a, b: A female patient of gluteal fibrosis treated with arthroscopic tight fibrous band release. Before surgery, the patient was unable to cross or overlap his leg while sitting. c: The knees could not be kept together while sitting. d: Intraoperative photograph showing the important anatomic landmarks on the patient during surgery and the portals for arthroscopic gluteal muscle contracture (GMC) release. e: PP indicates posterior portal (the viewing portal), AP indicates anterior portal (the working portal). f: The picture suggests the intraoperative view under arthroscopy showing radiofrequency device cutting the tight fibrous band of gluteal fibrosis though anterior portal. g: Normal muscle fibers can be seen after tight fibrous band release. h, i: Ober’s sign was positive. j, k: Two days post-operative pictures, Ober’s sign was negative. l, m: At 2-month follow-up, the knees could be kept together while sitting (l) and the patient could sit with her legs crossed (m)
