitis. In addition to misreading the department and other reasons, it is also related to the characteristics of rheumatoid arthritis joint synovial inflammation. What is joint synovium? Why does the joint synovium appear inflammation? Why does rheumatoid arthritis cause inflammation of the synovium? Through this article, we will learn the answer together! What is joint synovium? The joint synovium is a layer of smooth, bright, pink, thin, and soft loose connective tissue that adheres to the inner surface of the fibrous layer of the joint capsule, attaches to the periphery of the articular cartilage, and covers except for the articular cartilage, joint discs and fibrocartilage meniscus. All structures in the joints except the central part of the plate. The thickness of the normal joint synovium is about 1~3μm, which is divided into the inner synovial layer and the subsynovial layer near the joint cavity. Joint synovium not only protects the joints, but also has many functions: the main role of synovial cells is to synthesize hyaluronic acid, fibrin, collagenase and other promoting factors, which can not only protect joint cartilage, but also on inflammatory cells The phagocytosis plays a role in promoting. Joint synovium also produces joint synovial fluid, which can not only provide “lubricant” for joint activities, reduce the wear of articular cartilage, increase the range of joint activities, and provide nutrition for other tissues in the joint. The synovial membrane of the knee joint also has the function of attaching and removing joint foreign bodies and debris. Where does the “inflammation” of synovitis come from? The production and absorption of joint synovial fluid is “dynamic balance”. When joint synovial fluid has reabsorption disorder, the dynamic balance is broken, and the production of joint synovial fluid is greater than the absorption, and “joint effusion” appears. Synovitis is a kind of joint disease in which the tissue with synovial membrane is stimulated by various reasons and undergoes inflammatory changes, resulting in imbalance of synovial cell secretion and fluid accumulation. When there is a certain irritant in the joint, whether it is bacterial, physical or chemical, the synovial membrane will react first, causing congestion and edema, and exuding fluid, causing the joint to swell, showing joint swelling. The knee joint is the most important site of synovitis. The knee joint is the joint with the most synovium, the largest articular surface and the most complex structure in the human body. It is also one of the joints with the greatest burden and the most movement in the human body. The synovium of the knee joint is extensive and located in the shallower part of the limb surface. There are many reasons for the synovium There are more opportunities for injury and infection, and a greater probability of synovitis. “Acute traumatic synovitis” knee joint synovitis is mostly caused by knee sprains and various intra-articular injuries, such as meniscus injury, synovial injury, cruciate ligament or collateral ligament injury, resulting in intra-articular fluid or Hemorrhage, rapid swelling of the joints, protective spasm of the muscles around the knee joint, limited extension and flexion, and a positive floating patellar test. This is acute traumatic synovitis. For simple acute traumatic synovitis, cold compresses and compression bandages can be used before large amounts of hemorrhage in the early stage, and the knee joint can be fixed with a plaster cast for 2 weeks. After 48 hours, physical therapy can be cured quickly. For those with joint effusion, the effusion should be removed under aseptic operation, and then the hemorrhage in the joint should be washed away repeatedly with normal saline, pressurized and bandaged and immobilized. “Chronic synovitis” A condition of chronic synovitis is caused by incomplete treatment of acute traumatic synovitis. In addition, it may also be caused by simple knee synovial damage, such as mild trauma or long-term chronic knee Joint strain, coupled with the invasion of wind, cold, and dampness, can cause swelling and dysfunction of the knee joint gradually. Chronic knee synovitis mainly manifests as joint swelling, soreness, and limited mobility. Synovial hypertrophy, floating patellar test is positive, hypertrophic synovium touches with friction sound, mild tenderness, and the elderly may have joint ligament laxity and articular cartilage softening. “Infectious synovitis” Another cause of synovitis is infection. Synovial tuberculosis is the most common. Under normal circumstances, the synovium is rich in blood vessels and has good blood circulation, and has strong resistance to bacteria. However, in the case of Mycobacterium tuberculosis infection, the progress is slow, and the symptoms are sometimes good and sometimes bad. This is also the knee joint A type of chronic synovitis. “Immune synovitis” This type of synovitis is mainly caused by abnormal immune substances. The synovial membrane in the joint is mistakenly attacked by the autoimmune system, resulting in swelling, pain, stiffness and other inflammatory reactions. Diseases that can cause immune synovitis include autoimmune arthritis such as rheumatoid arthritis and osteoarthritis. Can synovitis be anti-inflammatory with antibiotics? Some patients with acute traumatic synovitis, after being diagnosed in the hospital, the doctor ordered “attention to rest and physical therapy,” but did not order anti-infective treatment. The patient was still very puzzled: No
