New research demonstrates that there is a time-dependent relationship between shoulder injections and the risk of requiring a revision rotator cuff repair. The work has been presented at the American Orthopaedic Society for Sports Medicine's Specialty Day in New Orleans.

"As more patients elect to undergo a rotator cuff repair, surgeons may want to consider either delaying surgery or avoiding shoulder injections within 6 months to lower the risk of requiring a subsequent, revision rotator cuff repair," said lead researcher, Sophia A. Traven, MD from the Medical University of South Carolina in Charleston, South Carolina.

Traven and her team identified 4,959 patients who had an arthroscopic primary rotator cuff repair. Of these subjects, 553 required reoperation within the following three years and 392, or 70.9%, were for a revision rotator cuff repair. The mean age of those patients was 49.2 years and 53.6% were male. Patients who had an injection within 6 months were at a much higher risk of requiring a revision cuff repair within the following three years at 52.8%. Those who had an injection between 6-12 months before surgery had no increased risk compared to those that did not have an injection at all within the year preceding surgery.
