OBJECTIVES: To determine the efficacy of physical therapy on pain and physical function in patients with femoroacetabular impingement. DESIGN: Randomized, participant- and assessor blinded controlled trial pilot study. METHODS: This trial was registered at ClinicalTrials.gov (NCT01814124) and reported according to Consolidated Standards of Reporting Trials (CONSORT) requirements. Patients were randomly assigned to receive either a combination of manual therapy and supervised exercise (MTEX), plus advice and home exercise or advice and home exercise alone (Ad+HEP) over six weeks. Primary outcomes were average pain (visual analog scale) and physical function (Hip Outcome Score) at week seven. RESULTS: Fifteen patients, mean age 33.7 (SD 9.5, 73% female) satisfied the eligibility criteria and completed week seven measurements. The between group differences for changes in pain or physical function were not significant. Both groups showed statistically significant improvements in pain: the MTEX group improved a mean of 17.6mm and the Ad+HEP group, 18.0mm. CONCLUSIONS: The results of this pilot study provide preliminary evidence that symptomatic femoroacetabular impingement may be amenable to conservative treatment strategies however further full-scale randomized controlled trials are required to demonstrate this. In this small pilot study, supervised manual therapy and exercise did not result in greater improvement in pain or function compared to advice and home exercise in patients with symptomatic femoroacetabular impingement.