O-legs, also known as looped legs, are a type of leg deformity where the gap between the knees is too large. In the movie “Hands Up” starring Pan Changjiang, the Japanese soldier he plays is an O-leg. Many people don’t know that O-legs are also a risk factor for knee osteoarthritis. People with O-legs are more likely to develop knee joint degenerative lesions. As the disease progresses, knee osteoarthritis is also prone to develop or aggravate O-legs. Next, let’s take a look at how to prevent these situations! This knowledge of O-legs must be understood! (1) What is an O-leg? O-shaped legs are medically called “knee varus”, that is, the lateral angle of the knee joint exceeds 180°, the double iliac bones are internally buckled, and the ischia is extended. When the lower limbs are naturally straightened or standing, the inner ankles of the two feet can touch each other. The two knees cannot be brought together as the main deformity disease. (2) What are the hazards of O-legs? The hazards of O-shaped legs are mainly reflected in two aspects of appearance and health. People often only see the hazards of O-shaped legs in appearance, but do not know the hazards of O-shaped legs in health. The hazards of O-shaped legs: The knees of O-shaped legs turn inward, and the knees cannot cause a huge gap between the legs, which looks very unsightly. Due to severe changes in the thigh curve, O-legs will look short from the front, and the upper and lower limbs will be out of proportion; O-legs have more muscles on the outer side of the bones and less muscles on the inner side, which causes the contours of the lower limbs to shift outward. , The hips are wide, and the calves are particularly bent; O-legs are too heavy to concentrate on the inner side of the knee joints, and they are not suitable for walking to maintain balance. They are easy to swing and form duck steps! Health hazards of O-legs: People with O-legs have disordered lower limbs, with greater pressure on one side of the joint and relatively less on the opposite side. Over time, they are prone to pain when walking on the knee joint and suffer from knee osteoarthritis. People with O-legs are susceptible to direct or indirect discrimination and ridicule, which brings huge psychological pressure to the patient, and its psychological harm cannot be ignored. (3) Why do I get O-legs? Most of the formation of O-legs can be traced back to adolescence. In the process of physical development, teenagers do not pay attention to standing and sitting postures. Bad exertion habits such as heel valgus while walking make the muscle mechanics that dominate the joints imbalance, causing joints to shift, leading to incorrect leg shapes, which easily leads to O-legs . In addition, diseases such as trauma or rickets can also cause O-legs. (4) How to self-test for O-legs? If you self-test the following situations, you should consider whether you have an O-leg: The toes, ankles, and heels of the legs cannot be touched when the knees are brought together. When the toes, ankles, and heels of the legs are close together, even if the knees can touch, the thighs are not close together. When the toes and ankles of the legs are brought together, the heels cannot be touched. Only the outer side of the shoes that are often worn is severely worn. The human leg bones are more outside of the body than the pelvis. (5) How to determine the severity of O-legs? normal. In a standing posture, the inner ankles of the two feet can touch each other, and the knees can be close together. Mild О-shaped legs. The medial malleolus of the two feet are touching, and the distance between the medial sides of the knees is less than 3 cm. Moderate О-shaped legs. The medial ankles of the two feet are touching, and the distance between the two knees is between 3 and 10 cm. Severe О-shaped legs. The medial ankles of the two feet are touching, and the distance between the two knees is greater than 10 cm. Why are O-legs closely related to “osteoarthritis”? (1) Why are people with O-legs prone to osteoarthritis? In a normal knee joint, the pressure is evenly distributed on the articular surface, while for people with O-legs, the interval on the inner side of the knee joint is narrow and deformed, and the pressure on the knee joint will be biased to the inner side, resulting in the medial articular surface being subjected to movement With greater friction, articular cartilage is more likely to wear and tear, and therefore more likely to suffer from knee osteoarthritis. (2) Knee osteoarthritis can also cause O-legs! Cartilage wear is the source of knee osteoarthritis. If the cartilage on the outer side of the knee joint is worn away, the patient will not be able to exert force properly when walking in order to avoid pain, which may also cause joint deformation, resulting in O-shaped legs. However, if people with O-legs develop knee osteoarthritis, they may further increase the flexion strength of O-legs if they do not respond correctly. (3) How can people with O-legs prevent knee osteoarthritis? Knee osteoarthritis is a chronic joint disease characterized by the degeneration, destruction and bone hyperplasia of articular cartilage. Compared with normal people, people with O-legs are more likely to suffer from knee osteoarthritis. The reason is that the knee joint is not evenly stressed to prevent knee osteoarthritis. People with O-legs should pay more attention to reducing the burden on the knee joint: maintain a normal weight . The greater the weight, the greater the pressure on the knee joint, which will cause the articular cartilage to degenerate faster. At the same time, overweight and obesity can lead to unbalanced joint forces, resulting in increased O-leg flexion strength. Maintain positive

