Abstract：
BACKGROUND: Arthroscopic surgery has been established as an efficacious intervention for the treatment of rotator cuff tears. The primary aim of this study was to analyze the modifications in the lateral acromial angle (LAA) subsequent to rotator cuff repair surgery using single-row rivet fixation and double-row rivet fixation techniques. Furthermore, we sought to investigate the influence of LAA on the prognosis of rotator cuff repair surgery.
METHODS: This observational study retrospectively enrolled 105 patients diagnosed with degenerative rotator cuff tears who underwent arthroscopic rotator cuff repair between 2016 and 2019. Following the exclusion of two patients with subscapularis or superior labrum anterior and posterior (SLAP) tears, as well as three patients who were lost to follow-up, a cohort of 100 patients was included for clinical and imaging evaluation. Among these individuals, 50 were assigned to the double-row repair group, whereas the remaining 50 comprised the single-row repair group. Bilateral shoulder magnetic resonance imaging (MRI) scans were conducted no less than 24 months post-surgery. Experienced arthroscopic surgeons, blinded to the LAA measurements, assessed the rotator interval (RI) using a control MRI. Functional assessment was performed using the University of California, Los Angeles (UCLA) quick disability of the shoulder and arm, shoulder and hand (qDASH) score. The Wilcoxon signed-rank test for dependent samples was employed to compare data between the pre- and post-intervention groups. Pearson correlation coefficients were calculated to evaluate the relationship between different parameters.
RESULTS: The study population consisted of 73 female patients and 27 male patients, with a mean age of 58.32 ± 5.29 years and a mean follow-up duration of 25.88 ± 8.11 months. Preoperatively, the mean LAA was 75.81° ± 11.28°, RI was 4.78 ± 0.62, UCLA score was 17.54 ± 2.44, and qDASH score was 2.45 ± 0.25. The average tear size was 8.95 ± 2.11 mm. A statistically significant difference in LAA was observed between the preoperative and postoperative measurements, with the double-row repair group exhibiting a greater LAA than the single-row repair group. Finally, a significant correlation was identified between LAA, RI, and qDASH scores after a 24-month follow-up period.
CONCLUSIONS: According to our findings, the utilization of double-row rivet fixation has a greater LAA angle than single-row rivet fixation. Moreover, this preservation of LAA is significantly associated with the functional recovery of the shoulder joint.

摘要：
背景：关节镜手术已被确立为治疗肩袖撕裂的有效干预措施。这项研究的主要目的是分析使用单排铆钉固定和双排铆钉固定技术进行肩袖修复手术后外侧肩峰角（LAA）的修改。此外，我们试图探讨LAA对肩袖修复手术预后的影响.
方法：这项观察性研究回顾性纳入了105例诊断为退行性肩袖撕裂的患者，这些患者在2016年至2019年间接受了关节镜肩袖修复。排除两名肩胛骨下或上唇前路和后路(SLAP)撕裂患者后，以及三名失去随访的患者，纳入一组100例患者进行临床和影像学评估.在这些人中,50人被分配到双排修复组，而其余50人组成单行修复组。手术后不少于24个月进行双侧肩部磁共振成像（MRI）扫描。经验丰富的关节镜外科医生，对左心耳测量视而不见，使用对照MRI评估旋转器间隔(RI)。使用加利福尼亚大学进行功能评估，洛杉矶（UCLA）快速残疾的肩膀和手臂，肩和手（qDASH）得分。采用依赖样本的Wilcoxon符号秩检验比较干预前后组的数据。计算皮尔逊相关系数以评估不同参数之间的关系。
结果：研究人群包括73名女性患者和27名男性患者，平均年龄58.32±5.29岁，平均随访时间25.88±8.11个月。术前,平均左心耳为75.81°±11.28°,RI为4.78±0.62，UCLA评分为17.54±2.44，qDASH评分为2.45±0.25。平均泪液大小为8.95±2.11mm。在术前和术后测量之间观察到LAA的统计学差异，双行修复组比单行修复组表现出更大的LAA。最后,LAA，RI,24个月随访后的qDASH评分。
结论：根据我们的发现，使用双排铆钉固定比单排铆钉固定具有更大的LAA角。此外，LAA的这种保留与肩关节功能恢复显著相关.
