“…Outpatient primary TJA has been adopted at a growing number of ambulatory surgical centers (ASCs) and hospital systems in the United States. Studies have demonstrated that with appropriate risk stratification and patient selection, and modern arthroplasty care pathways and perioperative protocols, outpatient primary TJA has outcomes equivalent or superior to inpatient primary TJA [ [11] , [12] , [13] , [14] , [15] , [16] , [17] , [18] , [19] , [20] ] More recently, early discharge following aseptic revision TJA has been investigated; however, only a few studies have been published to date, [ [21] , [22] , [23] , [24] ] with only 2 studies focused specifically on same-day discharge (SDD) [ 21 , 22 ]. As the trend toward outpatient primary and aseptic revision TJA accelerates, futher investigation is required to identify patient selection criteria and best perioperative practices to ensure patient safety.…”
