Frequently Asked Questions About Robotic-Assisted Knee Replacement Surgery

If you or someone you know is considering knee replacement, you may have heard about robotic-assisted options. At Glacial Ridge Health System, Dr. Joshua Thomas uses the VELYS™ Robotic-Assisted Solution for total knee replacement. Below, we answer the most common robotic knee surgery FAQ, from recovery and insurance to candidacy and what to expect.

VELYS robotic-assisted knee surgery system

Does the robot perform my knee surgery?

No. Dr. Joshua Thomas performs your entire surgery. The VELYS™ Robotic-Assisted Solution is a tool that supports his surgical planning and precision. He remains in full control throughout the procedure. Think of it as an advanced guidance system that helps your surgeon execute a plan tailored specifically to your knee.

Do I need a CT scan before robotic knee surgery?

No. The VELYS™ system is image-free, which means no pre-operative CT scan is required. Instead, your surgical plan is built in the operating room using real-time data gathered directly from your knee. This can mean less radiation exposure, fewer pre-surgery appointments, and a simpler preparation process.

What are the benefits of robotic-assisted knee replacement?

Robotic-assisted knee replacement with the VELYS™ system offers more precise bone cuts and implant positioning tailored to your specific anatomy. It provides real-time tracking and adjustment during surgery and helps ensure the muscles and ligaments around the knee are properly aligned. VELYS™ works exclusively with the ATTUNE™ Knee System, an implant used in over 1 million patients worldwide. Your surgeon will discuss what specific benefits apply to your situation.

How long does robotic knee replacement surgery take?

Robotic-assisted total knee replacement typically takes one hour, not including anesthesia preparation and post-operative recovery time. The VELYS™ system integrates efficiently into the surgical workflow, so robotic assistance does not add significant time to your procedure.

How is robotic knee surgery different from traditional knee replacement?

In traditional knee replacement, the surgeon relies on manual instruments and alignment guides. With robotic-assisted surgery, the VELYS™ system adds a layer of digital precision: capturing data about your unique knee anatomy, creating a personalized plan, and tracking the procedure in real time to help achieve more consistent implant placement. The underlying surgery and implant remain the same; robotic technology enhances the procedure’s accuracy.

How long is the recovery after robotic knee surgery?

Recovery varies by individual, but most patients begin walking with assistance on the day of surgery. Physical therapy usually starts within 24 hours. Most patients return to light daily activities within a few weeks and continue to improve over several months.

Is robotic knee surgery safe?

Yes. Robotic-assisted knee replacement carries the same general risks as traditional knee replacement surgery, including infection, stiffness, and blood clots. Complication rates for knee replacement are low overall, and the robotic technology does not introduce additional risk. The VELYS™ system is designed to enhance precision, not change the nature of the procedure. Dr. Thomas will discuss any risks specific to your health before surgery.

Will my insurance cover robotic-assisted knee replacement?

Yes, most insurance plans, including Medicare, cover robotic-assisted knee replacement because the same proven surgical procedure and implant are used. The robotic technology is an enhancement to the surgical technique, not a separate billable procedure. We recommend contacting your insurance provider to discuss your specific coverage.

Am I a candidate for robotic knee surgery?

You may be a candidate if chronic knee pain from osteoarthritis, rheumatoid arthritis, post-traumatic arthritis, or cartilage deterioration is limiting your daily activities and non-surgical treatments are no longer providing relief. The best way to find out is to schedule an appointment with Dr. Joshua Thomas at Glacial Ridge.
