摘要

目的：本研究旨在确定因(1)髌骨疼痛或(2)髌骨不稳而接受胫骨结节截骨术(TTO)的患者在国际膝关节文献委员会(IKDC)和膝关节损伤与骨关节炎结果评分(KOOS)中的最小临床重要差异(MCID)：研究对象包括 2014 年 9 月至 2023 年 5 月期间在一家医疗机构接受胫骨结节截骨术（TTO）治疗的髌骨股骨疼痛或髌骨不稳的患者，由两名接受过运动医学研究培训的外科医生中的一位负责。术前和术后至少 1 年收集 IKDC 和 KOOS 评分。采用基于分布的方法计算MCID：共纳入了 77 名患者（82 个膝关节），中位年龄为 29.3 岁（四分位间距 [IQR]：22.2-36.3 岁），中位体重指数为 24.5 kg/m2 [IQR：22.3-28.3 kg/m2]。57例患者（74%）为女性，40例为右膝（49%）。获得IKDC和KOOS评分的中位时间分别为1.8年和1.7年。45名患者（46个膝关节）因髌骨股骨不稳接受了TTO治疗，32名患者（36个膝关节）因髌骨股骨疼痛接受了TTO治疗。接受 TTO 治疗髌骨股骨疼痛的患者，IKDC 的 MCID 为 11.5，KOOS 疼痛为 10.2，KOOS 症状为 10.1，KOOS 日常活动为 9.9，KOOS 运动为 14.2，KOOS QoL 为 14.2。对于因髌骨不稳而接受 TTO 的患者，IKDC 的 MCID 为 11.2，KOOS 疼痛的 MCID 为 10.1，KOOS 症状的 MCID 为 10.6，KOOS ADL 的 MCID 为 10.2，KOOS 运动的 MCID 为 16.0，KOOS QoL 的 MCID 为 13.2：我们确定了因髌骨股骨痛或髌骨不稳而接受TTO治疗的患者常用的患者报告结果测量指标的MCID：证据等级：二级。

Defining the minimal clinically important difference for IKDC and KOOS scores for patients undergoing tibial tubercle osteotomy for patellofemoral pain or instability

Purpose

The aim of the present study is to define the minimal clinically important difference (MCID) for International Knee Documentation Committee (IKDC) and Knee Injury and Osteoarthritis Outcome Score (KOOS) for patients undergoing tibial tubercle osteotomy (TTO) for either (1) patellofemoral pain or (2) patellar instability.

Methods

Patients undergoing TTO for either patellofemoral pain or patellar instability by one of two sports medicine fellowship-trained surgeons at a single institution between September 2014 and May 2023 were included in the study. IKDC and KOOS scores were collected preoperatively and minimum 1 year postoperatively. Distribution-based methods were used to calculate the MCID.

Results

Seventy-seven patients (82 knees) were included, with a median age of 29.3 years (interquartile range [IQR]: 22.2−36.3 years) and a median BMI of 24.5 kg/m² [IQR: 22.3−28.3 kg/m²]. Fifty-seven patients (74%) were female, and there were 40 right knees (49%). The median time to IKDC and KOOS score was 1.8 and 1.7 years, respectively. Forty-five patients (46 knees) underwent TTO for patellofemoral instability, and 32 patients (36 knees) underwent TTO for patellofemoral pain. The MCID was 11.5 for IKDC, 10.2 for KOOS pain, 10.1 for KOOS symptoms, 9.9 for KOOS ADL, 14.2 for KOOS sport and 14.2 for KOOS QoL for patients undergoing TTO for patellofemoral pain. The MCID was 11.2 for IKDC, 10.1 for KOOS pain, 10.6 for KOOS symptoms, 10.2 for KOOS ADL, 16.0 for KOOS sport and 13.2 for KOOS QoL for patients undergoing TTO for patellar instability.

Conclusion

We define the MCIDs for commonly used patient-reported outcome measures for patients undergoing TTO for either patellofemoral pain or patellar instability.
