Bilateral Simultaneous Versus Staged Total Knee Replacement: A Comparison of Complications and Mortality

Background The purpose of this study is to compare the complications and mortality between bilateral simultaneous total knee replacement (BTKR-Simultaneous) and bilateral staged TKR (BTK-Staged) while adjusting for differences in patient, surgeon and hospital characteristics.

description Background The purpose of this study is to compare the complications and mortality between bilateral simultaneous total knee replacement (BTKR-Simultaneous) and bilateral staged TKR (BTK-Staged) while adjusting for differences in patient, surgeon and hospital characteristics. Methods An integrated healthcare system total joint registry was used to compare patients undergoing BTKR-Simultaneous to BTKR-Staged. For outcomes related to revision and infection the sample included 11,118 patients and for outcomes of death, acute myocardial infarction, stroke, and venous thromboembolism a subsample of 7,991 patients with comorbidity data was selected. Results Overall death and complications in both groups were rare. The complication rates for BTKR-Simultaneous and BTKR-Staged were comparable: Aseptic revision (1.17% vs 0.9%), septic revision/deep infection (0.8% vs 0.7%), death (0.28% vs 0.1%) and adverse events (2.49% vs 1.97%). In the adjusted models there were no significant differences in any of the outcomes between the two groups. Conclusion There is a lack of evidence to support superiority of either BTKR-Simultaneous or BTKR-Staged.
