The aim of this study was to evaluate the short term results of arthroscopic release for a stiff shoulder. Thirteen shoulders of twelve patients who underwent arthroscopic release for the stiff shoulder were studied. There were seven males and five females. The average age at operation was fifty-one point three years old (range: twenty-two-sixty-eight years old). There were frozen shoulders in six shoulders, a posttraumatic contracture in one shoulder, postoperative contractures in two shoulders, and contracture with rotator cuff tears in four shoulders. The mean duration of follow-up was twenty-four months (twelve-sixty months). The postoperative results were evaluated as JOA score, range of motion, visual analog pain scale (VAS), and satisfaction with the operation. The average JOA score improved from 57.2 points preoperatively to 85.5 points one year after operation. The average flexion was 94°preoperatively,15°intraoperatively and152°one year after the operation. The average external rotation was 16°,58°, and 49°respectively. VAS of night pain and motion pain improved.11 patients were satisfied with the surgery. Arthroscopic release for a stiff shoulder might be an effective procedure.
