Chondromalacia Patella

Chondromalacia is the most common cause of chronic knee pain. It develops due to the softening of the cartilage beneath the knee cap as a result of overuse, injury, or other factors.

The cartilage is a natural shock absorber which can erode as the knee cap rubs against the femur instead of gliding smoothly over the knee.
