Background: Outcomes following 1-surgeon single-anesthetic sequential bilateral total knee arthroplasty (seq-BTKA) compared to 2-surgeon single-anesthetic simultaneous bilateral total knee arthroplasty (sim-BTKA) are largely unknown. The current study compared revision rates and all-cause mortality following seq-BTKA vs sim-BTKA using data from the Australian Orthopedic Association National Joint Replacement Registry. Methods: Seq-BTKA and sim-BTKA procedures recorded within the registry between September 1, 1999 and December 31, 2018 were analyzed for subsequent revision and patient mortality. Cumulative percent revision and cumulative percent survival were determined using the Kaplan-Meier method. Revision and mortality rates for sim-BTKA and seq-BTKA were compared using Cox proportional hazards models, adjusting for age and gender. Results: Included in the analysis were 27,480 seq-BTKAs and 471 sim-BTKAs. There was no difference in the cumulative percent revision between the 2 groups (hazard ratio 1.23, 95% confidence interval 0.82-1.85). Cumulative percent patient survival was not significantly different between the 2 groups (hazard ratio 1.20, 95% confidence interval 0.93-1.54). Conclusion: Revision rates and mortality were similar for seq-BTKA and sim-BTKA. Investigation of additional outcomes such as complications not requiring revision, pain, function, and cost is required to comprehensively understand the relative merits of each procedure.
