Improvements in pain, function, and patient satisfaction are used to evaluate the outcomes of hip arthroscopic surgery.
To identify correlations between the visual analog scale (VAS) score for pain and patient satisfaction with 4 commonly used patient-reported outcome (PRO) scores to determine to what extent changes in these 2 parameters are reflected in each of the PRO scores.
Cohort study (diagnosis); Level of evidence, 3.
Patients undergoing hip arthroscopic surgery between February 2008 and February 2013 were assessed prospectively before surgery, at 3 months, and annually thereafter with the modified Harris Hip Score (mHHS), Nonarthritic Hip Score (NAHS), Hip Outcome Score-sports-specific subscale (HOS-SSS), and Hip Outcome Score-activities of daily living (HOS-ADL). Patients were also assessed using a 10-point VAS for pain and queried for satisfaction at the same time points ("0" indicated no pain, and "10" indicated complete satisfaction with surgery). The VAS score and patient satisfaction were correlated with changes in the 4 PRO scores.
During the study period, 1417 patients underwent hip arthroscopic surgery, of whom 1137 patients had 2-year postoperative PRO scores after primary surgery. There was a significant improvement in all PRO scores at 2-year follow-up. The mean improvements in mHHS, NAHS, HOS-ADL, and HOS-SSS scores were 16.7, 21.6, 19.7, and 22.7 points, respectively. The mean improvement in the VAS score was 2.9 points. Mean patient satisfaction at 2-year follow-up was 7.74 (of 10). There was a statistically significant correlation between the VAS and patient satisfaction scores and changes in each of the 4 PRO scores. The strength of the correlation was moderate.
This study demonstrated a moderate correlation between the VAS and patient satisfaction outcomes and changes in 4 commonly used PRO scores in hip arthroscopic surgery (mHHS, HOS-ADL, HOS-SSS, and NAHS). In addition to several PRO instruments, a VAS for pain and patient satisfaction may add to the overall assessment of the efficacy of hip arthroscopic surgery.
疼痛、功能及患者满意度的改善情况用于评估髋关节镜手术的疗效。
确定疼痛视觉模拟量表（VAS）评分与患者满意度之间的相关性，并与4种常用的患者报告结局（PRO）评分进行比较，以确定这两个参数的变化在每种PRO评分中得到反映的程度。
队列研究（诊断）；证据等级，3级。
对2008年2月至2013年2月期间接受髋关节镜手术的患者在术前、术后3个月及之后每年进行前瞻性评估，采用改良Harris髋关节评分（mHHS）、非关节炎髋关节评分（NAHS）、髋关节结局评分-运动特定子量表（HOS-SSS）和髋关节结局评分-日常生活活动（HOS-ADL）。同时使用10分制VAS评估患者疼痛情况，并询问患者在相同时间点的满意度（“0”表示无疼痛，“10”表示对手术完全满意）。将VAS评分和患者满意度与4种PRO评分的变化进行相关性分析。
在研究期间，1417例患者接受了髋关节镜手术，其中1137例患者在初次手术后有2年的PRO评分。在2年随访时，所有PRO评分均有显著改善。mHHS、NAHS、HOS-ADL和HOS-SSS评分的平均改善分别为16.7分、21.6分、19.7分和22.7分。VAS评分的平均改善为2.9分。2年随访时患者的平均满意度为7.74分（满分10分）。VAS评分和患者满意度与4种PRO评分的变化之间存在统计学显著相关性。相关性强度为中等。
本研究表明，在髋关节镜手术中，VAS评分与患者满意度结局以及4种常用PRO评分（mHHS、HOS-ADL、HOS-SSS和NAHS）的变化之间存在中等相关性。除了几种PRO工具外，疼痛VAS评分和患者满意度可能会增加对髋关节镜手术疗效的整体评估。
