Robotics, Orthopaedics and Outcomes

Robotically assisted joint replacement surgery is a rapidly developing field in orthopaedics. There is good evidence that robotic techniques result in significant improvements in surgical planning, accuracy of implant position and potentially improve patient outcomes.

Background Arthritis occurs when cartilage wears away at the end of the bones causing severe pain and stiffness. Joint replacement surgery is a widely practiced technique where the damaged bone and cartilage are removed and replaced with artificial components. Knee replacement may involve the entire joint (total knee replacement) or just the damaged part of the joint (partial or unicompartmental knee replacement). Total hip replacement involves replacement of the ball and socket of the joint.

Robotic Techniques There are a number of different types of robotic surgery, some but not all of which require a computerized tomography (CT) scan prior to surgery. This additional information serves to assist in planning exactly how much bone should be removed and optimises the accuracy of positioning and alignment of the implant.

The surgeon guided robotic system is well established, allowing specific planning in patients undergoing knee replacement. This technique assists the surgeon in achieving precise resection of bone. This in turn facilitates optimum implant positioning whilst maintaining ligament balance, both of which enhance stability and mobility.

Conclusion Robotically assisted orthopaedic surgery has the potential for improving surgical outcomes. There are however significant cost implications and currently limited availability of these techniques. Mr Hoad-Reddick is delighted to be able to offer this service.

Mr Hoad-Reddick has completed a number of procedures using the NAVIO Surgical System, a handheld robotics platform designed to aid surgeons with implant alignment, ligament balancing and bone preparation. The NAVIO robotics-assisted system does not require a preoperative CT scan. This allows patients to receive the benefits of robotics-assistance without the extra steps, costs and significant radiation dose associated with additional preoperative imaging. There are other options available with more and less robotic input. For further reading, please click here:
