Knee Replacement with the VELYS™ Robotic-Assisted Solution
A knee replacement is a procedure performed to fix the damaged parts of a knee with different types of implants. Every knee is different, as is every patient requiring a knee replacement procedure. Advanced technology like robotic-assisted devices can help your surgeon perform a precise knee replacement surgery personalized for your specific anatomy.1,2 The VELYS™ Robotic-Assisted Solution is designed for digital precision, which may improve early patient outcomes following total knee replacement surgery.2
How does the VELYS Robotic-Assisted Solution work
The VELYS Robotic-Assisted Solution uses a variety of advanced technologies to provide the surgeon with the information and tools they need to perform an accurate and precise knee replacement.1,2
This solution is designed to:
- Aid your surgeon by accessing state-of-the-art technology to provide insights for real-time decision making.1,2
- Help your surgeon remove the damaged bone with accuracy.1,2 This robotic-assisted device does not move or operate on its own. Your surgeon remains in control of the surgery and uses the system for guidance.
- Gather the necessary data about your knee’s unique anatomy through the use of an infrared camera and optical trackers

Which implant will be used with the VELYS Robotic-Assisted Solution?
For total knee replacement, the VELYS Robotic-Assisted Solution works exclusively with the ATTUNE™ Knee System. The ATTUNE Knee System has been provided to over 2 million patients worldwide4 and is designed to deliver a greater range of motion and faster recovery, so you can get back to living the life you want to live.5,6 For patients who may be a candidate for partial knee replacement, the VELYS Robotic-Assisted Solution works exclusively with the SIGMA™ HP Partial Knee System, which has been received by nearly 130,000 patients since it became clinically available in 2008.7
How does robotic-assisted knee replacement compare to a traditional knee replacement?
The goals of robotic-assisted knee replacement and traditional or manual knee replacement are the same:
- Restore the knee joint by removing the damaged bone and cartilage
- Replace the damaged surfaces with a knee implant
The primary difference between the two approaches to knee replacement are the enabling technologies that aid the procedure.
What are the benefits of using robotic-assisted technology?
There are several potential benefits to using this technology for your knee replacement. During your procedure, the technology will gather details and data related to your knee to help find a favorable implant fit. Additionally, robotic-assisted technology may allow your surgeon to perform a knee replacement tailored to you, while providing both precision and accuracy during your procedure.1,2
Robotic-assisted technology may deliver*:
- A greater range of motion (how well you can bend and flex your knee after surgery)8,9
- Less pain compared to traditional methods2,8
- Faster recovery times (reduced length of hospital stay, hospital re-admissions, and health visits)2,10

Important Safety Information
As with any medical treatment, individual results may vary. The performance of knee replacements depends on age, weight, activity level and other factors. There are potential risks, and recovery takes time. People with conditions limiting rehabilitation should not undergo this surgery. Only an orthopaedic surgeon can determine if knee replacement surgery is an option for you.
