Abstract

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.
