Robotic-Assisted Joint Replacement in Revision Knee Scenarios
Marshall University published a study in ArthroplastyToday exploring the use of robotic-assisted joint replacement in revision knee scenarios using a state-of-the-art robotic arm system.
Robotic-Assisted Revision Knee Replacements
The orthopaedic team at Marshall University used a robotic assisted computer system to perform 25 revision knee replacements. The procedure involved placing new implants with the computer’s aid to ensure the knee was stable and balanced throughout the range of motion. The study carefully compared the initial positions of the primary implants with the final planned positions of the robotic revision implants for each patient, assessing the differences in millimeters and degrees.
Potential Benefits of Robotic-Assisted Surgery
The analysis of the study found that small changes in implant position significantly influence the function of the knee replacement. Robotic assistance during revision surgery has the potential to measure these slight differences, predict what size implant to use, and help balance the knee for stability. This holds promise for improved patient outcomes. The study also underscores the importance of aligning the prosthesis during revision surgery and suggests potential advantages, including appropriately sized implants that can impact the ligament tension crucial for functional knee revisions.
