Outpatient total shoulder arthroplasty in the ambulatory surgery center: a comparison of early complications in patients with and without glenoid bone loss.

Background: The purpose of this study is to compare the 90-day complications and readmission rates between patients undergoing total shoulder arthroplasty (TSA) in an ambulatory surgery center (ASC) with glenoid bone loss requiring an augmented glenoid component compared to patients without bone loss.

Methods: This is a retrospective cohort study of patients undergoing outpatient TSA at an ASC (2018-2021). Readmission, direct transfer, and complications were recorded.
