10-Year Survival of Navigated Versus Conventional TKAs: A Retrospective Study.

The computer-assisted navigation of total knee arthroplasty (TKA) offers a radiologically demonstrated higher precision of implantation than conventional implantation in relation to the axis alignment. The impact on long-term clinical outcomes is currently unknown. In 1999, 217 consecutive TKAs were performed in a total of 213 patients (113 navigated and 104 conventional).
