Objective: This study aims to compare the clinical and radiographic outcomes of the tight-rope system versus internal fixation with a hook plate for treating grade III-VI acute acromioclavicular dislocation.

Methods: Relevant studies were identified by searching PubMed, Cochrane, and Google Scholar, from January 2017 to December 2023. The primary focus of the study revolved around evaluating various factors such as the Constant Score, University of California Los Angeles (UCLA) Shoulder Score, Visual Analogue Scale (VAS), coracoclavicular distance (CCD), and incidences of complications. The analysis involved determining the weighted mean difference (WMD) along with its corresponding 95 % confidence intervals (95 % CIs), or risk ratios (RR) with 95 % CIs to quantify the collected data.

Results: Eight studies comprising 484 participants were included. Significant differences were observed in the Constant-Murley score between groups. However, no disparities were found in UCLA scores, VAS scores, or CCD improvement. Subgroup analyses also yielded consistent results.

Conclusions: Both treatment modalities demonstrated similar clinical and radiographic efficacy in alleviating pain, enhancing acromioclavicular joint function, and correcting coracoclavicular distance. Nevertheless, the TightRope system exhibited additional advantages, including reduced reoperation rates and lower risk of subacromial distal clavicle osteolysis.

目的： 本研究旨在比较 Tight-Rope 系统与使用钩板内固定治疗 III-VI 度急性肩锁关节脱位的临床和放射学结局。

方法： 通过检索 PubMed、Cochrane 和 Google Scholar，从 2017 年 1 月到 2023 年 12 月确定了相关研究。本研究主要围绕 Constant Score、加州大学洛杉矶分校肩关节评分（UCLA 肩部评分）、视觉模拟量表 (VAS)、喙锁间距 (CCD) 和并发症发生率等各个因素进行评估。分析包括确定加权均差 (WMD) 及其相应的 95% 置信区间 (95% CI)，或风险比 (RR) 及其对应的 95% CI，以量化收集的数据。

结果： 共纳入了八项研究，涉及 484 名参与者。在 Constant-Murley 评分中观察到组间存在显著差异。然而，在 UCLA 评分、VAS 评分或 CCD 改善方面没有发现差异。亚组分析也得到了一致的结果。

结论： 两种治疗方法均表现出相似的临床和放射学疗效，包括减轻疼痛、改善肩锁关节功能以及校正喙锁间距。然而，TightRope 系统还显示了其他优势，例如再手术率降低及亚关节下锁骨骨溶解的风险较低。
