Chondromalacia Patella (Runner's Knee)

Chondromalacia patella refers to the softening and breakdown of the cartilage on the underside of the kneecap (patella). It is one of the most common causes of chronic knee pain, especially in young athletes. The condition develops when the kneecap rubs abnormally against the thigh bone, causing irritation of the cartilage.
