Risk Factors for Patellofemoral Pain Syndrome

Patellofemoral pain syndrome (PFPS) is a common source of anterior knee in pain females. PFPS has been linked to severe pain, disability, and long-term consequences such as osteoarthritis. Three main mechanisms have been proposed as possible causes of PFPS: the top-down mechanism (a result of hip weakness), the bottom-up mechanism (a result of abnormal foot structure/mobility), and factors local to the knee (related to alignment and quadriceps strength). The purpose of this study was to compare hip strength and arch structure of young females with and without PFPS in order to detect risk factors for PFPS
