Mehta B, Ho K, Bido J, et al. - This study was carried out to assess bilateral total knee arthroplasty (BTKA) vs unilateral TKA (UTKA) utilization and in-hospital complications comparing African Americans (AAs) and Whites. Researchers performed a retrospective analysis including patients ≥ 50 years who had undergone elective primary TKA, National Inpatient Sample - Healthcare Cost and Utilization Project database (2007-2016) was applied. They calculated variations in temporal trends in utilization and major in-hospital complication rates of BTKA vs UTKA comparing AAs and Whites. Researchers conducted multivariable logistic regression models to evaluate racial variations in trends adjusting for individual-, hospital- and community-level variables. An estimated 276,194 BTKA and 5,528,429 UTKA were performed in the US. The outcomes of this study demonstrate that the utilization of BKTA was higher in Whites in comparison with AAs in this nationwide sample of patients from 2007-2016 who had undergone total knee arthroplasty. For BTKA, this pattern was not consistent, while AAs have consistently higher in-hospital complication rates in UTKA over the time period.
