Patellofemoral Pain Syndrome (PFPS) is a common musculoskeletal disorder typically occurring in physically active people aged 40 years and younger, causing pain, functional deficits and lower limb weakness. Traditional treatment has been aimed at strengthening the knee, however recent research suggests the muscles around the hip also play an important role in the development and continuity of Patellofemoral Pain Syndrome. Purpose: To investigate the effectiveness of the addition of hip strengthening exercises to standard physiotherapy treatment (knee strengthening and stretching exercises) on reducing pain, and enhancing strength and function when compared to standard physiotherapy treatment alone in adults with Patellofemoral Pain Syndrome. Method: A systematic search of Cochrane, CINAHL, Embase, MEDLINE®, PEDro and SportDiscus was conducted. Studies of participants aged 18 to 44, diagnosed with Patellofemoral Pain Syndrome by a healthcare practitioner, or reporting peripatellar or retropatellar pain with common functional tasks, were included. A critical appraisal, using the Critical Appraisal Skills Program for Randomised Controlled Trials (CASP) was used to assess methodological quality. Results: Five randomised controlled trials of varying methodological quality met the inclusion criteria. The participants in these studies were aged between 18 to 40 years of age. The duration of the intervention ranged from four to six weeks consisting of 12 to 30 supervised exercise sessions. Studies used varying outcome measures for each of the three outcomes. Overall, the studies demonstrated that the addition of hip strengthening exercises to standard physiotherapy care consistently improved pain and function, but the impact on strength was variable. Conclusion: Previously, only a small number of studies have looked at the addition of hip exercises to standard physiotherapy care for treatment of Patellofemoral Pain Syndrome. While there is a growing body of evidence for the efficacy of hip strengthening exercises for Patellofemoral Pain Syndrome, this is constrained by bias towards female participants, lack of true controls in most studies, and low methodological quality of studies overall. Hip exercises added to standard physiotherapy care shows potential as a treatment method for improving outcomes of pain and function in adults with Patellofemoral Pain Syndrome.

Background: Focus on the importance of hip muscle strength in patients with patellofemoral pain syndrome (PFPS) has recently increased. It is unknown whether patients with PFPS will benefit more from hip strengthening compared with traditional knee-based strengthening. Purpose: To compare the efficiency of isolated hip strengthening versus traditional knee-based strengthening for patients with PFPS. Study Design: Systematic review; Level of evidence, 2. Methods: We conducted a search for studies comparing isolated hip strengthening and knee-based strengthening by using the MEDLINE, Embase, and Cochrane Library electronic databases. The methodological quality of included studies was assessed using the PEDro scale. Predetermined variables from each study were extracted and analyzed. Results: A total of 5 comparative studies were included in this review; all studies were of moderate to high quality and reflected good internal and external validity. Pain (visual analog scale [VAS]) and function (Anterior Knee Pain Scale) scores improved in both the hip and knee groups after strengthening intervention, although no statistically significant differences were seen between groups in the pooled analysis. In 2 studies, VAS pain scores were reduced earlier for patients in the hip group than for those in the knee group ( P < .05). In 1 study, improvement in Western Ontario and McMaster Universities Osteoarthritis Index function scores in the hip group was statistically superior compared with those in the knee group after intervention and at 6-month follow-up ( P < .05). In 2 studies, patients in the hip group exhibited statistically greater hip abductor and extensor strength than did those in the knee group after intervention ( P < .05). Conclusion: The best-available evidence suggests that overall, isolated hip strengthening and knee strengthening were equivalent for treatment of PFPS.
