: Preoperative Patient-centric Predictors of Postoperative Outcomes in Patients Undergoing Arthroscopic Meniscectomy

The Patient-Reported Outcomes Measurement Information System (PROMIS) is a valid and efficient means of collecting patient outcomes in patients with meniscal tears. The studies purpose was to define the minimally clinical important difference (MCID) for PROMIS domains following meniscectomy procedures. Secondary aims included determining the role of pre-operative PROMIS computer adaptive test (CAT) scores in predicting achievement of MCID following meniscectomy. Patients undergoing arthroscopic meniscectomy who completed PROMIS CAT forms for physical function (PROMIS-PF), pain interference (PROMIS-PI), and depression (PROMIS-D), from July 2017 to July 2019, at a single institution were utilized. MCID was calculated according to the distribution methodology, and receiver operating characteristics (ROC) were utilized to determine if pre-operative scores were predictive of post-operative outcomes. A total of 135 patients met inclusion criteria. Postoperative PROMIS-PF (45.6), PROMIS-PI (54.6), and PROMIS-D (44.1) significantly improved 3 months after surgery (
