Aims The aims of this study were to validate the minimal clinically important difference (MCID) and patient-acceptable symptom state (PASS) thresholds for Western Ontario Shoulder Instability Index (WOSI), Rowe score, American Shoulder and Elbow Surgeons (ASES), and visual analogue scale (VAS) scores following arthroscopic Bankart repair, and to identify preoperative threshold values of these scores that could predict the achievement of MCID and PASS. Methods A retrospective review was conducted on 131 consecutive patients with anterior shoulder instability who underwent arthroscopic Bankart repair between January 2020 and January 2023. Inclusion criteria required at least one episode of shoulder instability and a minimum follow-up period of 12 months. Preoperative and one-year postoperative scores were assessed. MCID and PASS were estimated using distribution-based and anchor-based methods, respectively. Receiver operating characteristic curve analysis determined preoperative patient-reported outcome measure thresholds predictive of achieving MCID and PASS. Results MCID thresholds were determined as 169.6, 6.8, 7.2, and 1.1 for WOSI, Rowe, ASES, and VAS, respectively. PASS thresholds were calculated as ≤ 480, ≥ 80, ≥ 87, and ≤ 1 for WOSI, Rowe, ASES, and VAS, respectively. Preoperative thresholds of ≥ 760 (WOSI) and ≤ 50 (Rowe) predicted achieving MCID for WOSI score (p < 0.001). Preoperative thresholds of ≤ 60 (ASES) and ≥ 2 (VAS) predicted achieving MCID for VAS score (p < 0.001). A preoperative threshold of ≥ 40 (Rowe) predicted achieving PASS for Rowe score (p = 0.005). Preoperative thresholds of ≥ 50 (ASES; p = 0.002) and ≤ 2 (VAS; p < 0.001) predicted achieving PASS for the ASES score. Preoperative thresholds of ≥ 43 (ASES; p = 0.046) and ≤ 4 (VAS; p = 0.024) predicted achieving PASS for the VAS. Conclusion This study defined MCID and PASS values for WOSI, Rowe, ASES, and VAS scores in patients undergoing arthroscopic Bankart repair. Higher preoperative functional scores may reduce the likelihood of achieving MCID but increase the likelihood of achieving the PASS. These findings provide valuable guidance for surgeons to counsel patients realistically regarding their expectations.

术前患者报告的结果测量可预测关节镜 Bankart 修复术后的最小临床重要差异和患者可接受的症状状态。


目的 本研究的目的是验证西安大略省肩关节不稳定指数 （WOSI） 、 Rowe 评分、美国肩肘外科医生 （ASES） 和视觉模拟量表 （VAS） 评分的最小临床重要差异 （MCID） 和患者可接受的症状状态 （PASS） 阈值关节镜下 Bankart 修复术后，并确定这些评分的术前阈值，可以预测 MCID 和 PASS 的实现。方法 进行回顾性回顾在 2020 年 1 月至 2023 年 1 月期间接受关节镜 Bankart 修复的连续 131 例肩前不稳定患者。纳入标准要求至少发作一次肩关节不稳定，并且至少随访 12 个月。评估术前和术后 1 年评分。MCID 和 PASS 分别使用基于分布和基于锚点的方法进行估计。受试者工作特征曲线分析确定了预测达到 MCID 和 PASS 的术前患者报告结局测量阈值。结果 WOSI 、 Rowe 、 ASES 和 VAS 的 MCID 阈值分别确定为 169.6 、 6.8 、 7.2 和 1.1。WOSI、Rowe、ASES 和 VAS 的 PASS 阈值分别计算为≤ 480、≥ 80、≥ 87 和 ≤ 1。术前阈值 ≥ 760 （WOSI） 和 ≤ 50 （Rowe） 预测 WOSI 评分达到 MCID （p < 0.001）。术前阈值 ≤ 60 （ASES） 和 ≥ 2 （VAS） 预测 VAS 评分达到 MCID （p < 0.001）。术前阈值 ≥ 40 （Rowe） 预测达到 Rowe 评分 PASS （p = 0.005）。术前阈值 ≥ 50 （ASES;p = 0.002） 和 ≤ 2 （VAS;p < 0.001） 预测 ASES 评分达到 PASS。术前阈值为 ≥ 43 （ASES;p = 0.046） 和 ≤ 4 （VAS;p = 0。024） 预测 VAS 达到 PASS。结论 本研究确定了关节镜下 Bankart 修复术患者 WOSI 、 Rowe 、 ASES 和 VAS 评分的 MCID 和 PASS 值。较高的术前功能评分可能会降低达到 MCID 的可能性，但会增加达到 PASS 的可能性。这些发现为外科医生提供了有价值的指导，以就患者的期望提供现实的咨询。
