Prospective Comparative Study of Preoperative Expectations and Postoperative Outcomes in Anatomic and Reverse Shoulder Arthroplasty

摘要

Background Compared with anatomic total shoulder arthroplasty (aTSA), reverse total shoulder arthroplasty (RTSA) is associated with lower preoperative and postoperative outcome scores and range of motion. It is unknown whether patients' preoperative expectations of surgery are lower in RTSA compared with aTSA. The purpose of this study was to assess preoperative patient expectations and postoperative outcomes in aTSA and RTSA.
