Abstract
Background
Rotator cuff tears are a leading cause of shoulder pain and disability in adults. Arthroscopic rotator cuff repair (RCR) aims to improve function and reduce pain. The Patient-Reported Outcome Measurement Information System (PROMIS) Pain Interference (PI) assesses the impact of pain on daily life. This study aimed to identify preoperative predictors of PROMIS PI two years after RCR.Methods
Patients undergoing arthroscopic RCR from June 2015 to April 2022 were identified from a prospectively enrolled orthopaedic registry. Chart review of the electronic medical record was performed for demographic factors, surgical factors, and patients' Charlson Comorbidity Index (CCI). Patient-reported outcomes (PROs) were collected at baseline and two years postoperatively, including six PROMIS domains, American Shoulder and Elbow Surgeons score (ASES), numeric pain scales (NPS) of the operative shoulder and body, Tegner Activity Subscale (TAS), and Marx Activity Rating Scale of the upper extremity (MARS UE). Statistical analyses were conducted to identify significant predictors of two-year PROMIS PI scores and change in PROMIS PI from baseline.Results
Among 203 patients, 152 (75%) completed two-year PROs after RCR. On multivariable regression, higher preoperative ASES independently predicted better two-year PROMIS PI (Estimate -0.17, 95% CI -0.25 to -0.08, pConclusion
Better preoperative ASES scores independently predicted better two-year PROMIS PI, while worse preoperative PROMIS Depression, and higher CCI predicted worse two-year PROMIS PI after RCR. Preoperative assessment of these measures is a good indicator of postoperative pain and may inform preoperative counseling in patients undergoing arthroscopic RCR.Level of evidence
