Context: Patellofemoral pain syndrome (PFPS) is one of the most common conditions limiting athletes. There is a growing body of evidence suggesting that dysfunction at the hip may be a contributing factor in PFPS.
Data Sources: MEDLINE (1950–September 2010), CINAHL (1982–September 2010), and SPORTDiscus (1830–September 2010) were searched to identify relevant research to this report. Study Selection: Studies were included assessing hip strength, lower extremity kinematics, or both in relation to PFPS were included.
Data Extraction: Studies included randomized controlled trials, quasi-experimental designs, prospective epidemiology, case-control epidemiology, and cross-sectional descriptive epidemiology in a scientific peer-reviewed journal.
Results: PFPS is associated with decreased hip strength, specifically at the abductors and external rotators. There is a correlation between PFPS and faulty hip mechanics (adduction and internal rotation).
Conclusions: There is a link between the strength and position of the hip and PFPS. These patients have a common deficit once symptomatic. Hip strengthening and a coordination program may be useful in a conservative treatment plan for PFPS.
