Recent literature has called into question the safety of steroid injections before shoulder surgery due to increased infections and revisions.

This study aimed to determine the impact of ipsilateral injections on clinical outcomes following shoulder arthroplasty (SA).</p></div><div><h3>Methods</h3><p>A retrospective study was performed on patients who underwent SA by a single fellowship-trained orthopedic surgeon from 2017 to 2021. Patients were divided into two cohorts based on preoperative corticosteroid injection: (1) injection group (IG) and (2) no injection (control group (CG)). The IG was further stratified based on number of injections (1 vs. ≥2 injections) and timing of injections relative to surgery (&lt;3 months, 3-12 months, and &gt;12 months). Patient-reported pain and satisfaction, simple shoulder test, shoulder pain and disability index, visual analog scale for pain, University of California-Los Angeles score, American Shoulder and Elbow Surgeons score, Constant-Murley score, range of motion, complications, and reoperations were collected preoperatively and at final follow-up.
