介绍一种关节镜下修复肩袖损伤的改良缝线桥技术（"悬索桥"技术），评估该技术在肩袖损伤修复中的临床效果，并与传统缝线桥缝合技术进行对比分析。

研究方案采用前瞻性对照设计，选取确诊为中型或大型肩袖损伤的患者作为研究对象，将其随机分为观察组与对照组以进行对比分析。在本研究中，观察组运用"悬索桥"缝合技术进行治疗，而对照组则采用传统缝线桥缝合方法。系统分析并记录两组受试者在手术过程中涉及的指标数据及其并发症的发生状况。分别对两组受试者术前与术后各时间节点的视觉模拟评分（visual analogue scale, VAS）、Constant评分、美国加州大学洛杉矶分校（University of California, Los Angeles, UCLA）评分、美国肩肘外科协会评分（American shoulder and elbow surgeon's form, ASES）进行比较分析，同时评估两组患者术后6个月、12个月肩关节活动度的变化情况，并进一步追踪患者术后12个月肩袖术后再撕裂率。

共纳入研究的患者共87例，其中观察组患者48例、对照组患者39例。通过数据分析，两组在手术时长、术中失血量以及术后住院天数方面差异均无统计学意义（P>0.05）。在手术过程中及术后早期，未发现血管神经损伤、伤口感染或锚钉脱落等不良后果。术后评估中，相比于术前，两组患者的疼痛VAS评分均显著下降（P<0.05），且在3个月、6个月及12个月随访期间，所有相关指标如Constant、UCLA和ASES评分均呈现持续改善趋势（P<0.05）。术后6个月和12个月随访期间，两组患者的肩关节前屈及外旋活动范围均显著提升，与术前相比有明显改善（P<0.05）。术后12个月随访，观察组肩袖再撕裂事件发生率仅为6.25%，而对照组则为20.51%，两组数据间比较差异具有统计学意义（P<0.05）。

对于中型及大型肩袖撕裂的修复，关节镜下"悬索桥"缝合技术与传统缝线桥技术均可取得良好的临床疗效，能有效恢复肩关节功能；相较于传统缝线桥技术，"悬索桥"技术可降低肩袖术后再次撕裂的风险。

Rotator cuff tear is a common condition of the shoulder joint. For patients who do not respond to conservative treatment, arthroscopic rotator cuff repair surgery becomes the main treatment option. However, retearing after rotator cuff suture remains a significant challenge for surgeons. This article describes a new technique for arthroscopic rotator cuff repair: the "Cable bridge" suture technique. Based on the suture principle of a cable bridge, this technique forms an integral structure by interlocking the different knots of the inner and outer rows of anchor nails.

To introduce an improved arthroscopic suture bridge technique for rotator cuff injury repair (Cable bridge), evaluate the clinical effect of this technique in rotator cuff injury repair, and conduct a comparative analysis with the traditional suture bridge technique.

The research protocol adopted a prospective controlled design. Patients with moderate or large rotator cuff injuries were selected as research subjects and randomly assigned to the observation and control groups for comparative analysis. In this study, the observation group received the "Cable bridge" technique, while the control group used the traditional suture bridge method. The system analyzed and recorded index data from the surgical process and the occurrence of complications in the two subject groups. The VAS, Constant, UCLA, and ASES scores of the two groups of subjects at each time point before and after the operation were compared and analyzed. Meanwhile, shoulder joint range of motion changes in the two patient groups at 6 and 12 months after the operation were evaluated, and the rotator cuff retear rate at 12 months was further tracked.

A total of 87 patients were included in the study, including 48 in the observation group and 39 in the control group. Data analysis revealed no significant differences between the two groups in operation duration, intraoperative blood loss, or postoperative hospital stay (P>0.05). During the operation and in the early postoperative period, no adverse events, such as vascular or nerve injury, wound infection, or anchor detachment, were observed. In the postoperative assessment, compared with those before the operation, the pain VAS scores of both groups of patients decreased significantly (P<0.05), and during the 3-month, 6-month, and 12-month follow-up periods, all related indicators, such as Constant, UCLA, and ASES scores, showed a continuous improvement trend (P<0.05). During the 6- and 12-month follow-up periods after the operation, forward flexion and external rotation range of motion of the shoulder joint in both groups increased significantly, showing noticeable improvement compared with preoperative values (P<0.05). At the 12-month follow-up after the operation, the incidence of rotator cuff retear events in the observation group was only 6.25%, while that in the control group was 20.51%. There was a statistically significant difference between the two groups of data (P<0.05) .

For the repair of medium and large rotator cuff tears, both the arthroscopic "Cable bridge" technique and the traditional suture bridge technique can achieve good clinical efficacy and effectively restore shoulder joint function. Compared with the traditional suture bridge technique, the "Cable bridge" technique can reduce the risk of the rotator cuff retearing after surgery.
