    IntroductionIn June 2020 when elective total knee arthroplasty (TKA) resumed after the initial COVID-19 surge, we adapted our TKA pathway focusing on a shorter hospitalization, increased home discharge, and use of post-discharge telemedicine and telerehabilitation. The purpose of this study was to evaluate if changes in postoperative care affected early TKA outcomes.Materials And MethodsFive hundred and fifty-four patients who underwent elective primary unilateral TKA for primary osteoarthritis between June and August 2020 (study group) were matched 1:1 for age, sex, body mass index, and Charlson comorbidity index with control patients who underwent surgery between August and November 2019. Study patients were discharged 25 h earlier on average compared to controls, more frequently on the same-day or postoperative day-1 (24.9% vs. 16.1%; p = 0.001), and more frequently home (97.3% vs. 83.8%; p < 0.001). Study patients used telemedicine (11.7% vs. 0%; p < 0.001) and telerehabilitation (19.7% vs. 2.5%; p < 0.001) at higher rates than controls. Generalized estimating equations, Mann-Whitney U, and Chi-Square tests were used to compare outcomes between groups including unscheduled office visits, ER visits, readmissions, Center for Medicare and Medicaid Services (CMS) complications, manipulation under anesthesia (MUA), and patient-reported outcomes measures (PROMs).ResultsRates of emergency room visits, readmissions, CMS complications, MUA, and improvements in PROMs were similar between cohorts. Study patients experienced higher rates of unscheduled outpatient visits (9.2% vs. 4.9%; p = 0.004), predominantly due to wound complications.ConclusionsA protocol implemented during the COVID-19 pandemic that leveraged a shortened hospitalization, higher rates of home discharge, and increased use of telemedicine and telerehabilitation was safe and effective.© 2022.
