New technology helps with knee surgery

Orthopedic surgeons Dr. Nicholas Aberle II, Dr. John Vani and Dr. Timothy Monahan are now using robotics-assisted total knee arthroplasty at Providence Medical Center, using the NAVIO Surgical System.


The innovative technology involves CT-free robotics-assisted total knee arthroplasty.


A seminar about the new procedure featuring Dr. Vani will be held from 6 to 7 p.m. Jan. 29 in the Providence Doctors Building, East Tower-Suite 560. Individuals may register for the free event by calling 913-596-3940. Registration is required.


“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,” Dr. Vani said. “With the NAVIO system I’m 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.”


“Adding modern tools like robotic assistance to total knee arthroplasty adds a new level of consistency that was likely not possible before,” Dr. Aberle said. “I believe this technology will only further enhance our ability to achieve great patient outcomes.”

“Total knee arthroplasty is one of the most common procedures performed in the United States,” Dr. Monahan said. “New technology like robotic assistance aims to ensure each patient receives proper implant placement, important to great outcomes.”

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.

“The introduction of robotic assistance should have knee replacement candidates feeling very confident about the future of knee surgery,” Dr. Vani said. “I believe this technology has great promise and will eventually be used in many orthopedic surgical procedures.”

Smith and Nephew, the manufacturer of the system, is committed to developing other robotics-assisted surgical applications for the system. In the United States, the NAVIO system has been used in unicondylar knee arthroplasty since December 2012, and patellofemoral arthroplasty since July 2014.
