Subacromial decompression was performed arthroscopically on 65 patients who were evaluated two to five years after the procedure. None had full thickness rotator cuff tears. Patients with partial thickness cuff tears were included in this study in order to allow comparison of arthroscopic acromioplasty with open acromioplasty for stage II impingement. On the UCLA shoulder rating scale, 89% of the cases in this study achieved a satisfactory result. These results compare favourably with those reported following open acromioplasty. The arthroscopic procedure is technically demanding. When properly performed in patients with appropriate indications, hospitalisation is brief, return to activities is rapid, there is little risk of deltoid muscle complications, and the results are lasting.
对65例患者进行了关节镜下肩峰下减压术，并在术后两到五年对他们进行了评估。所有患者均无肩袖全层撕裂。本研究纳入了部分厚度肩袖撕裂的患者，以便比较关节镜下肩峰成形术与开放性肩峰成形术治疗Ⅱ期撞击综合征的效果。根据加州大学洛杉矶分校（UCLA）肩关节评分量表，本研究中89%的病例取得了满意的结果。这些结果与开放性肩峰成形术后报告的结果相比更具优势。关节镜手术技术要求较高。在有适当适应证的患者中正确实施该手术时，住院时间短，恢复活动快，三角肌并发症风险小，且效果持久。
