Patellofemoral pain syndrome, knee pain, bilateral PFPS, Hamstring 90-90 test,


Background and Purpose: Patellofemoral pain syndrome (PFPS) is characterized by musculoskeletal-related knee pain localized to the anterior retropatellar and/or peripatellar area of the knee. This case study describes the physical therapy management of bilateral PFPS. The results can be used to understand examination, evaluation, and interventions to treat PFPS.

Case Description: The patient was a 76-year-old female that reported progressive pain in both knees. She demonstrated weak hip abductors and extensors, tenderness upon palpation to bilateral pes anserine, bilateral ITB, and bilateral medial joint line with increased lateral tibial torsion on the left and a positive Hamstring 90-90 test.

Intervention: Therapy emphasized functional hip and knee targeted exercises in weight bearing and non-weightbearing positions. Exercises included strengthening and stretching of the lower extremities that would facilitate the patient’s return to prior level of function.

Outcomes: Upon discharge, the patient had increased hip and knee strength bilaterally, decreased pain, and improved her functional mobility as indicated by her decrease in disability score on the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC).

Discussion: Interventions aimed at increasing posterolateral hip musculature and improving functional mobility However, more research must be done regarding specific modes of exercise in order to develop and distinguish the best treatment protocol for PFPS. 1 CHAPTER I BACKGROUND AND PURPOSE Patellofemoral pain syndrome (PFPS) is a clinical diagnosis that is characterized b