Knee joints also have years of use. The greater the responsibility, the greater the pressure. As a weight-bearing joint of the human body, the knee joint bears not only the weight of the person, but also the extra pressure generated by the human body in different postures and movement forms. The weight of the knee when walking is 3 times the weight. The weight of the knee when going up and down the stairs is 4 times the weight. The weight of the knee when running is 5.5 times the weight. Imagine: a person weighing 60 kg, every step of the step, the knee will bear a weight of 240 kg, which is susceptible to injury. At the same time, because the knee synovium is distributed in the shallow parts of the limbs, the chance of infection is also higher. . So in fact, our knee joint has a “use period”: *Before 15 years old, the knee joint is still in the developmental stage. *15~30 years old, the knee joint reaches the “perfect state”. *30~40 years old, the patellar cartilage is produced early Mild wear. * 40 to 50 years old, knee joint discomfort. * After 50 years old, patellar cartilage faces full-thickness wear. How to protect the knee and reduce the probability of injury? 1. Appropriate training First of all, we must know when our knee is most likely to be injured. First of all, of course, excessive use of the knee can easily cause fatigue in the knee joint, so blindly pursuing high-intensity training can easily cause injury, and moderate exercise is the best. 2. Do a good warm-up Before training, there is a link that many people will ignore, that is to do a good warm-up. Without adequate warm-up preparations, the muscles will become stiff, and the subsequent exercise will easily increase the pressure on the joints and cause knee injuries. 3. Correct posture If you are a person doing fitness, then you should pay attention to it. Did your movements really achieve the position? The wrong posture will also increase the pressure on the knee, for example, the squat will focus on the wrong Position, it will cause pressure on the knee. 4. Strengthen muscles At the end, it is the right way to strengthen your own body. While doing a good job of protection, the exercise of muscles cannot be ignored. When your muscles can withstand the relative amount of exercise, it is also equivalent to protecting the knee.
I often hear similar questions: My knees always “click”, what’s going on? Is the joint damaged, or is it calcium-deficient? Many people are worried, so they go to the hospital for consultation. What is going on? Today, let’s talk about the common causes of knee bounce. Knee bounce, there is a professional term called “bounce the knee”, which refers to the sound and vibration of the knee when the flexion and extension activity, the tendon around the joint sliding or joint impact. Knee joint bounces can be divided into physiological bounces and pathological bounces: as the name implies, physiological bounces are normal when normal people sit for a long time and stand up or squat or go upstairs, the knee may be There will be a clicking sound. Physiological bounce generally only occurs when the joint is suddenly pulled or flexed, and the sound is crisp, single, and not repeated; it often takes a period of rest after a sudden movement to be induced again. This kind of simple knee joint bounce is not accompanied by any pain and discomfort, it is a normal phenomenon, so you don’t need to worry about it or worry about it. Not only the knee joint, but also other joints will make this sound when they are stretched or flexed, such as the common snapping sound of pulling fingers and breaking fingers. Pathological snapping is pathological, there is a lesion, you need to pay attention! If the articulation of the joints occurs repeatedly and does not require a rest period, or is accompanied by discomfort or pain at the same time, then you must pay attention to this kind of elasticity is pathological. This snapping may indicate a change in the structure within the joint. Many diseases of the knee joint are related to it and need attention. Meniscus injury is the most common cause of pathological bounce in young people. The meniscus is a pair of half-moon-shaped cushions in the middle of the knee joint. Under normal circumstances, it is smooth and Flexible. If the meniscus is torn, it may be stuck between the joints, there will be a noise when the knee joint is flexed and extended, and sometimes it is accompanied by pain or interlocking (the so-called interlocking is to feel the knee joint is stuck and must be active. In order to stretch again). In addition to meniscus injury, some congenital developmental abnormalities of the knee joint structure such as discoid meniscus, patella dysplasia, etc.; aging and degeneration of the knee joint; free body in the knee joint; old ligament damage can cause snapping. Combined with the above description of physiological bounce, if you suspect that the bounce is pathological, then you should pay attention to it, go to the hospital in time, and do further processing based on the results of the doctor’s physical examination. How to protect joints and prevent pathological snapping? 1. Scientific training to avoid injury; 2. Strengthen the muscle strength around the knee joint. The muscle strength is strengthened, which can improve joint stability and further protect the joint. Commonly used simple training method: Isometric contraction training of quadriceps: In short, isometric contraction exercises of quadriceps are the stretching exercises of muscle groups in front of thighs. Straight leg raising to strengthen quadriceps training: supine, knee extension, ankle back extension, raise the patient, 30-50° from the bed surface, insist for 10 seconds each time, 30 times per group, 6 per day group.
