Abstract

PURPOSE: To compare the use and responsiveness of Patient Reported Outcomes Measurement Information System (PROMIS) to legacy patient-reported outcome measures (PROMs) in patients undergoing hip arthroscopy for femoroacetabular impingement syndrome (FAIS) at 6-month follow-up.

METHODS: Data from patients who underwent primary hip arthroscopy with routine capsular closure between August 2018 and January 2019 for the treatment of FAIS were analyzed. Preoperative outcomes, 6-month postoperative outcomes, and demographics were recorded. Primary outcome measures included PROMIS Physical Function (PROMIS-PF), PROMIS Pain Interference (PROMIS-PI), and PROMIS Depression. The legacy PROMs included Hip Outcome Score Activities of Daily Living (HOS-ADL), Hip Outcome Score Sport Subscale (HOS-SS), and the international hip outcome tool 12 questions (iHOT-12). Floor and ceiling effects along with the responsiveness and Cohen's d effect size of each PROM tool were calculated.

RESULTS: Ninety-six patients with an average age and body mass index (BMI) of 32.4±11.9 years and 25.9±6.1 kg/m(2) respectively were included in the final analysis. All outcomes were significantly higher at 6 months compared to the pre-operative level (p<0.001) except for PROMIS Depression (p=0.873). PROMIS-PF demonstrated excellent correlation with HOS-SS (r=0.81; p<0.001), very good correlation with HOS-ADL (r=0.73; p<0.001), and good correlation with iHOT-12 (r=0.68; p<0.001). No floor was observed for any measure. The effect size was large for all outcomes, except PROMIS Depression (d=0.04), but largest for iHOT12 (d=1.87) followed by HOS-ADL (d=1.29). The iHOT-12 was more responsive than PROMIS-PI (RE=3.95), PROMIS-PF (RE=4.13), HOS-ADL (RE=2.26), and HOS-SS (RE=3.84). HOS-SS was similarly responsive to PROMIS-PI (RE=1.03) and PROMIS-PF (RE=1.08). However, PROMIS-PF was overall the least responsive.

CONCLUSIONS: In patients at 6 months postoperatively from hip arthroscopy for FAIS, iHOT-12 was the most responsive and had the largest effect size. In contrast, PROMIS-PF had a lower effect size compared with legacy hip-specific PROMs. Additionally, PROMIS-PF did not correlate as well with iHOT-12 compared with HOS-SS.

LEVEL OF EVIDENCE: Level IV, case series.
