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.
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.
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/m [IQR: 22.3-28.3 kg/m]. 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.
We define the MCIDs for commonly used patient-reported outcome measures for patients undergoing TTO for either patellofemoral pain or patellar instability.

本研究的目的是确定接受胫骨结节截骨术（TTO）治疗（1）髌股关节疼痛或（2）髌骨不稳定的患者的国际膝关节文献委员会（IKDC）和膝关节损伤与骨关节炎疗效评分（KOOS）的最小临床重要差异（MCID）。
纳入2014年9月至2023年5月期间在单一机构由两名接受过运动医学专科培训的外科医生之一进行TTO治疗髌股关节疼痛或髌骨不稳定的患者。术前及术后至少1年收集IKDC和KOOS评分。采用基于分布的方法计算MCID。
纳入77例患者（82膝），中位年龄29.3岁（四分位间距[IQR]：22.2 - 36.3岁），中位体重指数为24.5kg/m²（IQR：22.3 - 28.3kg/m²）。57例患者（74%）为女性，右膝40例（49%）。IKDC和KOOS评分的中位时间分别为1.8年和1.7年。45例患者（46膝）因髌骨不稳定接受TTO，32例患者（36膝）因髌股关节疼痛接受TTO。接受TTO治疗髌股关节疼痛的患者，IKDC的MCID为11.5，KOOS疼痛为10.2，KOOS症状为10.1，KOOS日常生活活动（ADL）为9.9，KOOS运动为14.2，KOOS生活质量（QoL）为14.2。接受TTO治疗髌骨不稳定的患者，IKDC的MCID为11.2，KOOS疼痛为10.1，KOOS症状为10.6，KOOS ADL为10.2，KOOS运动为16.0，KOOS QoL为13.2。
我们确定了接受TTO治疗髌股关节疼痛或髌骨不稳定的患者常用的患者报告结局指标的MCID。
