Knee Replacement Surgery 

Carondelet St. Mary’s Hospital is proud to be the one of the first hospitals in Tucson to offer Robotic Assisted Total Knee Replacements. Using 3D computer modeling, this new technology plots complicated angles, which gives your surgeon un-paralleled accuracy to create a perfect fit between synthetic joint and natural tissue-ensuring the healthy bone and cartilage is spared. Using this technology, orthopedic surgeons can treat knee conditions with some of the most advanced technology, designed to improve patient outcomes. The Navio system provides robotic-controlled assistance to the surgeon, aiding in precise surgical outcomes for patients living with knee pain caused by early to mid-stage osteoarthritis. Navio surgery differs from other robotics-assisted surgery with unique algorithmic technology which allows for handheld instrumentation that assists the surgeon in bone resurfacing.

How Can Robotic Surgery Help

Robotic assisted surgery with the Navio system enables total and partial knee replacements that can result in a return to daily activity and decrease in pain. During the procedure, the diseased portion of the bone will be replaced with an implant that spares healthy bone and returns function.  

Partial knee replacement may offer several benefits over total knee replacement: 

  • Less pain
  • Quicker rehabilitation
  • Smaller incisions
  • Preserves ACL and PCL
  • Less bone loss

What can Navio mean for you?

  • Accurately placed implants
  • No CT radiation required
  • Customized planning from your knee 

What is osteoarthritis?

Millions of Americans suffer from the debilitating pain of osteoarthritis (OA) each day. As one of the leading causes for disability worldwide, OA is a degenerative joint disease resulting in the wearing and eventual loss of cartilage. Those suffering from OA often experience quality of life issues, loss of mobility, stiffness and swelling and joint pain activated by activity. 

How does a Navio surgery work?

A Navio knee replacement surgery works much the same way a normal knee replacement surgery works. There are no pre-operative procedures required. The difference will be in the tools the surgeon uses. 

Navio is a robotic-controlled smart instrument that delivers the precision of robotics into the surgeon’s hands, allowing for accurate and predictable bone resurfacing. 

The surgeon will re-create a model of your knee’s kinematics (movement) and bone anatomy using computer-assisted virtualization that doesn’t require input of a CT scan. Using this virtual model, the surgeon will plan the location of the implant and balance the knee through flexion (bending). Finally, using the Navio handpiece, the surgeon will prepare the bone to accept the implant.
