How Is Total Knee Replacement Surgery Performed?
Total knee replacement is performed using specific instrumentation to reproduce the joint mechanics to as near normal as possible.

The artificial joint consists of a metallic portion interspersed with a plastic component, allowing easy gliding during any joint motion.
