Background and Objectives: Few studies have investigated the socioeconomic factors associated with retear after rotator cuff repair. This study aimed to identify the risk factors, including socioeconomic factors, for rotator cuff retear in patients who underwent arthroscopic rotator cuff repair. Materials and Methods: This retrospective study included 723 patients diagnosed with full-thickness rotator cuff tears who underwent arthroscopic rotator cuff repair from March 2010 to March 2021. The outcome variable was rotator cuff retear observed on postoperative magnetic resonance imaging or ultrasonography. Sex, age, obesity, diabetes, symptom duration, and tear size were the independent variables. Socioeconomic variables included occupation, educational level, type of medical insurance, and area of residence. We compared patients with and without retear and estimated the effects of the independent factors on retear risk. Results: The mean age of the patients, symptom duration, and tear size were 62.4 ± 8.0 years, 1.8 ± 1.7 years, and 21.8 ± 12.5 mm, respectively. The age, type of medical insurance, diabetes, tear size, and symptom duration differed significantly between patients with and without retearing (p < 0.05). Age, occupation, type of medical insurance, diabetes, initial tear size, and symptom duration significantly affected the risk of retear. Patients who performed manual labor had a significantly higher retear rate (p = 0.005; OR, 1.95; 95% CI, 1.23–3.11). The highest retear risk was seen in patients with Medicaid insurance (p < 0.001; OR, 4.34; 95% CI, 2.09–9.02). Conclusions: Age, initial tear size, and symptom duration significantly affect retear risk after arthroscopic rotator cuff repair. Occupation and type of medical insurance were also risk factors for retear. Socioeconomically vulnerable patients may be at a greater risk of retear. Proactive efforts are required to expand early access to medical care.

非创伤性肩袖撕裂关节镜手术后撕裂的社会经济和其他危险因素

背景和目的：很少有研究调查与肩袖修复术后后退相关的社会经济因素。本研究旨在确定接受关节镜下肩袖修复术的患者肩袖再撕裂的危险因素，包括社会经济因素。材料和方法：这项回顾性研究纳入了 723 名诊断为全层肩袖撕裂的患者，他们于 2010 年 3 月至 2021 年 3 月期间接受了关节镜下肩袖修复术。结果变量是术后磁共振成像或超声检查中观察到的肩袖再撕裂。性别、年龄、肥胖、糖尿病、症状持续时间和泪液大小是自变量。社会经济变量包括职业、教育水平、医疗保险类型和居住地区。我们比较了有和没有再角膜的患者，并估计了独立因素对再角膜风险的影响。结果：患者的平均年龄、症状持续时间和撕裂尺寸分别为 62.4 ± 8.0 岁、1.8 ± 1.7 岁和 21.8 ± 12.5 毫米。有和没有再撕裂患者的年龄、医疗保险类型、糖尿病、泪液大小和症状持续时间存在显着差异（p < 0.05）。年龄、职业、医疗保险类型、糖尿病、初始撕裂大小和症状持续时间显着影响再眼动的风险。进行体力劳动的患者的延迟率显着较高（p = 0.005；OR，1.95；95% CI，1.23-3.11）。拥有医疗补助保险的患者的再治疗风险最高（p < 0.001；OR，4.34；95% CI，2.09–9.02）。结论：年龄、初始撕裂大小和症状持续时间显着影响关节镜下肩袖修复术后的再撕裂风险。职业和医疗保险类型也是退职的危险因素。社会经济弱势的患者可能面临更大的退学风险。需要积极努力扩大早期医疗服务范围。
