Computer assisted Knee Arthroplasty - Dr. Kaushik Hazratwala

Knee replacements have been traditionally been done by bony alignment jigs. That is the surgeon uses either metal rods which are surgically inserted inside your femur or tibia and the angle of the bone cut is estimated by applying external jigs. This technique has stood the test of time for the last 30yrs.

However, the clever biomechanical engineers have in the last 15yrs developed sophisticated computer navigation techniques that allow the surgeon to accurately assess the knee alignment and movement. There is no estimation required as trackers surgically applied to the tibia and the femur track the movement of the knee in all planes. Bone resections are made according to your best fit anatomy allowing for individualised knee kinematics with minimal resection.

I perform knee replacement using Computer Navigation. I receive real time angular and alignment data before final implantation. (See attached video)

The current Australian Joint Replacement registry data (Collects data on all joint replacements done in Australia) shows that navigated knee replacements last longer in patients younger than 65. However, the more compelling data is the review articles showing that computer assisted knee arthroplasty have better alignment and is more accurately reproducible.
