Sports Science and Medicine: chondromalacia patellae

Deterioration and softening of the articular cartilage lining the undersurface of the kneecap. The damage is usually caused by repetitive rubbing of the kneecap on the femur. It sometimes, but not always, causes a patellofemoral pain. However, it should not be assumed that all such pain is due to chondromalacia patellae . Treatment of chondromalacia patellae includes non-steroidal anti-inflammatory drugs (NSAIDS) to reduce inflammation, and strengthening and stretching exercises to improve the structures around the knee.
NSAID
A drug, not related to steroids, which has anti-inflammatory and pain-reducing properties. Commonly used NSAIDs include naproxen and acetylsalicylic acid (aspirin). NSAIDs are widely used in the treatment of acute soft tissue injuries, but less so for chronic injuries such as tendinitis. The exact mechanism of action of NSAIDs is not known, but they are thought to reduce the synthesis and release of prostaglandins. NSAIDs are permitted by the International Olympic Committee for use by athletes.
