Corticosteroid Injections May Increase Retear and Revision Rates of Rotator Cuff Repair: A Systematic Review.

Purpose: To synthesize the clinical outcome data of preoperative and postoperative corticosteroid injections (CIs) and their effect on rotator cuff repairs (RCRs).

Methods: A systematic review was performed to identify studies that reported the results or clinical outcomes of RCRs in patients receiving either preoperative or postoperative CIs. The searches were performed using MEDLINE, Google Scholar, and Embase, and studies were chosen following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines.
