The purpose of this multicenter study was to evaluate any changes in the rates of 90-day PJI or 30-day SSI, including trends in microbiology of the infections, during the COVID-19 pandemic compared to the three years prior.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Patients and Methods:<\/jats:title>\n                    <jats:p>An Institutional Review Board-approved, multicenter, retrospective study was conducted with five participating academic institutions across two healthcare systems in the northeastern United States. Primary TJA patients from the years 2017\u20132019 were grouped as a pre-COVID-19 pandemic cohort and patients from the year 2020 were grouped as a COVID-19 pandemic cohort. Differences in patient demographics, PJI, SSI, and microbiology between the two cohorts were assessed.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>A total of 14,844 TJAs in the pre-COVID-19 pandemic cohort and 5,453 TJAs in the COVID-19 pandemic cohort were evaluated.

Larger national database studies may identify small but substantial differences in 90-day PJI and 30-day superficial SSI rates between these two time periods. Our data may support continued efforts to maintain high compliance with hand hygiene, use of personal protective equipment, and limited hospital visitation whenever possible.<\/jats:p>\n
