QUESTION Do females with patellofemoral pain syndrome have decreased hip muscle strength compared with the unaffected side and with healthy controls? DESIGN A systematic review of observational studies published up to January 2008. PARTICIPANTS Females with patellofemoral pain syndrome and healthy controls. OUTCOME MEASURES Strength for at least one hip muscle group had to be included in ...

BACKGROUND Patellofemoral complaints are frequently seen in younger and active patients. Clinical strategy is usually based on decreasing provoking activities as sports and demanding knee activities during work and leisure and reassuring the patient on the presumed good outcome. Exercise therapy is also often prescribed although evidence on effectiveness is lacking. The objective of this articl...

[Purpose] The purpose of this study was to evaluate the correlation between intrinsic patellofemoral pain syndrome (PFPS) in young adults and lower extremity biomechanics. [Subjects] This experiment was carried out with sixty (24 men and 32 women), who are normal university students as subjects. [Methods] All subjects underwent 3 clinical evaluations. For distinguishing the intrinsic PFPS from ...

OBJECTIVE To identify changes in impairments associated with functional and pain outcome in patients with patello-femoral pain syndrome following a standardized physiotherapy treatment. DESIGN One group pre-post design. SUBJECTS Seventy-four patients (median age 27 years, 52% female) diagnosed with patellofemoral pain syndrome and referred to physiotherapy treatment. METHODS Baseline meas...

Objective To compare the clinical efficacy of foot orthoses in the management of patellofemoral pain syndrome with flat inserts or physiotherapy, and to investigate the effectiveness of foot orthoses plus physiotherapy. DesignProspective, singleblind, randomisedclinical trial. Setting Single centre trial within a community setting in Brisbane, Australia. Participants 179 participants (100 women...

BACKGROUND Delayed onset of vastus medialis (VM) activity compared with vastus lateralis activity is a reported cause for patellofemoral pain. The delayed onset of VM activity in patellofemoral pain patients likely causes an imbalance in muscle forces and lateral maltracking of the patella; however, evidence relating VM activation delay to patellar maltracking is sparse. The aim of this study w...

Patellofemoral pain (PFP) is a frequent cause of anterior knee pain in athletes, which affects patients with and without structural patellofemoral joint (PFJ) damage. Most younger patients do not have any structural changes to the PFJ, such as an increased Q angle and a cartilage damage. This clinical entity is known as patellofemoral pain syndrome (PFPS). Older patients usually present with si...

Objective: To provide evidence regarding the therapeutic effects of exercise on subjects with patellofemoral-pain syndrome (PFPS). Data Sources: Evidence was compiled with data located using the Medline, CINAHL, and SPORTDiscus databases from 1985 to 2004 using the key words patellofemoral pain syndrome, exercise, rehabilitation, and strength. Study Selection: The literature review examined int...
