Patient Characteristics and Surgical Start Time Affect Length of Stay Following Anterior Total Hip Arthroplasty.

Background: Currently, no consensus exists for selection criteria of appropriate candidates for outpatient total hip arthroplasty (THA). This study evaluates patient characteristics associated with same-day discharge, examined surgical start time's effect on rates of same-day discharge, and compares readmission and reoperation rates between groups.

Methods: All patients who underwent a THA by one surgeon at a single quaternary care hospital between February 2016 and May 2018 were captured.
