Computer assisted navigation - high tibial osteotomy

What is computer assisted navigation?

Computer assisted navigation is where computer technology is used to guide surgeons during joint replacement surgeries. It's performed through the use of a computer navigation machine, which enables the surgeon to digitally monitor each step of the surgery on a screen. 

How does this procedure work?

The position of individual bones is tracked in 3D space with real time infra-red wave communication. The surgeon is able to make exact individualised cuts in bones and position the prosthesis in the desired position to the last degree. Any adjustment needed is done during the surgery as opposed to conventional surgery when the objective measurements are on post op evaluation.

What is most beneficial is the cuts are individualised catering to specific anatomy and needs of each individual patient. The surgeon can measure exactly how much difference they are making to the leg alignment angles which is of paramount importance in high tibial osteotomy as the operation is based on realignment of the leg.

Meeting with your consultant surgeon will ensure that you have the opportunity to ask any questions you may have about your high tibial osteotomy.

How soon will I recover?

It takes about six months for the knee to fully recover.

You might stay in the hospital for about two days, under the direct supervision of you consultant and care team. A knee brace or cast might be fitted so that the knee is protected. After 10-14 days your stitches will be removed.

In order to reduce the weight put on the knee you will need to use crutches or sticks for the following weeks. Regular exercise with a physiotherapist should help you return to normal activities as soon as possible.