. The two milky half circles in the middle are the meniscus 1. What is the meniscus? what’s the effect? The meniscus is composed of fibrous cartilage, with a piece inside and outside, located in the middle of the knee joint and connected to the ligament. The structure of the meniscus is a semi-annular shape, with a thick outer periphery, a thin and sharp inner edge, a concave top, which is compatible with the femoral condyle, and a flat bottom which is compatible with the tibial plateau.  . Because of the meniscus, the knee joint is divided into two groups: thigh-meniscus and meniscus-tibia. The meniscus can increase the stability of the joint and prevent the surrounding soft tissue from being squeezed into the joint. The color of the meniscus is off-white, smooth and shiny, tough and has a certain elasticity, can cushion the impact of two bone surfaces, absorb shock, spread synovial fluid, increase lubrication, reduce friction, and protect joints. 2. Why did the meniscus tear? Meniscal tears are divided into: chronic degeneration tears and acute traumatic tears. The former is related to aging and repeated chronic injuries. As the human body grows older, the cartilage becomes weaker and gradually thins. Aged, worn tissue is more likely to tear. When the meniscus weakens with age and may stand up from the chair, only a slight turn is enough to cause a tear. The latter is related to sports injuries. More common in young people, when the joints suddenly rotate and violent movements cause tears. Sudden rotation of the femur makes the meniscus move to the center and causes edge tears. The knee joint is flexed and flexed so that the posterior angle and body of the meniscus are compressed between the tibial joints, causing tearing. 3. What is the impact after the meniscus tears? When the meniscus is torn, you may feel a bang. Most people can still walk with injured knees after being injured. Many athletes can still engage in sports after tearing. After 2-3 days, your knees will gradually become stiff and swollen. The most common symptoms of meniscal tears are: pain, stiffness, swelling, soft legs, and limited mobility. 4. Can meniscus tears be treated non-surgically? If your rift is small and is on the outer edge of the meniscus, it may not require surgical repair. As long as your symptoms do not persist and your knees remain stable, non-surgical treatment may be all you need. RICE procedure: For most sports-related injuries, the RICE procedure is effective. RICE is the first letter of the four English words for rest, ice compress, pressure bandaging and raising the affected limb. Rest: Stop the exercise that caused the injury. Your doctor may recommend that you use crutches to avoid increasing the burden on your legs. Ice pack: Use an ice pack for 20 minutes each time, several times a day. Do not apply ice directly to the skin. Compression bandage: To prevent additional swelling and blood loss, elastic bandages can be used. Raise the affected limb: To reduce swelling, when you rest, you have to lie down and raise your leg above the heart. The use of non-steroidal anti-inflammatory drugs can reduce pain and swelling. If your symptoms are not relieved by non-surgical treatment, your doctor may recommend arthroscopic surgery. Method: Knee arthroscopy is one of the most common surgical procedures. Inside it, a miniature camera is inserted through a small incision. This can clearly observe the internal structure of the knee joint. Your orthopedist inserts micro-surgical instruments through other entrances to trim or repair the split. 4. How to treat meniscus tear surgery? Resection or suture? How to treat the meniscus depends on whether the red area of the meniscus is injured or not. From the meniscus blood supply (referring to the blood supply, the nutrients can only be sent to the cells of the tissues), the meniscus is divided into white area, red area and red-white junction area. The white area is the innermost, without blood supply, once the injury can not repair itself; the red area is the outermost, there is blood supply, the synovium is covered after the injury, and has a certain repair ability. 1. Suitable for suture If the torn part of the meniscus is in the red zone, the healing rate of the meniscus after our suture is very high, so we should try to sew it. 2. Suitable for resection. If tearing in the white area of the meniscus, sutures are generally not recommended, because after timely suture, it cannot absorb nutrients and will continue to be damaged. At the same time, resection is not complete resection. What we do is meniscus forming. Cut off the meniscus on both sides of the split, reshape the meniscus edge into a half-moon arc, and restore the anatomical shape of the meniscus. Basically, its function is still reserved, so don’t think that the knee joint is very good after the meniscus is removed. It will soon be abandoned. 5. Comprehensive meniscus tear is a very common knee injury. With proper diagnosis, treatment and rehabilitation, patients can often recover
