CHONDROMALACIA

Chondromalacia (sometimes also called patellofemoral pain syndrome) occurs when the cartilage under the kneecap is softened or damage abnormally. This cartilage allows your femur (thigh bone) and kneecap to glide smoothly over one another when you walk or move. Irritation in this area can cause varying degrees of pain, depending on if the damage is minor or severe. In fact, chondromalacia is one of the most common causes of chronic knee pain.
