Abstract：
BACKGROUND: This study evaluated the presence of the rotator cable intraoperatively and compared its prevalence according to both patient age and rotator cuff integrity. The study hypothesis was that the cable would be more prevalent in older patients and patients with partial-thickness tears.
METHODS: Patients who were undergoing shoulder arthroscopy and were aged at least 16 years were included in this study, whereas those who had a cuff tear of more than 1 tendon or who had a video with poor visualization of the rotator cuff insertion were excluded. Intraoperative videos were collected, deidentified, and distributed to 7 orthopedic surgeons to define rotator cable and cuff tear characteristics.
RESULTS: A total of 58 arthroscopic videos (average patient age, 46 years; range, 16-75 years) were evaluated. The observers were in the most agreement on identifying the presence of a cable, with a κ coefficient of 0.276. Patients with the rotator cable were significantly older than those without it (mean age, 52.1 years vs. 42.5 years; P = .008), and a positive and significant correlation was found between rotator cable presence and increasing patient age (r = 0.27, P = .04). A significant association was noted between tear degree and cable presence (P = .002). There was no significant association with cable presence in patients with a full-thickness tear.
CONCLUSIONS: In this study, an intraoperative analysis was performed to define the presence of the rotator cable and correlate this with both patient age and rotator cuff integrity. The hypothesis was confirmed in that patients older than 40 years had a significantly higher rotator cable prevalence.

摘要：
背景：这项研究在术中评估了转子电缆的存在，并根据患者年龄和肩袖完整性比较了其患病率。研究假设是，电缆在老年患者和部分厚度撕裂的患者中更为普遍。
方法：接受肩关节镜检查且年龄至少16岁的患者被纳入本研究。而袖带撕裂超过1根肌腱或视频显示肩袖插入的患者被排除在外.收集了术中视频，被取消身份，并分发给7名整形外科医生，以定义肩索和袖带撕裂的特征。
结果：总共58个关节镜视频（患者平均年龄，46年；范围，16-75岁）进行了评估。观察员对确定电缆的存在最一致，κ系数为0.276。有旋转电缆的患者明显比没有旋转电缆的患者年龄大（平均年龄，52.1年vs.42.5年；P=.008)，发现旋转电缆的存在与患者年龄的增加呈正相关且显着相关（r=0.27，P=.04）。注意到撕裂程度与电缆存在之间存在显着关联（P=0.002）。全层撕裂患者与电缆的存在没有显着关联。
结论：在这项研究中，我们进行了术中分析,以确定转子电缆的存在,并将其与患者年龄和肩袖完整性相关联.该假设得到了证实，因为40岁以上的患者的旋转电缆患病率明显更高。
