The NAVIO Surgical System at Circle Reading Hospital

Get your knee replaced with the latest robotics-assisted technology

As a private patient, you can choose to have a knee replacement using state-of-the-art robotics-assisted technology. Now available at Circle Reading Hospital, the NAVIOTM Surgical system helps some of the country’s leading surgeons to deliver even greater accuracy during your operation, while also eliminating the need for a CT scan before surgery.

What is the NAVIO system?

Designed by Smith & Nephew, a world leader in joint replacement systems, the NAVIO system provides robotic assistance to our surgeons through an advanced computer programme.

The system works in conjunction with our surgeons’ skilled hands to achieve the precise positioning of the knee implant based on your unique knee anatomy, providing extra layers of planning, accuracy and precision.

It works by relaying precise information about your individual knee to the surgeon through a specially designed handpiece. This data helps the surgeon to remove the damaged surfaces of your knee, balance your joint, and position the implant with greater precision.

The benefits of NAVIO

The NAVIO system offers you two key benefits.

First, it helps your surgeon create a highly individualised plan that is specific to the unique shape and motion of your knee. Traditionally, a CT scan may be needed to show cross-sections of your knee. The NAVIO system works without this, instead creating a 3D representation of the unique shapes and profiles of your knee. This also helps to speed up the consultation process.

Secondly, the NAVIO system is specifically designed to help your surgeon during the operation. The latest technology helps to provide even greater accuracy for total or partial knee replacements1.

Mr Tony Andrade, Consultant Orthopaedic Surgeon, said: “The NAVIO system provides a win-win solution for both patients and orthopaedic surgeons performing partial and total knee replacements. It provides robotic assistance to help surgeons perform knee replacements with even greater accuracy and precision than before. Looking to the future, I have little doubt that in ten years’ time all knee replacements will be carried out with some form of robotic assistance. The NAVIO system is a fantastic starting point for us on that journey."


What can I expect in a consultation?

During an initial consultation, your surgeon will get a full background of your knee injury and complete a thorough examination. You may also be referred for diagnostic scans in order to reach a diagnosis and suggested treatment plan.

If your surgeon recommends a total or partial knee replacement, and they believe the NAVIO system would be of benefit, they will talk you through the options. This will include information about how it works, alongside both the benefits and risks to surgery.

If you’re a private patient at Circle Reading Hospital, then you can choose to have the operation with or without the NAVIO technology. If you’re paying for yourself, we’ll provide an all-inclusive quote for each option. If you’re using private medical insurance, we’ll provide everything you’ll need in order to seek pre-authorisation from your insurer.

To help you decide, we’ll also give you a patient information leaflet to take away. If you have any further questions, your consultant will be happy to help.

How can NAVIO help with a total knee replacement?

The NAVIO system is designed to help your surgeon not only plan your surgery based on your unique knee anatomy, but also position your total knee implant using a combination of computer and robotic assistance.

The NAVIO procedure starts with an advanced computer system that gathers precise anatomic and alignment information about your joint that your surgeon will use to create your specific surgical plan.

This extra layer of data collection and planning is designed to help ensure your knee procedure is performed exactly as your surgeon intends and that your implant is positioned as accurately as possible for the best long-term outcome.

NAVIO partial knee replacement surgery

A partial knee replacement must achieve an exact balance between the new implant - made of metal and plastic components - and the remaining portions of your natural anatomy made of bone and cartilage.

The NAVIO system helps your surgeon using both computer and robotic assistance to accurately map the surface of your knee, align your implant to your anatomy, and physically remove the bone necessary to place your new implant. This added level of assistance is important because implant alignment is a crucial factor in determining how long the implant will last2.
