Knee extension disorder

Knee extension disorder is a clinical manifestation of knee arthritis. Knee arthritis: It can be single or bilateral, with more women and often overweight. Symptoms after middle age: I feel sore knee discomfort when sitting and standing, and symptoms disappear after a short walk. This is an early manifestation. The development of the disease does not alleviate the pain, and it should be difficult to get up and down the stairs or to squat and get up. You need to support your hands on your knees. After walking more, the knee joint is swollen or badly swollen, and some light yellow liquid can be drawn out. Due to the thickening of the synovium and the joint capsule, there can be sounds during movement. If there is free body formation in the joint, it can affect the joint activity, and there is a phenomenon of "joint lock" from time to time. In the end, knee deformities, such as knee flexion and contracture, O-shaped or X-shaped legs, and even crutches can walk.
