Inclusion criteria were patients presented positive preoperative signs, including squatting and crouching impairment, difficulty in crossing the legs, a positive Ober's sign, with or without clicking sounds during hip rotation. The annular release treatment was done around the greater trochanter, which has a sparse distribution of muscle and neuromuscular tissues. Arthroscopic observation and intraoperative physical examination were used to assess the adequacy of the release. Additionally, clinical assessments included the Gluteal Muscle Contracture Disability Scale (GDS), Visual Analogue Scale (VAS), and pain frequency, which were evaluated pre\u2010 and postoperatively. A paired Student's t\u2010test was applied to compare the GDS, VAS, and pain frequency scores before and after surgery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 22 patients were included in the final analysis, with an average follow\u2010up of 2\u2009years. All operations were successfully completed, with no intraoperative conversion to alternative surgical methods. After surgery, most patients achieved satisfactory postoperative outcomes; isolated limitations persisted in one patient who reported persistent squatting difficulty, and two patients continued to have trouble crossing their legs. The GDS score was 43.8\u2009\u00b1\u200913.3 preoperatively and 72.7\u2009\u00b1\u20099.6 at the final follow\u2010up, showing a statistically significant improvement (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.01).
