Introduction: The purpose of this review is to outline some of the major considerations when transitioning to performing total hip and knee arthroplasty in the out- patient setting. The review will discuss patient selections, peri-operative management pathways, and outcomes related to outpatient total joint arthroplasty (TJA).
Patient selection: Appropriate patient selection is key to successful outpatient TJA. Multiple indices have been proposed to estimate patient risk before undergoing outpatient TJA. Perioperative Management: In order to provide a successful outpatient TJA experience, pre-operative education class and physical therapy session can set expectations and prepare the patient for the post-operative recovery at home. Specific anesthesia techniques focus on regional blocks, multi-modal pain control, and reduction of post-operative nausea and vomiting and rapid recovery protocols have been developed to provide early mobilization and physical therapy.
Outcomes: Nationwide analyses have found improved complication rates ranging from 1.3%-3% in outpatient TJA group compared to 3%-12% in the inpatient TJA group. Financial analyses have found significant cost savings for outpatient TJA mostly related to reduction in surgical floor care.
Conclusion: Outpatient TJA has the potential to improve patient experience with cost savings and no increased risk of complications in the appropriately selected patient population.
