Navio Partial Knee Replacement

NAVIO® Robotics-Assisted Surgery

Accurate and Precise Implant Placement

Our physicians use the NAVIO Surgical System to perform robotics-assisted partial knee replacement, and more recently robotics-assisted total knee replacement as part of a limited market release program. Our physicians chose this technology because it allows them to individualize each patient’s knee replacement surgery and use robotic assistance for accurate and precise results.

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 and precision — crucial to the success of the surgery.

NAVIO Robotics-Assisted Partial Knee Replacement

The Process Starts by Planning the Procedure with Your Unique Knee Anatomy in Mind

Rather than a radiation-intensive CT-scan, the NAVIO system uses a bone surface mapping technique to collect information about your knee. The information collected is used to generate a 3D model, which your surgeon will use to virtually position the metal and plastic implant components that will replace your damaged knee. This is done prior to bone resurfacing so the surgeon can be sure the plan is right for you.

Once your surgery plan is finalized, your surgeon will use a robotics-assisted surgical tool (the NAVIO handpiece) to accurately remove the damaged surface of your knee. To complete the procedure, the implant components are positioned and the surgeon receives computer confirmation that your surgery was performed according to the plan.


Partial Knee Replacement with Traditional Techniques

Using traditional surgical methods, bone cutting guides are placed on the thigh bone (femur) and shin bone (tibia) to help direct a surgical saw in removing the diseased bone and cartilage. This method has been considered technically challenging, as accurately placing these guides can be difficult. Recently, advanced surgical techniques using robotic assistance like the NAVIO system have been developed to provide a higher level of precision and consistency.

Why chose partial knee replacement?
For patients who are candidates, partial knee replacement compared to total knee replacement offers:

  • Less pain
  • Quicker rehabilitation and recovery
  • Lower risk of complications
  • Smaller incisions
  • A more normal feeling knee

Why chose NAVIO robotic assistance?

  • Consistent results
  • Accurately placed implants
  • Customized implant planning
  • CT-free technology
    • 1 CT-scan is equivalent to radiation exposure seen in 48 chest radiographs   

Hear from patients who’ve had a NAVIO robotics-assisted procedure

Lee, 61, is an avid outdoorsman who has been actively involved in horseback riding and rodeos his entire life. After years of struggling with worsening knee pain, he eventually became physically unable to enjoy the outdoors and participate in the activities he loved. Ready for change, Lee elected for a NAVIO robotics-assisted partial knee replacement.

Karla, 71, enjoys an active retired lifestyle spending her winter months in Texas. In recent years knee pain has made it increasingly difficult for her to make the trip south, and too painful to participate in exercise groups with the rest of her community. Eventually diagnosed with osteoarthritis, but not severe enough to require a total knee replacement, Karla elected for a NAVIO robotics-assisted partial knee replacement.

Evan, 54, has been a competitive athlete her whole life. She competed in tennis, rowed in college and cycled professionally. At 17 years old Evan tore her lateral meniscus. She has suffered from chronic knee pain since and had been forced by the pain to reduce the number of actives she pursued. Since undergoing NAVIO robotics-assisted partial knee replacement surgery, Evan is pain free and able to live the active lifestyle she enjoys.

Lucio, 76, is a soft spoken and hardworking man who has spent his entire life providing for his wife, 4 kids, and growing family of 11 grandchildren. Struggling with knee pain and unable to keep up with his daily activities, Lucio was not sure where to turn as he witnessed his wife, Maria, struggle to recover from a total knee replacement procedure. Lucio eventually elected for a NAVIO robotics-assisted partial knee replacement.

Please Note:

As with any surgical procedure there are risks involved with partial knee replacement which may include, but are not limited to:Blood clots. Your physician may prescribe medication to help prevent blood clots Infection. Antibiotics may be given before the surgery and continued afterward to help prevent infection Injury to nerves or vessels. While rare, nerve and blood vessel damage may occur during the procedure Other risks. Individual patient risks should be discussed with your surgeon Consult with your physician for details to determine if a NAVIO robotics assisted procedure is right for you The NAVIO system is not for everyone. Children, pregnant women, patients who have mental or neuromuscular disorders that do not allow control of the knee joint and morbidly obese patients should not undergo a NAVIO procedure. Knee replacement surgery is intended to relieve knee pain and improve knee functions. 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. Longevity of implants depends on many factors, such as types of activities and weight. This information is provided for informational and educational purposes only, and is not intended to be nor should it be construed as medical advice. Consult your physician for details to determine if a NAVIO robotics assisted procedure is right for you. The NAVIO system is intended to assist the surgeon in providing software-defined spatial boundaries for orientation and reference information to anatomical structures during orthopedic procedures. The NAVIO system is indicated for use in surgical knee procedures, in which the use of stereotactic surgery may be appropriate, and where reference to rigid anatomical bony structures can be determined. These procedures include unicondylar knee replacement (UKR), patellofemoral arthroplasty (PFA), and total knee arthroplasty (TKA). The NAVIO system is indicated for use with cemented implants only.
