Comorbid Factors and Selection for Same-Day Total Joint Arthroplasty.

Given that the number of total joint arthroplasties (TJAs) performed worldwide is expected to continue to increase, and there are significant costs associated with these procedures, selecting candidates for same-day or 23-hour discharge is important in lowering costs and providing greater access. Younger, healthier patients are excellent candidates for same-day discharge after TJA. Preoperative medical assessment can help exclude patients who may not be candidates, such as patients with 1 or more comorbidities that increase the risk of intra- and postoperative complications and who may require a longer period of monitoring.
