Background: Despite known surgical volume reductions in 2020 during the height of COVID-19 pandemic, no study has fully quantified impact pandemic on number elective inpatient total hip (THA) and knee arthroplasty (TKA) cases. The purpose present was to analyze THA TKA case volumes United States pandemic. Methods: Premier Healthcare Database utilized identify adults undergoing primary or from January 2017 December 2020. National Inpatient Sample cross-referenced provide nationwide representative sampling weights. Patients revision joint (TJA) non-elective surgery were excluded. Two quantitative models created both databases estimate TJA Descriptive statistics report monthly changes utilization throughout Univariate analyses performed compare differences between subgroups. Results: From 2019, it estimated that 1,006,000 TJAs (64.2% 35.8% THA) annually. In 2020, an 526,000 538,000 cases (62.0% 38.0% performed, representing a 46.5% 47.7% decrease prior 3-year average. Moreover, for April 1.9% average month through 2019. Subsequently, May June increased compared with those months There then July, corresponding “second wave” COVID-19, followed by additional steady decline December, “third wave.” Finally, represented only 41.0% Conclusions: midst approximately 3 previous years. effects persisted end year, decreased
