KNOXVILLE, Iowa – Knoxville Hospital & Clinics (KHC) is excited to announce that Dr. Todd Peterson has performed the first NAVIO robotic-assisted total knee replacement surgery in Iowa. Dr. Peterson was also the first surgeon in central Iowa to perform NAVIO robotics-assisted partial knee replacement surgeries, beginning in late 2016.

“The NAVIO robotics system has changed the way in which knee replacement surgeries are performed,” said Dr. Peterson. “It allows surgeons to customize each patient’s surgical plan intra-operatively, so there is a clear plan for positioning the joint implant. There is no pre-operative CT scan required, so the cost of the entire procedure is less, and the patient is not subjected to radiation. During surgery, the robotics technology allows the surgeon to make any necessary adjustments, providing for a higher level of accuracy and predictability. The combination of these features of the system has the potential to lead to better outcomes and higher patient satisfaction.”

Robotic-assisted surgery is a new approach to joint replacement that offers a higher level of patient-specific implant alignment and positioning. The technology allows surgeons to create a patient-specific 3D plan and perform joint replacement surgery using a surgeon-controlled robot that helps the surgeon execute the procedure with a higher degree of accuracy.

The total knee NAVIO system is now an option for patients who are suffering from advanced arthritis of the knee that are not candidates for partial knee replacement.  During surgery, the surgeon guides the robot during bone preparation to prepare the knee joint and position the implant according to the pre-determined surgical plan.

“We are proud to be the first hospital to use this innovative technology in Iowa,” said Kevin Kincaid, Chief Executive Officer at KHC. “It is part of our commitment to be Iowa’s healthcare destination for partial and total knee replacement surgeries.”
