Arthroscopic treatment of type I and II greater trochanteric pain syndrome

The goal of this study was to describe and evaluate endoscopic bursectomy combined with fascia lata lengthening in the treatment of type I and II greater trochanteric pain syndrome recalcitrant to conservative management. This was a retrospective study of 20 patients (7 type I, 13 type II) reviewed with a minimum follow-up of 2 years. The mean follow-up was 44±11 [26-65] months. While significant improvements in pain, mHHS and NAHS were found, 80% of patients still had hip pain graded at≥3 on VAS. The satisfaction rate was 7/10±2 [3-10]. Snapping in the hip had been eliminated in 100% of cases. No complications were observed. This is a minimally invasive surgery that is feasible in patients who have failed an optimal course of conservative treatment. But patients must be informed that pain might not be completely eliminated by this procedure. LEVEL OF EVIDENCE: IV; retrospective, case series.
