Both total knee arthroplasty and unicompartmental knee arthroplasty procedures can be performed either with or without computer assisted surgery (CAS).

CAS makes use of computer technology for surgical planning, as well as for the performance of surgery. The technology is used as a form of medical imaging, in which x-rays, CT scans, ultrasound and MRI can all be used to generate a model of the patient’s body. This allows Dr Marais to properly plan a surgical procedure in accurate detail because he is able to see exactly where fragments of bone and cartilage are located.


We provide an orthopaedic service dedicated exclusively to the problems of the knee. This covers the whole spectrum of knee problems ranging from paediatric to geriatric knee problems. Our practice will take a personal approach to your problem if you have specific needs in mind.
