Purpose: Due to recent shifts in healthcare reimbursement models, more primary total hip arthroplasties (THAs) are now being performed in the outpatient setting. However, there is a lack of knowledge around the comparative outcomes of revision outpatient THA. Materials and Methods: Adults undergoing revision THA between 2010 and 2020 with 2-year follow-up data were identified on a large insurance claims database. Following stratification by inpatient versus outpatient revision THA, patients from both groups were matched 1:1 by demographics and revision characteristics. Ninety-day postoperative medical and 1- and 2-year postoperative surgical complications after matching were compared. Results: =0.023). Otherwise, the data for outpatient THA patients was not statistically different from inpatient THA patients across all studied complications. Conclusion: Outpatient revision THA may be a safe alternative to inpatient revision THA for carefully selected patients. Establishing patient- and case-specific parameters to optimize outcomes, satisfaction, safety, and value is critical.
