What is chondromalacia patellae

First of all, patella (kneecap) and femoral condyle constitute patellofemoral joint. Such diseases are not only congenital, but also postnatal. The acquired diseases are mainly caused by not paying attention to protection or excessive exercise intensity during normal exercise.

Secondly, chondromalacia patellae is caused by the disorder of the biomechanical relationship of patellofemoral joint. The patella inclines outwards or subluxates, which causes the articular cartilage inside the patella to strike the femoral condyle trochlear, causing excessive wear of articular cartilage in the lateral space (as shown by the arrow in Figure 1), chondrocyte abscission, bone hyperplasia, joint space stenosis and a series of pathological changes Clinical symptoms: pain in the front of knee joint, aggravation of pain when sedentary standing up or going downstairs or downhill, weakness of legs, fear of cold joint, or repeated swelling and effusion of knee joint, etc. Severe osteoarthritis, so early diagnosis, take reasonable preventive measures to prevent its occurrence or development is very important.

Finally, any age can appear, athletes and elderly female patients are more common, many children get the so-called "growth pain", often associated with the disease. In the early stage, teenagers show pain in the front of the knee joint and get better after rest. With the extension of the course of the disease, the pain time is more than relief. When they go downstairs, they get worse. When they go downstairs or walk, they often need to go sideways and horizontally. When they go downstairs or walk, they often suddenly feel powerless to wrestle. They are commonly known as "soft legs". They are afraid of cold in the knee joint and can repeatedly swell and accumulate fluid. They are often misdiagnosed as "rheumatism". When the condition further develops, it is difficult to squat down and has pain at night, which affects sleep and normal life. In the late stage, due to severe wear and tear, the knee joint can not be fully straightened, and there may be joint hydrops and free body in the joint cavity, resulting in intra-articular strangulation and sudden seizure of the joint.
