Hip and Knee Exercise for Patellofemoral Pain: Using the Evidence to Guide Physical Therapist Practice.

Abstract

The etiology of patellofemoral pain (PFP) is thought to include both local factors (those near the patellofemoral joint and surrounding tissues) and nonlocal factors (those related to the mechanics of the distal and proximal joints). Traditionally, PFP rehabilitation protocols have focused on local factors. Strengthening of the hip may reduce excessive hip adduction and medial rotation during weightbearing activities and so decrease patellofemoral joint stresses. However, while previous studies indicate that including hip strengthening may lessen the intensity of PFP, the effects on strength and activity remain uncertain.
