What is Chondromalacia Patella?

Chondromalacia patella is a medical condition that causes knee pain. It is also known as the softening and breakdown of the tissue on the underside of the kneecap. This condition occurs when the undersurface of the knee cap comes in contact with the thigh bone. Abnormal knee cap positioning, tightness of the muscles associated with the knee, too much activity involving the knee, and flat feet increase the likelihood of getting this condition. Chondromalacia patella is more common in people who are overweight, who have had injury or fracture, athletes, soccer players, bicyclists, other people who exercise, and teenagers. The symptoms of this condition include dull, aching pain behind the kneecap, below the kneecap, or on the sides of the kneecap, and a feeling of grinding when the knee is flexed, such as while knee bends, going down stairs, running downhill and standing up after sitting for a while.
