Patellofemoral pain syndrome

Patellofemoral pain syndrome (PFPS) is a knee injury characterized by knee pain originating from the contact of the posterior surface of the patella with the femur.

PFPS pain is usually felt in the front of the knee and may be worse when sitting with bent knees for a long time, going up or down stairs, or when getting up from a seated position. Treatment involves pain management, patella bracing, lower extremity muscle strengthening, and stretching the hamstrings.