Someone often tells me, what’s the matter with knee pain after running or kicking the ball? What are the specific reasons for the knee damage, and how to protect the knees during sports, this must be said below. To protect the knee, first of all, we must know the cause of the damaged and painful knee. In general, there are the following reasons: 1. The patella softens, and the cartilage tissue of the knee (that is, the patella) and its connection part will be resonated during exercise. And pressure, the greater the weight, the higher the exercise intensity, the greater the probability of injury; 2. Meniscus injury, which is mostly caused by the external force of the knee joint torsion. When the lower leg of the load-bearing leg is in semi-flexion and abduction, the body and thigh suddenly Internal rotation, the medial meniscus is subject to rotational pressure between the femoral condyle and the tibia, which can easily cause the meniscus to wear or even tear; 3. Patellar tendinitis, the largest floating bone on the body, can protect the knee joint, it is staggered The friction of the quadriceps tendon against the cartilage surface of the femoral condyle prevents the function of excessive adduction, abduction, and extension and flexion of the knee joint. If the patella tendon becomes excessively fatigued, the tendon may become inflamed when the fibers are torn or other injuries occur. When the joints continue to exercise, the injury will further develop, and the pain will become more obvious or even worse; 4. Osteoarthritis, which is a non-infectious inflammation, is caused by overweight load, and long-term excessive exercise and incorrect running posture can cause Knee osteoarthritis. & nbsp. Now let’s talk about protection measures, in fact many people understand. The first is to open the knee joint before each running exercise, especially in winter, warm up before running, this can make the knee joint have a certain adaptation process, let the muscles and knees “warm up”, this not only can run better The state can also effectively reduce or even avoid sports injuries. The second is the running posture, the completion of a complete movement of running, one is the foot landing, the other is the body to maintain balance and move forward, and the third is to lift up, only such a correct posture, grasp the rhythm, can ensure effective exercise and no injury . Finally, after running, you need to stretch, which can not only relax the knee joint but also relax the tense muscles after running, promote the discharge of metabolic waste after running, and reduce the damage to the human body. Of course, you can massage and heat your legs for a short time before going to bed, which can better protect and promote the repair of knee joint wear. Therefore, although exercise is beneficial to health, exercise must be done to a certain extent. It is often recommended that moderate jogging can achieve the purpose of exercise. If you want to meet other requirements, you must formulate more details that suit you. The body is your own and exercise should be moderate. Doctor Yao Jinghui, the Third Affiliated Hospital of Southern Medical University (Guangdong Orthopedics Hospital, Guangdong Orthopedics Research Institute), hopes to help everyone’s health!
1. Is there lameness after acute sprain, such as one-handed waist support or the affected lower limb in a jump-and-jump gait for fear of weight-bearing, or a habitual body leaning forward with hips protruding to one side. 2. Is the lumbar spine deflecting to one side because of trying to avoid pain, and whether the deflection can relieve the pain to a certain extent. 3. Whether the pain is aggravated when sitting up, standing or walking, and is relieved when lying down. 4. Whether the symptoms of low back pain become worse during coughing, defecation or laughter, or leg pain and leg numbness. 5. After resting in the supine position, if the pain still can not be relieved, you can try whether the pain symptoms are alleviated in the lateral position, bending over, hip flexion, and knee flexion. 6. In the prone position, press the middle and both sides of the lumbar vertebrae by hand, whether there is obvious tenderness. 7. Supine position, then sit up and observe whether the affected lower limb can flex the knee joint due to pain. 8. In the supine position, straighten the knee joint on the affected side and raise the affected limb to see if the height is restricted due to pain.
