Computer assisted navigation

Make an Appointment

Computer assisted surgery has been used by surgeons for many years. There are many systems in use but the most common use a camera system to record the position of markers inserted into the knee during surgery to precisely locate where the components should be placed. Computer navigation also allows for the position of saw cuts and the implants to be checked throughout surgery and adjusted as necessary.

An alternative to computer navigation is the use of computer planning from preoperative scans and the creation of customised jigs that guide Dr Negus in where to place the components. This is known as Patient Specific Implants or PSI.
