Endoscopic iliotibial band release in snapping hip

Several open surgical techniques have been used to treat recalcitrant cases of snapping iliotibial band with varying results. Recently, endoscopic techniques have become available. The purpose of this study was to investigate the results of a modified endoscopic iliotibial band release using a longitudinal retrospective case series. Fifteen patients (three men and 12 women) with symptomatic external snapping hip were treated with an endoscopic release of the iliotibial band. The average age was 25 years (range 16-37 years). The procedure was performed in the lateral decubitus position using two portals; the iliotibial band was transversally released using a radiofrequency hook probe. The mean follow-up period was 33.8 months (range 12-84 months). The snapping phenomenon was overcome in all the patients. The mean pre-op pain VAS score was 5.5 mm (range 5-7 mm) and the mean post-op pain VAS score was 0.53 mm (range 0-2 mm) with a statistically significant reduction with respect to the preoperative value (p<0.0001); sixty percent of the patients were pain-free. The mean postoperative Harris Hip Score was 97.5 (range 94-100). No revision procedures were indicated and all the patients returned to their previous level of activity. The mean patient satisfaction score was, on average, 9.3 mm (range 8-10 mm) on the VAS scale. No complications occurred. Endoscopic iliotibial band release is a safe and reproducible technique with excellent results in terms of snapping phenomenon resolution, patient satisfaction, and return to previous level of activity. After strenuous sporting activities 40% of patients complained of very slight pain. © 2013 Wichtig Editore.
