what causes pain in your knee caps?
Pain on the front part of the leg that is felt deep in the center of the knee can often be from wear of this cartilage. This cartilage wear is called chondromalacia and the pain syndrome may be called patellofemoral syndrome (or PFS for short). There are many causes for anterior knee pain. Overuse in work or exercise, sports injuries, arthritis, and even flat feet have been implicated in causing this type of pain.
