The adoption of computer-assisted navigation technology has increased in both New York and Florida from 2010 to 2017. This is important because more patients are receiving CAKAs, which have been associated with improved mechanical alignment and the positioning of the prosthesis over conventional KAs.[1–7] However, the adoption rates of the different modalities of CAKA are unclear due to the overwhelming coding of the general code for computer-assisted surgery. Racial/ethnic and insurance disparities in CAKA rates were found in both New York and Florida, and these findings were more prominent in New York than Florida. Black and Hispanic patients in addition to Medicaid beneficiaries are less likely to receive this more advanced technology. Our findings have important implications for the uptake of this evolving technology and for improving access of disadvantaged populations.
