Abstract

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.

KEYWORDS:

hip position; hip strength; kinematics; patellofemoral pain syndrome
