Study Shows that Robotic-Assisted Surgery Leads to Lower Revision Rates

The Journal of Bone & Joint Surgery reports that patients who received a total knee replacement have a lower revision rate, while patients who received only unicompartmental knee surgery have a higher revision rate. Total knee replacement surgeries are now being performed by orthopedic surgeons with the help of robotic-assisted techniques. According to the JBJS, surgery performed with robotic assistance, “has been proposed as a method of improving the accuracy of component implantation in arthroplasty.”
A total knee arthroplasty is a procedure where the entire knee joint is replaced with an implant, and orthopedic surgeons use robotic assistance to focus on precision to ensure that the arthritic knee is properly replaced. An unicompartmental knee arthroplasty is a similar procedure, but instead of replacing the arthritic knee joint as a whole, just one compartment of the knee is restored. The study executed by JBJS compared the results between patients who underwent a robotic-assisted surgical procedure and those who underwent a conventional surgical procedure.
During both types of arthroplasty, positioning of the knee joint and the compartments are very important. The knee is made up of four bones called the femur, tibia, fibula and patella. It is also made up of four compartments called the medial tibiofemoral, lateral tibiofemoral, patellofemoral and superior tibiofibular. The bones and compartments are in addition to ligaments and cartilage that all hold the joint together.
After three months, patients were evaluated and compared based on which type of procedure they experienced. From the JBJS study, it was found that, “the accuracy of component positioning was improved with the use of the robotic-assisted surgical procedure.” The robotic-assisted surgery resulted in fewer errors for the positioning of the joint. The surgeons who performed the procedure with robotic-assistance were closer to the target position than the surgeons who performed the operation with conventional techniques. A breakdown of the study and the results from JBJS can be found here.
Based on these results from JBJS, surgeons using robotic-assisted practices were “lead to improved accuracy of implant positioning compared with conventional unicompartmental knee arthroplasty surgical techniques.” Not only can surgery with robotic technology lead to improved accuracy and fewer revision surgeries, but this precision also leads to a faster recovery time for the patient.
It is recommended that those who may be suffering from arthritic pain in the knees or other joints schedule an appointment with an experienced orthopedic surgeon who utilizes robotic-assisted procedures.
