Robotics-Assisted Partial Knee Replacement

If you’ve considered knee surgery but have been putting it off, you’ll want to read this.

Studies show that close to 50% of people will develop osteoarthritis, a degenerative bone disease that can cause knee cartilage to break down. Delaying treatment can cause more damage and more pain — and it can eventually reduce your surgical options.

A new, robotics-assisted partial knee replacement surgical option is a game-changer in knee surgery. And our own Dr. Todd Peterson is the only surgeon in central Iowa who’s certified to perform this advanced procedure.

NAVIO(R) robotics-assisted partial knee surgery


NAVIO robotics-assisted partial knee surgery is a big advancement in partial knee replacement. The patented system works with the surgeon’s skilled hands to achieve precise positioning of the knee implant for each patient’s unique needs.

How it works

Traditional surgical methods use cutting blocks or guides to direct a surgical saw. That can be technically challenging and lead to an increased risk of surgical error and complications.

The NAVIO system adds a new level of accuracy. During the procedure, it sends precise information about your knee to a robotics-assisted handpiece used by Dr. Peterson. This patient-specific data sets boundaries for the handpiece — so he can remove the damaged surfaces of your knee, balance your joint and position the implant with increased precision. This leads to better, longer lasting a results.

What increased precision can do for patients

Increased precision during partial knee replacement surgery typically translates into big benefits for patients. These can include:

  • Faster recovery
  • Fewer complications
  • Longer lasting results
  • Less pain
  • Better mobility

  • Is NAVIO robotic-assisted partial knee surgery for you?


    Patients who experience knee pain or stiffness — and who don’t respond to non-surgical treatments such as activity modification, weight loss, physical therapy or non-steroidal anti-inflammatory medication — may be good candidates for NAVIO robotics-assisted partial knee surgery.

    Surgery performed at Knoxville Hospital & Clinics

    You can see Dr. Peterson for an evaluation at our Clive office, as well as at Knoxville Hospital & Clinics and at Dallas County Hospital. He performs the NAVIO procedure itself at Knoxville Hospital & Clinics, which is the first and only medical facility in central/southern Iowa to offer the NAVIO system.
