BACKGROUND Subacromial decompression, that consists of the release of the coracoid-acromial ligament, subacromial bursectomy and anterior-inferior acromioplasty, has traditionally been performed in the management of this pathology. However, the purpose of subacromial decompression procedure is not clearly explained. Our reaserch aimed to analyse the differences among the outcomes of arthroscopic rotator cuff repair (RCR) made with suture anchors, with or without the subacromial decompression procedure. METHODS 116 shoulders of 107 patients affected by rotator cuff (RC) tear were treated with Arthroscopic RCR. In 54 subjectes, the arthroscopic RCR and the subacromial decompression procedure (group A) were executed, whereas 53 took only arthroscopic RCR (group B). Clinical outcomes were evaluated through the use of the modified UCLA shoulder rating system, Wolfgang criteria shoulder score and Oxford shoulder score (OSS). Functional outcomes were assessed utilizing active and passive range of motion (ROM) of the shoulder, and muscle strength. The duration of the follow up and the configuration of the acromion were used to realize the comparison between the two groups. RESULTS In patients with 2 to 5 year follow up, UCLA score resulted greater in group A patients. In subjectes with longer than five years of follow up, group B patients showed considerably greater UCLA score and OSS if related with group A patients. In subjectes that had the type II acromion, group B patients presented a significant greater strength in external rotation. CONCLUSION The long term clinical outcomes resulted significantly higher in patients treated only with RCR respect the ones in patients underwent to RCR with subacromial decompression.

进行和不进行肩峰下减压的关节镜下肩袖修复术是安全有效的：一项临床研究。

背景技术传统上已经在这种病理学的管理中进行了肩峰下减压，该肩峰减压包括喙突韧带的释放，肩峰囊切除术和前下肩峰成形术。但是，肩峰减压手术的目的尚未明确说明。我们的研究旨在分析采用或不采用肩峰下减压手术的缝合锚钉进行关节镜式肩袖修补术（RCR）的结果之间的差异。方法对107例肩袖撕裂症患者的116个肩部进行关节镜RCR治疗。在54名受试者中，进行了关节镜下RCR和肩峰下减压手术（A组），而53名仅接受了关节镜下RCR（B组）。通过使用改良的UCLA肩膀评分系统，Wolfgang标准肩膀评分和牛津肩膀评分（OSS）评估临床结果。利用肩膀的主动和被动运动范围（ROM）和肌肉力量评估功能结局。随访的持续时间和肩峰的形状被用来实现两组之间的比较。结果在随访2至5年的患者中，A组患者的UCLA评分更高。在随访时间超过五年的受试者中，如果与A组患者相关，则B组患者显示出明显更高的UCLA评分和OSS。在患有II型肩峰的受试者中，B组患者的外旋力量明显增强。
