Computer Aided Knee Surgery

Computer Aided Knee Surgery is a recent advancement in knee treatment. This improves the accuracy levels of the surgical process. The introduction of computer assisted navigation techniques improve precision of joint replacements.

Failure of knee replacement surgery is a small percentage. These shortfalls can be attributed to:
1) Difficulty in pinpointing anatomical landmarks
2) Appreciating minor variations of angles with naked eye
3) Inability to judge equal soft tissue tension

Computer assisted Knee Surgery is state-of-the-art practice for optimizing success rate of knee treatment and replacement.

The navigation unit of a Computer-aided-surgery unit is a sophisticated surgical tool which consists of: 1. camera 2. touch-screen 3. computer base unit and 4. sensors placed on patient

The computer creates a 3-dimensional model of the patient’s knee as follows and guides the surgeon on a dynamic basis to correct the deformity, to ensure equal soft tissue tension and for precise placement of the artificial joint

Comparing the computer images with pre-operation X-Ray images of the deformity:

The post-operation X-ray images of the knee are as follows:

High Flexion Knee

High flexion in total knee replacement is any flexion beyond 125 degrees. Many Asian patients refuse knee replacement as they cannot squat post-operation. With high flexion implants which have a rotating platform, patients are able to kneel and pray.
