The role of arthroscopy in the treatment of groin pain after total hip arthroplasty: our experience

AimThe purpose of the study was to present our arthroscopic surgical technique and the results in patient with pain after a hip replacement.MethodsBetween November 2009 and September 2011, 35 patients with groin pain after total hip arthroplasty (THA) were treated arthroscopically. The patients underwent a preoperative examination consisting in careful history, physical examination, laboratory evaluation, diagnostic evaluation using x-rays and pelvis CT scans. In patients for whom the clinical picture suggested iliopsoas tendonitis, we also performed injection of local anaesthetic on the iliopsoas tendon sheath. All the patients were positioned in the supine decubitus position with traction applied, using 2 arthroscopic portals (AL, MID-A). An extensive debridement of adhesions, periprosthetic tissue and neocapsula were performed; when there were signs of iliopsoas impingement, a transcapsular tenotomy was performed according to Wettstein technique.ResultsThe average age was 57 (29-77) years old.
