Chondromalacia Patella (Patellofemoral Syndrome/Runner's Knee)

This is an overuse syndrome of the articular cartilage of the patella that stems from malalignment of the patellofemoral tracking complex. It is the most common cause of knee pain (frequently seen in female athletes) and is often bilateral.
