Endoscopic fascia lata release for treatment of gluteal tendinopathy: a prospective study with a follow-up of 6 months to 1 year

Abstract

Greater trochanteric pain syndrome (GTPS) is clinically defined as greater trochanter pain with mechanical characteristics. The most common diagnosis is gluteal tendinopathy. Most cases of gluteal tendinopathy resolve with conservative management. In case of refractory pain endoscopic surgical treatment can resolved symptoms. This article presents a prospective study of endoscopic proximal fascia lata release associated to trochanteric bursectomy for recalcitrant trochanteric pain syndrome. 33 patients (35 hips) with refractory pain during more than six months were included. All patients were treated by endoscopic iliotibial band release and bursectomy according to Ilizaliturri. Outcomes were assessed by using Harris hip score and Womac hip score. Patients were follow-up until one year after surgery. The mean age was 53.7 years old, there was 9 men and 24 women. There were two bilateral cases in the female group. The average duration of conservative treatment was 20 months (CI95 9 to 31 months). 68% of patients were satisfied of the surgery with disappearance of pain after surgery. WOMAC and Harris hip score significantly improved after surgery until 6 months (respectively from 67 to 29 and from 40 to 76 - p<0.05). No complication was reported. Age, body mass index and duration of conservative treatment did not influence surgical results. This study showed that the endoscopic ilio tibial band (ITB) release and trochanteric bursectomy is simple, safe and easily reproductible but future prospective studies with a larger number of patients are required.
