NAVIO Robotics-Assisted Knee Replacement Surgery

More accurate with better results

People suffering from joint pain in their knees are benefiting from a new robotics-assisted, knee replacement surgery that provides greater accuracy during surgery, less pain and improved recovery.

West Tennessee Bone & Joint Clinic, P.C. physicians in Jackson are using the NAVIO Surgical System at the Physicians Surgery Center and Jackson-Madison County General Hospital.

With any total knee arthroplasty surgery, final placement of the implant is critical to providing both the function and longevity that today’s patients expect. With the NAVIO system, surgeons are able to see real-time data throughout the surgery that is designed to help place each implant in the optimal location based on each patient’s unique anatomy.
Unlike other robotics-assisted platforms, the NAVIO system does not require a pre-operative CT-scan. Instead, the surgeon collects patient-specific data during the procedure to build a 3D model of the patient’s knee. This is used to plan the surgery. To perform the procedure, a handheld robotics-assisted tool (the NAVIO handpiece) is used to position NAVIO-specific cut guides exactly as intended, based on the patient-specific data previously collected. This extra layer of precision and accuracy is designed to enable optimal implant placement for better patient outcomes.

West Tennessee Bone and Joint Clinic physicians in Jackson began using the NAVIO robotics-assisted surgery for both total and partial knee replacement in July 2018. When they did so, the Physicians Surgery Center became the first free-standing, physician-owned ambulatory surgery center in Tennessee to offer robotic-assisted orthopedic surgery.

Many patients can get relief from knee pain with partial knee replacement surgery. They don’t have to wait in pain until they are a candidate for full knee replacement.

Common questions and answers

Who would be a good candidate for a total knee procedure using the NAVIO system?

Although the best treatment for each patient must be determined individually, typical patients share the following characteristics: 

    1. Severe knee pain or stiffness that limits your everyday activities
    2. Moderate or severe knee pain while resting
    3. Chronic knee inflammation and swelling that does not improve with rest or medications
    4. Failure to substantially improve with other treatments such as anti-inflammatory medications, cortisone injections, lubricating injections, physical therapy, or other surgeries

Who would be a good candidate for a partial knee procedure using the NAVIO system? 

Although the best treatment for each patient must be determined individually, typical patients share the following characteristics: 

    1. A person with chronic knee pain isolated to a single area of the knee such as the inner knee
    2. A person with knee pain or stiffness when activities are initiated from a sitting position
    3. A person who has failed to respond to non-surgical treatment such as rest, weight loss, physical therapy and non-steroidal anti-inflammatory medication  

How long can I expect the implant used in a using the NAVIO procedure to last? 

  1. Many factors can impact an implant’s longevity and function. The NAVIO Surgical System is designed to address the issues of implant alignment and positioning.
  2. Implants that are misaligned or positioned incorrectly may be subject to early failure or may function less effectively.
  3. The goal of a NAVIO procedure is to achieve the best alignment and positioning possible for your implant to help it last as long as possible.

What are the benefits of the NAVIO surgical system? 

  1. Robotic assisted technology is designed to help a surgeon with accurate and individualized implant planning and positioning.
  2. Unlike other robotic systems, NAVIO is CT-free technology
  3. Because the NAVIO system can work with a variety of implants for both partial and total knee replacement, a surgeon is able to select the appropriate implant for each patient.
