Robot Assisted Surgery

Surgical precision and improved measurements

No, it’s not science fiction! Robot-assisted joint replacement (RJR) is a new advance in the field of total knee arthroplasty. The use of robots improves the precision of joint replacement operations. You are unique, as is your anatomy. That’s why Zimmer Biomet offers ROSA® Knee robotic technology. ROSA, which stands for Robotic Surgical Assistant, is designed to help your surgeon perform customized surgery.

If you are a candidate for total knee replacement surgery, robotic-assisted surgery may be right for you. Our surgeons currently use robotic technology for knee replacement surgery. Ask your doctor if you are a good candidate for robotic-assisted surgery.

Please listen to Dr. Massé explaining the personalized knee replacement principles and demonstrating the ROSA robot precision here.  

How does robot-assisted surgery work?

It is important to know that the robot does not perform the operation. Your surgeon remains in control. The robotic system helps your surgeon perform the operation more precisely.

Robots assist in preoperative planning. Each individual has a unique anatomy. With this advanced technology, our surgeons plan your surgery before they meet you in the OR. This ensures that the implant size and placement are carefully selected to fit your unique anatomy.

The robotic arm also precisely positions the saw blade during a total knee replacement operation so that the surgeon only works within predefined dimensions.

Which is better, robotic surgery or navigation?

Both are precision tools. In both cases, surgeons use computer assistance in total knee arthroplasty to achieve optimal implant alignment, sizing and positioning through real-time surgical navigation. An added benefit of robotic assistance is that it helps the surgeon make the proposed bone cuts by firmly and accurately positioning the cutting blocks during surgery, while providing real-time verification of cut accuracy.

During the surgery

During your procedure, ROSA Knee uses a camera and optical trackers attached to your leg to know exactly where your knee is in space. Think of it as a very detailed global positioning system (GPS) that you might use in your car. If your leg moves even a fraction of an inch, the robot knows and adjusts accordingly. This ensures that the plan set up by your surgeon is carried out as planned. Throughout your operation, ROSA knee provides your surgeon with data about your knee. This information, combined with your surgeon’s expertise, helps him or her know how to position your implant based on your unique anatomy. Check out this link to see the robot in action.

Is there an additional cost?

Robotic technology is a high-tech tool that has required years of development. Clinique Duval has acquired such a robot to benefit its clientele. However, the use of this precision tool involves an additional cost. If you are interested, we will be pleased to give you more information.
