To determine the respective percent thresholds for achieving the maximal outcome improvement (MOI) for the modified Harris Hip Score (mHHS), the Non-Arthritic Hip Score (NAHS), the Hip Outcome Score-Sports Subscale (HOS-SSS), the visual analog scale (VAS) for pain, and the International Hip Outcome Tool-12 (iHOT-12) that were associated with satisfaction following revision hip arthroscopy, and to identify predictors for achieving the MOI.
An anchor question was provided to patients who underwent revision hip arthroscopy between April 2017 and July 2020. Patients were included for the final analysis if they answered the anchor question and had minimum 2-year follow-up. Receiver operating characteristic analysis was used to determine the thresholds for the percentage of the MOI predictive of satisfaction. A P-value of < .05 was considered significant.
In total, 318 patients underwent revision hip arthroscopy. Of those patients, 292 (91.8%) had minimum 2-year follow-up. Of this cohort, 68 answered the anchor question, with 49 (72.1%) female and 19 (27.9%) male patients. The mean age, and body mass index time were 32.9 ± 13 years and 25.4 ± 5.1, respectively. It was determined that 42.1%, 50%, 48.1%, 50%, and 50% of MOI were the thresholds for maximal predictability of satisfaction for mHHS, NAHS, HOS-SS, VAS for pain, and the iHOT-12, respectively. The presence of unaddressed subspine impingement was a significant predictor for achieving the MOI threshold for the VAS (odds ratio 1.40; 95% confidence interval 1.00-1.95; P = 0.0273).
Following revision hip arthroscopy, the percent thresholds for achieving the MOI at a minimum 2-year follow-up for the mHHS, NAHS, HOS-SS, VAS for pain, and iHOT-12 were 42.1%, 50%, 48.1%, 50%, and 50.9%, respectively. Addressing residual subspine impingement was identified as significant positive predictor for achieving the MOI.

确定改良 Harris 髋关节评分（mHHS）、非关节炎髋关节评分（NAHS）、髋关节结局评分-运动亚量表（HOS-SSS）、疼痛视觉模拟评分（VAS）和国际髋关节结局工具-12 （iHOT-12）在髋关节镜翻修后与满意度相关的达到最大结局改善（MOI）的百分比阈值，并确定达到 MOI 的预测因素。
为 2017 年 4 月至 2020 年 7 月期间接受髋关节镜翻修的患者提供一个锚定问题。如果患者回答了锚定问题并进行了至少 2 年的随访，则将其纳入最终分析。使用受试者工作特征分析确定预测满意度的 MOI 百分比的阈值。P 值<0.05 被认为具有统计学意义。
共有 318 例患者接受了髋关节镜翻修。其中 292 例（91.8%）进行了至少 2 年的随访。在这一组中，有 68 名患者回答了锚定问题，其中 49 名（72.1%）为女性，19 名（27.9%）为男性。平均年龄和体重指数分别为 32.9±13 岁和 25.4±5.1。结果确定，mHHS、NAHS、HOS-SS、疼痛 VAS 和 iHOT-12 的 MOI 分别达到 42.1%、50%、48.1%、50%和 50%时，预测满意度的可预测性达到最大值。未解决的小转子下撞击是达到 VAS 最大预测值的 MOI 阈值的显著预测因素（优势比 1.40；95%置信区间 1.00-1.95；P=0.0273）。
在髋关节镜翻修后，mHHS、NAHS、HOS-SS、疼痛 VAS 和 iHOT-12 达到 2 年最低随访 MOI 的百分比阈值分别为 42.1%、50%、48.1%、50%和 50.9%。解决残余小转子下撞击被确定为达到 MOI 的显著阳性预测因素。
