Abstract:
Background:As the population is aging and indications are expanding, shoulder arthroplasty is becoming more frequent, especially bilateral staged replacement. However, surgeons are hesitant to use bilateral reverse prostheses due to potential limitations on activities of daily living.
Methods:This meta-analysis was conducted to compare bilateral anatomic to bilateral reverse shoulder implants. PubMed, Cochrane, and Google Scholar (pages 1–20) were searched until April 2023. The clinical outcomes consisted of postoperative functional scores (American Shoulder and Elbow Surgeons [ASES], Single Assessment Numeric Evaluation [SANE], Physical Component Score [PCS], Mental Component Score, and Simple Shoulder Test), pain, and range of motion (external rotation and forward elevation). Three studies were included in this meta-analysis.
Results:Bilateral anatomic implants had better postoperative functional outcomes and range of motion, but no significant difference was seen in postoperative pain when compared to the reverse prosthesis. Better ASES score, SANE score, and PCS as well as better external rotation and forward elevation were seen in the bilateral anatomic shoulder replacement group, but no significant difference in pain levels was seen between the two groups.
Conclusions:The results may be explained by the lower baseline seen in the reverse prosthesis group, which may be due to an older population and different indications. Nevertheless, more randomized controlled studies are needed to confirm these findings.Level of evidence: III.
