Orthopaedic Surgery

Navigation vs. robotics

Navigation systems deliver both clinical and economic advantages.

In total knee arthroplasty (TKA), computer-navigated procedures are becoming the dominant approach. These procedures are increasingly being found to be more advantageous than conventional operations. Not only patient satisfaction is generally higher, the precision of the implantations is greater. At the same time, the rate of complications is low as is the cumulative rate of revision. Robotic surgical systems are also becoming more and more important. In contrast to navigation systems, robotic systems execute actual steps of the operation – for example, skin incisions. Looking at all of the available evidence, robotic systems cannot yet provide the optimal combination of clinical and economic benefits that are currently available with navigation systems.
