Background The advent of navigation in total knee arthroplasty (TKA) has generated interest in attempt to improve component positioning as desired and clinical outcomes. The aim of this study was to evaluate 90‐day complication and cost of navigation‐assisted TKAs (NTKA) compared to conventional TKAs (CTKA) using a national database. Methods A retrospective review of national database was conducted on all patients who underwent TKA from 2010 and 2017. The cohort was stratified into NTKA and CTKA subcohorts, excluding cases utilizing robotics. Results NTKA was associated with a significant decrease in 90‐day postoperative major and minor complications. NTKA was also associated with a decrease in 90‐day hospital utilization with lower rates of emergency department visits and readmissions. The cost of hospitalization and total 90‐day costs were lower in NTKA, with an average savings of $800. Conclusion The adoption of navigation in TKA is safe and efficaceous compared to CTKA.
