The robotic system works in conjunction with the surgeon's hands to achieve the precise positioning of the knee implant.

Using the Navio robotic-assisted hand piece enables your Navio-certified, board certified and fellowship trained surgeon to plan the surgery accurately intraoperatively, position the implants, and reduce the risk of errors during the procedure, while decreasing the length of time it takes for you to recover and return to your formerly active lifestyle enjoying friends, family, recreation, shopping, and other active leisure activities.

ARE YOU A CANDIDATE FOR Knee Replacement with NAVIO Robotic-assisted Surgical System?

Is Living With Knee Pain Really Living?

If you’re one of the millions of people suffering from osteoarthritis, discover how knee replacement using NAVIO robotic assistance may help you return to the activities you love.

Find out today how St George Surgical Center can help you return to an active lifestyle.

St George Surgical Center, a physician-owned, accredited outpatient surgery center has invested in cutting edge technology to improve overall patient health: the NAVIO robotics-assisted surgery is an advancement in orthopedics putting accuracy in your surgeon’s hands that could result in a longer lasting knee. Contact our care coordinator today at (435) 705-7039 or toll free at (844) 673-0095, and we’ll answer your questions refer you to our two board-certified, fellowship trained, NAVIO– qualified orthopedic surgeons for an initial consultation and review of your medical records and imaging studies. If you live outside St George, it will be our pleasure to coordinate all your travel and accommodation.

What robotic-assisted full/partial knee replacement patients are saying:

“When I compare my NAVIO knee replacement surgery to my previous conventional surgery two years ago, I see a huge difference. I could not walk or even bend my knee one month and a half after the previous surgery. This time, I was able to walk two days after. I am using a cane for added support now, but I can also walk without it — and today I drive myself wherever I like. I have my independence back!"

How Do I Know If I am a Candidate for Robotic-Assisted Knee Replacement Using the NAVIO System?

Although each patient must consult with a physician individually, typical knee replacement candidates share the following characteristics:

  • Knee pain in the knee during activities
  • Knee pain is limiting activities on more days than not
  • Initial knee pain or stiffness caused by activities from a seated position
  • No longer finding relief from non-surgical treatment options​

Not everyone is a candidate for knee replacement using the NAVIO Surgical System. Knee replacement surgery is intended to relieve knee pain and improve hip function. However, implants may not produce the same feel or function as your original knee. There are potential risks with knee replacement surgery such as loosening, fracture, dislocation, wear and infection that may result in the need for additional surgery. Individual results will vary. Talk to your doctor to determine what treatment may be best for you.



Total and partial knee replacement surgery with the NAVIO Robotic-assisted Surgical System is a technically demanding surgery. Surgeons face a steep learning curve for this procedure, so choosing a surgeon that is skilled and certified to use the NAVIO Robotic-assisted Surgical System is an important consideration.  In St George Utah, there are currently only two NAVIO qualified surgeons … and they only operate at St George Surgical Center in Southern Utah where the robot is available.

The NAVIOsystem works in conjunction with the surgeon’s hands to achieve the precise positioning of the knee implant based on each patient’s unique anatomy.

This added level of accuracy can help improve the function, feel, and potential longevity of the partial knee implant.

NAVIO also provides robotic assistance through an advanced computer program that relays precise information about the patient’s knee to a robotics-assisted hand piece used by the surgeon during the procedure.

By collecting patient-specific information, boundaries are established for the hand piece so the surgeon can remove the damaged surfaces of the knee, balance the joint, and position the implant with greater precision.

The robotics and AI enhance control of the surgical variables to improve outcomes including proper size, implant positioning, soft-tissue balance, and lower limb alignment,.

Recent studies showed that one per cent revision of the procedure is needed two years after the surgery — which is four times lower than that of the conventional technique of knee replacement.

The future of health and science has already revolutionized the way orthopedic surgeons work. Technology like this will help lead research and education in the science of knee replacement surgery to the benefit of patients, worldwide.

Accurate Implant Placement

Our physicians use the NAVIO system to perform robotics-assisted partial knee replacement. They chose this technology because it allows them to individualize each patient’s knee replacement surgery, and use robotic assistance for accurate results.1

With the NAVIO system, there is no special pre-operative preparation or post-operative recovery protocol. The NAVIO system does not perform the procedure; rather it assists the surgeon by providing accuracy — crucial to the success of the surgery.
