Maintenance of Surgical Optimization in Total Joint Arthroplasty Patients.

Background: There are increased efforts to maximize medical optimization to improve the outcomes of total joint arthroplasty (TJA). However, there is a paucity of literature demonstrating that optimized parameters are maintained throughout the perioperative period.

Methods: A retrospective review of 877 elective TJA patients from 2015 to 2019 was conducted.

Thirty-Day Mortality and Complication Rates in Total Joint Arthroplasty After a Recent COVID-19 Diagnosis: A Retrospective Cohort in the National COVID Cohort Collaborative (N3C).

Background: The risk of postoperative complications in patients who had a positive COVID-19 test prior to a total joint arthroplasty (TJA) is unknown. The purpose of this investigation was to study the complications and mortality associated with a recent COVID-19 diagnosis prior to TJA.

Methods: Patients undergoing primary and revision total hip arthroplasties (THAs) or total knee arthroplasties (TKAs) were identified using the National COVID Cohort Collaborative (N3C) Data Enclave.
