In total knee replacement, an incision is made in the front of the knee to allow exposure inside the joint. Once inside the joint, the cartilage that has been destroyed from the process of arthritis is removed almost like a capping on your tooth. The end of the bone is shaped to accept the components on both the femur and the Tibia.
Using either robotic or manual surgical techniques, the knee is then balanced both in extension as well as flection, requiring a nice stable balanced knee replacement.
The final components are then cemented into place with a type of surgical cement, which acts more like a grout going into the intricacies of the bone and hardening in place. Then a plastic component called polyethylene is inserted in between the two metal components and the knee replacement is complete.
