The relationship of preoperative factors to patient-reported outcome in rotator cuff repair: a systematic review

Background: Understanding preoperatively available factors that predict valid, patient-reported outcomes following rotator cuff repair can assist clinicians and their patients in making an informed, shared-decision on rotator cuff repair, and assist in setting an evidence-based prognosis.Objectives: To perform a systematic review of the preoperative factors related to patient-reported outcome following rotator cuff repair.Methods: A systematic review of the literature was performed to identify studies analyzing the relationship of preoperative factors to valid, patient-reported outcome measures. To be included in the review, outcome had to be measured by at least one valid upper extremity or shoulder-specific patient-reported outcome.Results: Twenty-three studies met the criteria for inclusion. Of these, 15 studies scored 3 or less on a 7-point scale of study quality indicating a paucity of strong trials investigating these prognostic factors. Prognostic factors reviewed included age, sex, worker’s compen...
