Young people with chondromalacia patella are not crippled and can be treated conservatively and surgically to maximize joint mobility and be able to regain their ability to live. Conservative treatment (1) General treatment In the acute stage, the swelling can be eliminated by braking, resting and applying ice, and the blood circulation can be strengthened by ankle pump exercise. In the later stage, quadriceps resistance exercise can be carried out to increase the muscle strength which is beneficial to maintain a good patella position and increase the stability of the knee joint. (2) Intra-articular injection of sodium hyaluronate can increase the viscosity and lubrication of the joint fluid, protect the articular cartilage, promote the healing and regeneration of the articular cartilage, alleviate pain and increase the mobility of the joints. 2. Surgical treatment Surgical treatment can be used if the strict non-surgical treatment is ineffective or if there is congenital deformity. Such as lateral capsular release, femoral epicondylar padding, scraping the patellar articular cartilage smaller erosion lesions, etc., to increase the stability of the patella in the process of femoral condyle sliding, and promote repair. It is recommended that patients seek timely medical standardized treatment to prevent knee dysfunction, so as not to miss the condition.
