A number of reconstructive procedures are available for the management of hip osteoarthritis. Hip resurfacing arthroplasty is now an accepted procedure, with implant survivorship comparable to THA at up to 10 years' followup in certain series. Most reports focus on implant survivorship, surgeon-derived results, or complications. Fewer data pertain to patient-reported results, including validated measures of quality of life (QoL) and satisfaction and baseline measures from which to determine magnitude of improvement. Validated patient-reported results are essential to guide patients and surgeons in the current era of informed and shared decision making.
QUESTIONS/PURPOSES: We determined whether patients reported improvement in disease-specific, joint-specific, and generic QoL after hip resurfacing arthroplasty; whether patients were satisfied with the results of the procedure; and latest activity level and return to sport.
We retrospectively reviewed 127 patients (100 men, 27 women) who underwent 143 hip resurfacing procedures between 2002 and 2006. Mean patient age was 52 years. Patients completed the WOMAC, Oxford Hip Score, and SF-12 at baseline and again at minimum 2-year followup (mean, 2.5 years; range, 2-6 years). At latest followup, patients completed a validated satisfaction questionnaire and UCLA activity score.
All QoL scores improved (normalized to a 0-100 scale, where 100 = best health state). WOMAC improved from 46 to 95, Oxford Hip Score from 42 to 95, SF-12 (physical) from 34 to 54, and SF-12 (mental) from 46 to 56. Patient satisfaction score was 96. UCLA activity score was 8.
The majority of patients reported improvement in QoL, were very satisfied with their outcome, and returned to a high level of activity after hip resurfacing arthroplasty.

髋关节骨关节炎的治疗方法有很多种。髋关节表面置换术现在是一种被接受的手术，在某些系列研究中，在长达 10 年的随访中，其植入物存活率与全髋关节置换术相当。大多数报告都集中在植入物存活率、外科医生的结果或并发症上。关于患者报告的结果，包括经过验证的生活质量（QoL）和满意度以及基线测量数据，以确定改善的程度，数据较少。经过验证的患者报告结果对于指导患者和外科医生在当前知情和共享决策的时代至关重要。
问题/目的：我们确定了髋关节表面置换术后患者是否报告了疾病特异性、关节特异性和一般 QoL 的改善；患者对手术结果是否满意；以及最新的活动水平和重返运动情况。
我们回顾性分析了 2002 年至 2006 年间接受 143 例髋关节表面置换术的 127 例患者（100 例男性，27 例女性）。患者平均年龄为 52 岁。患者在基线时和至少 2 年的随访时（平均 2.5 年；范围，2-6 年）完成了 WOMAC、牛津髋关节评分和 SF-12。在最新的随访中，患者完成了一份经过验证的满意度问卷和 UCLA 活动评分。
所有 QoL 评分均有所改善（归一化为 0-100 分，其中 100 分为最佳健康状态）。WOMAC 从 46 分改善至 95 分，牛津髋关节评分从 42 分改善至 95 分，SF-12（物理）从 34 分改善至 54 分，SF-12（心理）从 46 分改善至 56 分。患者满意度评分为 96 分，UCLA 活动评分为 8 分。
大多数患者报告 QoL 得到改善，对手术结果非常满意，髋关节表面置换术后活动水平较高。