We have talked about before, X-shaped legs, today I want to give you a popular science, another common leg type-O-shaped legs that are not good-looking. What is an O-leg? When the feet are upright, the two knees are separated, there is a large distance between them, and they cannot be close together. It is also commonly known as the “leg ring”. & nbsp. & nbsp. Why are there O-legs? The main reason is mostly the sequelae left after rickets in childhood, due to lack of vitamin D, calcium deficiency caused by bone softening; also caused by congenital diseases. What are the hazards of O-legs? First, it affects appearance and gait, which easily cause psychological inferiority and affect physical and mental health. Second, walking is easy to be unstable, easy to fall, and during intense exercise, the pressure on the inner side of the knee joint is large, which can easily cause joint wear and tear, causing osteoarthritis and causing pain. Third, it is easy to affect the hip joint, knee joint and ankle joint injury, causing a series of arthritis, especially in the middle-aged and old age. O-shaped legs affect the appearance and should be corrected as soon as possible. At a young age, it can be corrected by exercise: the first simple exercise is leg pressing, which can be positive or lateral; the second action is also very simple, kicking the leg, the calf is outward Kick the leg; the third action is the pinch leg movement, feet, knees, at the same time close and clamp, insist on relaxing after 3 minutes, practice 3-5 groups a day, after practice, pay attention to your walking posture, you must restrain yourself. Severe O-shaped legs need to go to the hospital to wear auxiliary equipment to correct it. Doctor Yao Jinghui, the Third Affiliated Hospital of Southern Medical University (Guangdong Orthopedics Hospital, Guangdong Orthopedics Research Institute), hopes to help everyone’s health!
It is clinically found that it is impossible for children with cerebral palsy without correct upper extremity motor function to enter the training of street fine motor function. Therefore, the training of coarse motor skills should be carried out until the fine motor can be maintained well. At the same time, it provides children with experience of different hand feelings, and strengthens the cognitive training of opponents and eyes. For children with cerebral palsy, the main purpose of elbow rehabilitation training is to increase joint mobility, improve children’s autonomous control of elbow joints, correct joint flexor spasm, and achieve joint flexion, extension, pronation, The supination function is normalized. Knee hyperextension The causes of knee hyperextension are: ① The knee joint itself has bony changes, resulting in an abnormal knee position. ②Under weight-bearing conditions, the knee joint has poor control ability, manifested by the disappearance of the knee joint proprioception, loosening of the ligaments around the joint, weak muscle strength of the quadriceps and hamstring muscles or contraction at a normal ratio. ③ Flexor contracture or muscle tension of the floor is high. ④ Abnormal massage and excessive force, causing iatrogenic injury. Training method: ① Improve quadriceps muscle strength training: transfer from sitting position to standing position. During the exercise, the therapist controls the child’s knee joints with both hands so that they do not overstretch; or sits on the chair or bed with both hands on the chair or bed and kicks the legs straight for 3-6 seconds. If it is easy to complete , Can apply appropriate resistance on the wrist of the child. ②Training to improve hamstring muscle strength: The child is in a prone position. Parents use one hand to fix their thighs, and use the other hand to hold the children’s ankles to help the children do flexion and leg extension. When the child completes this action independently, the hips may rise when the legs are bent flexibly. Parents can use their hands to fix their hips and apply appropriate resistance to the calves as appropriate. ③ Training to improve the strength of the dorsiflexor. Knee joint hyperextension due to plantar flexor contracture or high tension is important for this type of child: the therapist treats the patient with the plantar muscle when passively pulling the plantar muscle in the sitting or supine position. The therapist holds the ankle joint of the child in one hand and the upper third of the sole with one hand. When doing the dorsal flexion of 90 degrees or slightly, to perform the stretching activity, or when the child is prone, the therapist Fix the ankle joint with one hand: hold the upper third with one hand, and pull down with force (note: knee flexion 90 degrees). Or put a plank in front of the child’s feet and let the child squat for about 10 minutes, or let the child squat on a 30-degree slope for 10 minutes, 3 times a day. This method can be used on the gastrocnemius muscle and the floor flexor muscle. Pull. ④Knee joint control ability training: one is to fix the knee joint with stockings or elastic bands to control the knee joint hyperextension. The second is to put the child’s hands on the shoulders of the therapist. The therapist puts his hands on the outside of the child’s knee joint to control the knee joint, so that the child can squat down slowly and stand up slowly. Note that when the child is upright, the knee joint should be controlled in the middle position, and there must be no overextension. The range of squat should be determined according to the child’s