Santoro AJ, Post ZD, Thalody HS, Czymek MM, Ong AC, Ponzio DY. Outpatient total joint arthroplasty (TJA) gained favor during the COVID-19 pandemic. Our objective was to critically evaluate the safety and short-term outcomes of outpatient total hip arthroplasty (THA) and total knee arthroplasty (TKA) throughout the pandemic compared with pre-pandemic given their increased use. This was a retrospective review of 941 patients who underwent elective, outpatient TKA and THA at a single institution. Patients were divided into two cohorts: pre-pandemic (N=611) and pandemic (N=330). Data points included demographics, comorbidities, failure of same calendar day discharge (SCDD), and 90-day readmissions and re-operations. The pandemic cohort was older (61.0 vs 59.0 years; P=.001) and had a higher Charlson Comorbidity Index (2 vs 1; P=.004). There were no differences between the pandemic and pre-pandemic cohorts regarding SCDD failures (23.3% vs 21.9%; P=.623) and reoperations (4.2% vs 6.2%; P=.205). The pandemic cohort had a lower readmission rate (4.8% vs 8.2%; P=.056). Overall, patients who had failure of SCDD more commonly underwent TKA than THA (63.5% vs 36.5%; P
