Article Abstract

Reverse shoulder arthroplasty (RSA) will soon reach its 20-year anniversary in the United States and has now become the most performed shoulder arthroplasty in the United States. The evolution from Grammont style implants to lateralized designs continues to generate debate as comparable outcomes have been reported with both types of systems. While early literature focused on fixation and expanded indications, recent studies have evaluated component design and position and their effect on functional outcomes and complications. The purpose of this article was to provide a synopsis of design rationales of current RSA prostheses and review outcomes related to RSA design and position.