ability to control the knee joint. The third is to let the child stand or squat, the therapist should pay attention to use language to control the hyperextension of both knees. The fourth is to control when the child is walking: the therapist controls the knee flexion of the child with the hand behind the child, and controls the knee hyperextension under language stimulation. Knee flexion The reasons for the formation of knee flexion: ① due to the bony changes of the child itself. ②The knee joint contracture is caused by not exercising for a long time or the joint is in a fixed position for a long time. ③Poor knee control ability and poor quadriceps muscle strength. ④The floor flexor and gastrocnemius muscles are abnormally exerted with high muscle tension. Training method: ① In the supine position of the child, the therapist holds the knee joint in one hand and the ankle joint in the other hand to perform the passive exercise of traction, so that the knee joint is fully straightened. After a few seconds, the hip and knee are bent, Pull again, 50 times each time. Pay attention not to apply too fast or too strong, and the force should not be too large, so as not to cause the knee joint to overstretch. ② The child stands in a standing position. The therapist helps the child to fix the hips with both hands. The therapist’s knees are aligned with the child’s knee joints (the children’s knees are close together). Straight waist, pay attention to proper force. ③The therapist is in the back, the child takes the standing position, the therapist fixes the two knee joints in the back of the child, the feet and knees of the child are close together, and the knee joint is straightened, then the child bends forward and down to touch his toes with both hands. The hamstring muscle is stretched, and if necessary, with the help of the parent of the child, the child’s buttocks are forced forward, so that the knee joint is fully straightened.
Because mothers work for the family for a long time and do the “logistical support” work, it is inevitable that they will ignore the health of the joints, and long-term fatigue will cause knee pain. There are many causes of knee pain, such as: fat pad strain, meniscus injury, knee traumatic synovitis, knee osteoarthritis, knee ligament injury, improper exercise, poor walking habits, lumbar spine or hip disease Wait. For middle-aged and elderly women, knee pain is commonly caused by knee osteoarthritis and osteoporosis caused by diseases of the lumbar spine or hip. Knee pain caused by osteoarthritis is more common in middle-aged and older women. Overweight load is the main cause of disease. If there is swelling and pain in the knee joint, there will be friction sounds during the movement, and the knee is deformed and accompanied by medial pain, etc., then osteoarthritis is highly suspected. Filming will help to confirm the diagnosis. In the treatment, if it is in the acute phase, more rest and less activity, if necessary, oral non-steroidal drugs, but the long-term application of these drugs will inevitably lead to many serious complications. Sodium hyaluronate can also be injected into the joint cavity. Knee osteoarthritis secondary to synovitis, fluid accumulation in the joint cavity, or severe pain, and other treatment effects are not good, only consider the use of hormones. For severe intra-articular lesions, if conservative treatment fails, artificial knee replacement is considered. Osteoporosis Osteoporosis can cause lumbar spine or hip lesions that affect the femoral nerve and cause knee pain and other symptoms. Most patients with knee pain can be in the lumbosacral region and the outside of the hip (tensor fascia lata, gluteus Muscles, gluteus maximus) and hips and the groin (adductor muscle group) were found to have obvious tenderness points. Calcium deficiency in postmenopausal women is a risk factor for osteoporosis. Older postmenopausal women have increased bone resorption, increased urinary calcium excretion, and dietary calcium needs to be appropriately increased. How to supplement calcium deficiency is not to blindly supplement calcium, because our body’s daily calcium absorption is limited, and it will not be absorbed if there is more. The elderly have poor stomachs, reduced nutritional elements, especially calcium intake, and reduced outdoor exercise, reduced vitamin synthesis in the body, and decreased intestinal calcium and phosphorus absorption. When we supplement calcium, we also need to supplement such as vitamin D, because vitamin D can promote the absorption of calcium. In addition, the skin can produce vitamin D, so we encourage the elderly to take more outdoor activities. The same is knee pain, there are many reasons, we have to figure out the cause of the pain before we can formulate a targeted treatment plan, instead of blindly dealing with it, simple calcium supplements cannot cure the disease, and the treatment requires not only indicators, It is necessary to cure the root cause. If there is a problem, you have to go to the hospital for consultation as soon as possible so that you can get more scientific advice and treatment without delaying the condition. Thanksgiving mother gave us life and love! Thanksgiving orthopedic doctors let the mothers regain their health! The greatest love is maternal love! Doctor Yao Jinghui, the Third Affiliated Hospital of Southern Medical University (Guangdong Orthopedics Hospital, Guangdong Orthopedics Research Institute), wish all mothers a happy Mother’s Day! Healthy body!
