Overview

The goal of the study is to compare the efficacy, safety and costs of the NAVIO™ system with the conventional intramedullary alignment guide for total knee replacement in a clinical setting. The hypothesis is that total knee arthroplasty (TKA) with the use of NAVIO™ is at least as efficient and safe as TKA with the use of conventional intramedullary alignment guiding.
