Robotics in revision knee arthroplasty: Solution, support tool or new source of complexity?

Robotic-assisted knee arthroplasty has gained popularity throughout the globe due to high accuracy of three-dimensional component placement. The next step in the utilization of robotic-assisted knee arthroplasty is its application in revision surgery or in complex primary cases with bony defects. This will be a challenge because bony defects and/or component malposition need to be taken into account when planning to achieve good outcomes. Three-dimensional planning can be utilized for appropriate component placement, while considering the placement of revision components, spacers, cones/sleeves and intramedullary stems. Improvement in surgical planning prior and during surgery using robotic assistance can help surgeons significantly during revision total knee arthroplasty procedures.
