Can we accelerate rehabilitation following reverse shoulder arthroplasty? A systematic review

Background There is no consensus concerning the rehabilitation protocol following reverse shoulder arthroplasty. Several patients are expecting to be able to use their arms for sports or recreation shortly after their operation. Methods This review was designed as an intervention systematic review with narrative analysis. Authors searched English literature in PubMed and Embase databases from 1/1/1989 until July 2022. Controlled studies comparing rehabilitation protocols for patients undergoing reverse shoulder arthroplasty were included. Data quality was examined with the Cochrane risk of a bias assessment tool for randomized trials, the Methodological Index for Non-Randomized studies (MINORS) tool, as well as the Grading of Recommendations Assessment Development and Evaluation (GRADE) approach. Results Three studies were finally analyzed. At 3 months post-op, forward flexion was found to be significantly higher in the early rehabilitation group (140.5, 95% confidence intervals (CIs): 135.10–145.89; the delayed rehabilitation group mean was 131.24, 95% CI: 125.73–136.74; p = 0.019). Twelve months post-op, no significant difference in any clinical or patient-reported outcome was shown. More complications were reported in the 6 weeks-delayed rehabilitation group. Discussion Newer regimes permit immediate shoulder mobilization but may not be applied to every patient. The lack of strong evidence warrants the need for future controlled studies; subsequently, postoperative rehabilitation should be individualized.
