Navio® Surgical System for Partial Knee Replacement

Navio HandpieceDo you suffer from knee pain? Does shooting pain, swelling, or stiffness keep you from doing the activities you love? Unfortunately, osteoarthritis of the knee affects thousands of individuals (of all ages) in the greater Phoenix area. With the Navio Surgical System – a new robotic-assisted surgical technology – relief is possible.

Improving upon traditional approaches to partial knee replacement (PKR), Navio features customized surgical plans, accurate robotic-assisted implant placement, and consistent results. Hedley Orthopaedic Institute is proud to be the first physician’s office in the Southwest and the first physician’s office in Arizona to offer Navio, the latest robotic technology for partial knee replacement. 

How does the Navio Surgical System work?

One benefit of choosing Navio is that there is no special preparation or post-operative recovery protocol. The procedure is done without a CT-scan. For patients, the CT-free approach means less time spent in the doctor’s office and lower costs.

During the procedure Dr. Chow is able to use the virtual reconstruction of your knee to create a custom surgical plan just for you. This plan allows Dr. Chow to position your implant as accurately as possible, taking into consideration factors such as your unique bone structure, cartilage wear and condylar shapes.

After creating the plan, Dr. Chow uses the Navio handpiece (pictured above) to sculpt away the bone damaged by osteoarthritis. The artificial joint is then secured into place with assistance from the Navio handpiece, which enforces bone resection to the target surgical plan.

What are the benefits of Navio?

As a partial knee replacement procedure, Navio may offer a number of benefits compared to total knee replacement, including:

  • Less pain1
  • Quicker rehabilitation and recovery2,3
  • Lower risk of complications3
