Clinically important outcome assessment has been a point of increasing emphasis in the orthopaedic literature. The minimal clinically important difference, patient acceptable symptom state, and substantial clinical benefit are the most reported in the hip preservation literature. Maximal outcome improvement (MOI) is now also being reported; however, its relation to patients undergoing hip preservation surgery is not well understood. The threshold values that represented satisfaction with surgery were 54.8%, 52.5%, 55.5%, and 55.8% of the MOI for the modified Harris Hip Score, Nonarthritic Hip Score, visual analog scale score for pain, and International Hip Outcome Tool-12 score, respectively. Although the MOI is helpful for characterizing outcome improvement, established measures such as substantial clinical benefit may be better used to grade outcomes in patients with high preoperative function.
临床重要结局评估一直是矫形文献中越来越受关注的一点。在髋关节保护文献中，最小临床重要差异、患者可接受的症状状态和实质性临床获益是最常报道的。最大结局改善（MOI）现在也有报道；然而，其与接受髋关节保护手术的患者的关系尚不清楚。手术满意度的阈值值分别为改良 Harris 髋关节评分、非关节炎髋关节评分、疼痛视觉模拟评分和国际髋关节结局工具-12 评分的 MOI 的 54.8%、52.5%、55.5%和 55.8%。尽管 MOI 有助于描述结局改善，但诸如实质性临床获益等既定指标可能更适合用于对术前功能较高的患者进行结局分级。