I & nbsp. The running posture is incorrect. It is necessary to know that the human body movement has its own force line. Incorrect posture will cause the lower limb anatomical force line to not be in the correct position, and the joint surface will move slightly, resulting in bad stress and damage The knee. Two & nbsp. Did not do enough warm-up exercise before exercise, activate muscle cell warm-up exercise can accelerate the body’s metabolism, promote blood circulation, increase muscle flexibility. On the contrary, muscle cell metabolism is low, muscle stiffness and flexibility are not enough, the muscles contract strongly during vigorous exercise, and increase the load on the muscles, causing damage. Three & nbsp. Overweight everyone who is running bears 4 times more pressure on their knees than running. For those who are overweight, the weight base is large, but their muscle strength is not enough, and the load on the knee joint is too large. Easy to cause knee injury. Four & nbsp. Excessive exercise intensity The human body has a limit. The body has an adaptive strength. After, it’s like the machine is overloaded. Easy to damage joints.
The knee has a wonderful structure, mechanical mechanics, biomechanics, trabecular bone strain, tribology, cartilage wear, repair, friction interface and stress changes, etc., are all professional joint doctors must consider in each treatment of. Fortunately, advances in technology, we have magical arthroscopy equipment, well designed prosthesis, we can provide patients with accurate diagnosis, arthroscopy, HTO, UKA, TKA precise surgical treatment. Moreover, with the support of comprehensive analgesia such as saphenous nerve block guided by our anesthesia expert Zhao Bo of Renji East Hospital, the patient did not feel pain after the operation. The strength of the integrated team allows us to restore the ability of painless sports for patients with knee joint pain. & Nbsp.
Children with cerebral palsy may experience a variety of disorders and postural abnormalities, and knee extension is one of the common symptoms. Many parents and patients will ask when they see a doctor: Doctor, why does the child have knee reflexion? Can knee reflexion not be treated? Professor Chang Chongwang of Northwest Cerebral Palsy Treatment Center said: “Knee reflexion must be dealt with, if Failure to deal with or even improper handling may lead to aggravation of the child ’s symptoms, or even severe disability in standing and walking. ”So, why do children with cerebral palsy have knee reflexion? Professor Chang Chongwang introduced as follows: 1. When children with cerebral palsy appear shares When the quadriceps is paralyzed or the muscle strength is low, the child’s hamstring muscle strength is weakened, and the knee joint is unstable in the straight position. At this time, if the weight is loaded, there will be forced to walk in the extended position. 2. When a child with cerebral palsy is paralyzed or has weak hamstrings and triceps of the lower legs, the back of the knee, including the joint capsule and ligaments, are relaxed, and the patient will show knee flexion. 3. When children with cerebral palsy have poor muscle movement control ability, the lack of simultaneous contractility can lead to instability of the child’s knee. 4. When a child with cerebral palsy develops excessive tension of the quadriceps muscle, especially the rectus femoris muscle, it causes stiffness in standing or supporting. The trunk flexes forward while advancing, and the gravity line falls in front of the knee joint, prompting the knee joint to extend to maintain balance . 5. When a child with cerebral palsy develops spasm or contracture of the triceps of the calf and the gravity line falls in front of the knee joint, compensatory knee flexion is formed. 6. When a child with cerebral palsy has sensory dysfunction in the knee joint body, the knee joint has poor control ability. At this time, in order to increase joint stability, the knee joint will be forced to lock in the posterior extension position and knee reflexion occurs. Finally, when a child with cerebral palsy has a long-term knee flexion deformity, it will cause patellar ligament relaxation. When the hamstring muscle is loosened, the child will have knee flexion, which is also a common cause of knee flexion in children with cerebral palsy.
