The modified Harris Hip Score (mHHS) is a validated and disease-specific instrument commonly used to assess outcomes in total hip arthroplasty (THA). The Patient-Reported Outcomes Measurement Information System (PROMIS) is a validated, computer adaptive testing (CAT)-based global health assessment tool. The authors' goal was to examine the correlation between PROMIS Pain Interference and Physical Function CATs and the mHHS in patients undergoing primary THA. All THAs were performed by 1 of 2 fellowship-trained dedicated total joint surgeons at 1 academic institution. Patients completed PROMIS and mHHS assessments preoperatively and at 3, 6, 12, and 52 weeks postoperatively. Descriptive statistics and Pearson correlation values were determined. A total of 48 patients were prospectively enrolled in the study. Preoperatively, mean total PROMIS score (Pain Interference and Physical Function) was 74.2 and mHHS was 50.8. Preoperatively, mean total PROMIS score showed a moderate correlation (r=0.56; P<.0001) with total mHHS. Postoperatively, mean total PROMIS score at 3, 6, 12, and 52 weeks was 82.4, 93.4, 100, and 100, respectively (all P<.01 vs baseline), and mHHS was 68.2, 81.1, 85.9, and 88.6, respectively (all P<.01). At 3, 6, 12, and 52 weeks postoperatively, a strong and consistent correlation was observed between the total PROMIS score and mHHS (r=0.74, 0.74, 0.73, and 0.80, respectively; all P<.0001). The PROMIS Pain Interference and Physical Function CATs accurately assessed preoperative pain and dysfunction, as well as clinical improvement following THA. Combined PROMIS Pain Interference and Physical Function is comparable to the mHHS when assessing outcome following THA for osteoarthritis. [Orthopedics. 2021;44(1):e19-e25.].
改良的 Harris 髋关节评分（mHHS）是一种经过验证的、针对特定疾病的工具，常用于评估全髋关节置换术（THA）的结果。患者报告的结果测量信息系统（PROMIS）是一种经过验证的、基于计算机自适应测试（CAT）的整体健康评估工具。作者的目标是研究接受初次 THA 的患者中，PROMIS 疼痛干扰和身体功能 CAT 与 mHHS 之间的相关性。所有 THA 均由 1 家学术机构的 2 名 fellowship培训的专门从事全关节置换术的外科医生中的 1 名进行。患者在术前以及术后 3、6、12 和 52 周时完成 PROMIS 和 mHHS 评估。确定了描述性统计数据和 Pearson 相关系数值。共有 48 例患者前瞻性纳入本研究。术前，平均总 PROMIS 评分（疼痛干扰和身体功能）为 74.2，mHHS 为 50.8。术前，总 PROMIS 评分与 mHHS 呈中度相关（r=0.56；P<.0001）。术后，第 3、6、12 和 52 周时的平均总 PROMIS 评分分别为 82.4、93.4、100 和 100（均 P<.01 与基线相比），mHHS 分别为 68.2、81.1、85.9 和 88.6（均 P<.01）。术后 3、6、12 和 52 周时，总 PROMIS 评分与 mHHS 之间观察到强而一致的相关性（r=0.74、0.74、0.73 和 0.80，均 P<.0001）。PROMIS 疼痛干扰和身体功能 CAT 准确评估了 THA 前的疼痛和功能障碍，以及 THA 后的临床改善。在评估骨关节炎患者 THA 后的结果时，PROMIS 疼痛干扰和身体功能联合评分与 mHHS 相当。[骨科。2021；44(1):e19-e25.]。
