NAVIO – the cutting-edge of surgical robotics for knee arthroplasty

Waratah Private Hospital cements it’s commitment to surgical excellence as a leader in medical technology with Smith & Nephew’s NAVIO Surgical System, the first of its kind in New South Wales.

The NAVIO is an innovative hand-held robotic surgical device which, teamed with a surgeon’s skilled hand, enables pinpoint accuracy during total knee arthroplasty (TKA) and unicompartmental knee arthroplasty (UKA).

How does this change knee arthroplasty?

The NAVIO’s impressive capabilities include the ability to map the patient’s knee in real-time as a 3D model, allowing virtual placement of the implant to predict postoperative joint laxity.

During surgery, the advanced computer program relays precise patient-centric information to the hand-piece. Removing the damaged bone and cartilage of the knee can be done while assessing the patient’s anatomy on a real-time screen.

The improved joint’s laxity can also be assessed before the surgery is complete by moving the leg through flexion/extension, confirming successful alignment and placement.

The NAVIO vs current methods of surgery

The NAVIO mitigates the challenges of traditional methods of knee surgery, and simplifies the surgical process without the extra steps required with existing robotic-assisted technology, such as CT scans, cutting blocks and guides. As a portable device, it eliminates bulky, fixed electronic arms.

The NAVIO is considered a sterile device that avoids the risk of infection to patients. It uses an implant with a seven-year track record of successful clinical outcomes recorded by the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR). Some robotic systems currently in use require new specifically designed implants, which can increase risk of complications for patients.

What does the NAVIO mean for your patient?

A patient may benefit from shorter surgery times, less pain, a more rapid recovery and improved knee mechanics post-surgery.
