Excellent Correlation of the Patient-Reported Outcomes Measurement Information System Upper Extremity Score With Legacy Outcome Scores Preoperatively and at 1 Year After Arthroscopic Rotator Cuff Repair

PURPOSE: To assess the preoperative and postoperative performance of the Patient-Reported Outcomes Measurement Information System Upper Extremity (PROMIS-UE, version 2.0) outcome score in comparison to the American Shoulder and Elbow Surgeons (ASES) and Western Ontario Rotator Cuff Index (WORC) instruments in patients undergoing rotator cuff repair. METHODS: This prospective longitudinal study included 91 patients undergoing rotator cuff repair. Patients completed the PROMIS-UE, ASES, and WORC instruments preoperatively and postoperatively at 2 weeks, 6 weeks, 3 months, and 12 months. The Pearson correlation coefficient (r) between these tools was calculated at each time point. Correlations were graded as excellent (>0.7), excellent-good (0.61-0.7), good (0.4-0.6), or poor (
