BackgroundGreater trochanteric pain syndrome (GTPS) is clinically defined as greater trochanter pain with mechanical characteristics. Most cases of GTPS are resolved with conservative treatment. Surgical techniques are reserved for those who had unsatisfactory results with conservative treatment.PurposeThe aim of the present paper is to describe the outcomes observed within endoscopic treatment of peritrochanteric pathology.MethodsTwenty-three patients were included in the present study, undergoing surgery between January 2010 and December 2011, diagnosed with GTPS and surgically treated with endoscopy. All patients were evaluated with Visual Analogue Scale (VAS), Western Ontario and McMaster Universities Arthritis Index (WOMAC) Modified Harris Hip Score (mHHS) and Hip Outcome Score (HOS). The Scales were assessed before surgery and at 3, 6 and 12 months postoperatively.ResultsAll scores showed statistically significant differences (p < 0.001) within all periods.ConclusionThe endoscopic technique has proven to be safe and reproducible with good and excellent results, thus being an additional surgical procedure to consider within therapeutic management of greater trochanteric pain syndrome.Level Of EvidenceIV. Case series.
