Abstract：
OBJECTIVE: Pelvic compensation is common in femoroacetabular impingement (FAI) patients to reduce symptoms and increase range of motion. However, little attention was given to the postoperative clinical effect of pelvic compensation. Therefore, this study aims to compare the outcomes between pelvic compensation and normal pelvic position in femoroacetabular impingement (FAI) patients after hip arthroscopy.
METHODS: The retrospective study was conducted from January 2019 to June 2022, recruited consecutive patients who were diagnosed with FAI and received subsequent arthroscopic treatment. All patients completed an X-ray in the anterior-posterior standing position before and 4 weeks after surgery. Patients with pelvic compensation were compared with those who did not. Functional outcomes included hip disability and osteoarthritis outcome score (HOOS), modified Harris (mHHS) score, and lower-extremity activity scale (LEAS). Secondary outcomes included the EuroQol Five Dimensions Questionnaire (EQ-5D) and patient satisfaction. The intraclass correlation coefficient (ICC) was used to analyze interobserver and intraobserver reliability.
RESULTS: Ninety patients with a mean age of 39.40 years were included in the study. No significant compensation changes were noted within groups after the elimination of impingement. The functional scores showed no significant difference between groups (p(HOOS) = 0.352, p(mHHS) = 0.183, p(LEAS) = 0.865). The EQ-5D revealed statistically better performance in usual activities in the compensatory group (p = 0.044). There are no significant between-group differences in patients\' satisfaction evaluations.
CONCLUSIONS: As assessed by Patient-Reported Outcome Measures (PROMs), patients with compensatory pelvic tilt demonstrated similar clinical outcomes without extra adverse events to patients with normal pelvic positioning in short-term follow-ups. Furthermore, compensatory pelvic tilt did not significantly enhance the range of motion or functional outcome at short-term follow-ups.

摘要：
目的：骨盆代偿在股骨髋臼撞击（FAI）患者中很常见，以减轻症状并增加活动范围。然而,术后盆腔代偿的临床效果关注较少。因此,本研究旨在比较股骨髋臼撞击(FAI)患者在髋关节镜检查后骨盆代偿和正常骨盆位置的结果.
方法：回顾性研究于2019年1月至2022年6月进行，招募了诊断为FAI并接受后续关节镜治疗的连续患者。所有患者在手术前和手术后4周完成了前后站立位的X射线检查。将有骨盆代偿的患者与没有骨盆代偿的患者进行比较。功能结果包括髋关节残疾和骨关节炎结果评分（HOOS），改良哈里斯（mHHS）评分，和下肢活动量表（LEAS）。次要结果包括EuroQol五维问卷（EQ-5D）和患者满意度。组内相关系数（ICC）用于分析观察者间和观察者内的可靠性。
结果：90例平均年龄39.40岁的患者被纳入研究。消除撞击后，组内未发现明显的补偿变化。组间功能评分无显著差异(p(HOOS)=0.352,p(mHHS)=0.183,p(LEAS)=0.865)。EQ-5D显示代偿组的常规活动在统计学上表现更好（p=0.044）。患者满意度评价无显著组间差异。
结论：根据患者报告的结果指标（PROM）评估，在短期随访中,与骨盆位置正常的患者相比,代偿性骨盆倾斜的患者表现出相似的临床结局,没有额外的不良事件.此外，在短期随访中,代偿性骨盆倾斜并未显著增强运动范围或功能结局.
