The aim of this study was to investigate how the critical shoulder angle (CSA) and acromion index (AI) affect the outcome of arthroscopic rotator cuff tear (RCT) repair.
A total of 287 patients, who underwent arthroscopic surgery due to degenerative rotator cuff tear, were evaluated. The Constant Shoulder Score (CSS), Oxford Shoulder Score (OSS) and Visual Analogue Scale (VAS) were evaluated preoperatively and postoperatively. The AI and CSA were measured on true anteroposterior shoulder radiographs. The patients were separated into two groups according to their CSA and AI values (control group ≤ 38°, increased CSA > 38°, and control group ≤ 0.7, increased AI > 0.7). The relationship between CSS, OSS and VAS was examined in all the groups.
The evaluation was made of a total of 287 patients with a mean age of 60.29 ± 8.55 years. The mean duration of follow-up of the patients was 34.00 ± 18.97 months (range 12-80 months). There was a statistically significant difference between the preoperative and postoperative clinical scores of the patients (< 0.05). No relationship was determined between CSA, AI and CSS, OSS or VAS during follow-up (> 0.05). The interobserver ICC for CSA and AI were determined to be 0.962 and 0.967, respectively (95% CI) indicating a high correlation (< 0.001).
CSA and AI do not affect functional outcomes in the postoperative period, so they are not significant at the time of degenerative arthroscopic rotator cuff repair decisions.
本研究旨在探讨临界肩角（CSA）和肩峰指数（AI）如何影响关节镜下肩袖撕裂（RCT）修复的结果。
对287例因退行性肩袖撕裂接受关节镜手术的患者进行评估。术前和术后评估Constant肩关节评分（CSS）、牛津肩关节评分（OSS）和视觉模拟量表（VAS）。在肩关节正位X线片上测量AI和CSA。根据患者的CSA和AI值将其分为两组（对照组≤38°，CSA增加组>38°，对照组≤0.7，AI增加组>0.7）。在所有组中检查CSS、OSS和VAS之间的关系。
共评估了287例患者，平均年龄为60.29±8.55岁。患者的平均随访时间为34.00±18.97个月（范围12 - 80个月）。患者术前和术后临床评分之间存在统计学显著差异（<0.05）。随访期间未确定CSA、AI与CSS、OSS或VAS之间存在相关性（>0.05）。CSA和AI的观察者间组内相关系数分别确定为0.962和0.967（95%CI），表明相关性较高（<0.001）。
CSA和AI在术后不影响功能结果，因此在退行性关节镜下肩袖修复决策时它们并不重要。
