Abstract
Purpose: To validate the Patient-Reported Outcomes Measurement Information System (PROMIS) physical function computer adaptive test (PF CAT) with current patient-reported outcome (PRO) instruments in patients with cartilage injuries of the knee. Methods: Patients scheduled for osteochondral autograft or allograft transplant, microfracture, autologous chondrocyte implantation, allograft cartilage resurfacing, and chondroplasty were prospectively enrolled in the study and completed PROMIS PF CAT, Knee Injury and Osteoarthritis Outcome Score (KOOS activities of daily living, pain, symptoms, sport, and quality of life), Short Form-36 Health Survey (SF-36 physical function [PF] and Physical Component Summary), and EuroQol-5 Dimension questionnaires. The Spearman correlation coefficient was used to compare instruments. Instrument correlations were defined as excellent (>0.7), excellent to good (0.61-0.69), good (0.4 to 0.6), and poor (<0.39), with significance defined as P < .05. Results: A total of 293 knees in 275 patients (54.5% male) undergoing 319 cartilage procedures were analyzed. The most commonly performed cartilage procedure was chondroplasty (n = 118; 37.0%), followed by microfracture (n = 100; 31.3%). The mean age was 34.0 +/- 14.7 and the mean body mass index was 30.0 +/- 6.9. The PROMIS PF CAT had an excellent correlation with the SF-36 PF (r = 0.819; P < .001), SF-36 Physical Component Summary (r = 0.766; P < .001), KOOS activities of daily living (r = 0.733; P < .001), KOOS Sport (r = 0.709; P < .001), and EuroQol-5 Dimension (r = 0.752; P < .001) instruments; an excellent-good correlation with the KOOS pain (r = 0.662; P < .001), and KOOS quality of life (r = 0.640; P < .001) scores; and a good correlation with the KOOS symptoms (r = 0.519; P < .001) scale. The PROMIS PF CAT had no floor or ceiling effects and the smallest question burden (mean 4.17 +/- 0.93 questions). Dimensionality analyses demonstrated that the smallest amount of unexplained variance was present in the PROMIS PF CAT (3.6%). Conclusion: The PROMIS PF CAT is an effective tool for preoperative outcome assessment in patients with cartilage defects of the knee. It correlates strongly with legacy PRO measures of physical function with no ceiling and floor effects and a minimal time burden for completion. Further study is warranted to determine postoperative performance and to evaluate the responsiveness of PROMIS to change within a patient.
