Chondromalacia patellae

Overview chondromalacia patellae teenagers or young adult patients, mostly females, but there was no obvious athletes in gender differences. Patients patella cartilage rough, softening, fibrosis, fragmentation and shedding. The reasons for this are not entirely clear, but certainly with knee fatigue and chronic fatigue-related. Cause pathogenesis of the disease center patellar medial and partial medial (patellar medial inner edge is a separate small articular surface. with a medial ridge line separated). Early lesions, started in the deep and cartilage layer, cartilage collagen bundles were shrinking, but not violations of cartilage surface, Therefore no abnormal appearance of the surface, but the hand-to-cartilage can be found churning out feeling. If diseases continue to progress, cartilage were involved, occurred fracture and peeled off. Clinical manifestations rear knee medial patellar the secret anguish is the most common symptoms, or after exertion, down the stairs after aggravating. Sometimes a knee effusion. If interbody cage patellar medial patellar cartilage oppression may have tenderness in the front of femoral medial condyle are also a significant point tenderness. In knee extension and flexion, check the hand can be felt beneath the patella friction sound. Light at the course when heavy, sustainable years. X-ray often found no abnormality. Early treatment of the disease, should reduce the volume of activities knee with bandages or Light stent protection, if the symptoms persist few months to relax and not affect the work or living, should consider surgery. Many surgical methods have considerable failure rate. The cartilage lesion removed until the subchondral bone, and so bored improve blood supply, is commonly used method, But some prominent advocates of the practice within the femoral condyle, the patellar tendon only point moving inland, Quadriceps lateral expansion of the practice of the Department of release and prominent articular surface of the patella, and other.
