Multiple Injections and Injections ≤6 Month Injections Before Rotator Cuff Repair May Increase the Risk of Retear: A Propensity Score-Matched Study.

ABSTRACT:

Background

The role of preoperative corticosteroid injections (CSIs) in rotator cuff repair (RCR) outcomes is controversial, with mixed evidence regarding their effect on tendon healing and postoperative recovery.

Purpose

To control for potential variables that may affect tendon healing and to explore the effect of CSIs on tendon healing and the difference in the effect of injection frequency and time interval on outcomes.

Study design

Cohort study; Level of evidence, 3.

Methods

This retrospective cohort study included 365 patients who underwent arthroscopic RCR between February 2021 and June 2023. Patients were categorized into CSI group (CSI group; n = 113) having a history of injections ≤1 year before surgery and control group (n = 252, 1 patient with bilate
