what is maltracking
Patella maltracking, or patellofemoral pain syndrome, is an imbalance in the gliding of the kneecap that aggravates cartilage behind the knee. Rather than gliding vertically as the knee bends, a maltracking patella is pulled to the outward side as it moves upward in the groove. This may result in pain on the outward and front sides of the knee, clicking sounds, swelling, and pain from both activity and long bouts of sitting.
