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.
