Abstract:
OBJECTIVE:To compare the effectiveness of arthroscopic outside-in release for gluteal muscle contracture (GMC) in supine position versus lateral decubitus position.
METHODS:The clinical data of 34 GMC patients meeting selection criteria between January 2022 and May 2023 were retrospectively analyzed. Arthroscopic contracture band release was performed in the lateral decubitus position (lateral group, n=14) or the supine position (supine group, n=20). No significant difference ( P>0.05) was observed between groups in baseline data, including gender, age, body mass index, preoperative GMC functional quantitative score, modified Harris hip score (mHHS), visual analogue scale (VAS) pain score, and hip flexion/adduction range of motion (ROM). The total operation time, release procedure time, non-release procedure time, intraoperative blood loss, hospital stay, and postoperative complications were recorded and compared. Functional outcomes (GMC functional quantitative score, mHHS score, VAS score, hip flexion/adduction ROM) were evaluated preoperatively and at 3, 12, and 24 months postoperatively.
RESULTS:All incisions healed by first intention without major vascular or neurological complications. In the lateral group, 3 patients developed patchy bruising on bilateral buttocks and posterior thighs at 3 days after operation, which resolved after 2 weeks of ice packs and ultrasonic therapy. The supine group demonstrated significantly shorter total operation time, non-release procedure time, hospital stay, and reduced intraoperative blood loss versus the lateral group ( P<0.05). No significant difference was found in release procedure time ( P>0.05). All patients were followed up 24 months. Both groups showed significant improvements ( P<0.05) in mHHS score, GMC functional quantitative score, VAS score, and hip adduction/flexion ROM at all postoperative timepoints compared to preoperative values, with no significant intergroup differences ( P>0.05).
CONCLUSION:Both surgical positions effectively improve hip function in GMC patients. However, the supine position offers significant advantages over the lateral decubitus position in operation time, anesthesia management, intraoperative blood loss control, and reduced hospital stay.
