![]() Decreased pain when ascending and descending stairs.Decreased highest intensity of pain experienced during the previous week.A recent systematic review conducted by Santos and colleagues 9 found gluteal strengthening to have the following effects amongst individuals diagnosed with PFPS. In support of a gluteal etiology, several studies have found the effectiveness of gluteal strengthening in the treatment of lower extremity disorders. 8 Gluteal Strengthening and Rehabilitation In addition to patellofemoral pain, a hip etiology or influence has also been implicated in iliotibial band syndrome, 6 anterior cruciate ligament rupture, 7 and achilles tendinopathy. This excess femoral adduction creates an increased valgus force about the knee joint, which in turn causes increased loading of the lateral patellofemoral joint. 5 found that individuals presenting with PFPS demonstrated increased hip adduction during running, jumping, and single-leg squats. ![]() Wilson et al., 3 Noehren et al., 4 and Nakagawa et al.The PFPS group also demonstrated 14% weaker hip abductor strength and 17% weaker hip extensor strength. 2 found that females with patellofemoral pain syndrome (PFPS) demonstrated greater peak hip internal rotation compared to the control group during running, drop jump, and step down. Just 10° of IR can lead to a substantial decrease in PFJ contract area and a 50% increase in joint stress. Because during weight bearing the femur moves about a fixed patella, excessive femoral internal rotation (IR) and adduction results in increased contact primarily at the lateral facet of the patella. The gluteal musculature has been implicated in many different pathologies due to its potential impact on lower extremity biomechanics.
