What is Knee Replacement?

In total knee replacement surgery, the parts of the bones that rub together are resurfaced with metal and plastic implants. Using special, precision instruments, Surgeon will typically remove the damaged surfaces of all three bones. The replacement surfaces will then be fixed into place.

How Knee Replacement is Done ?

Once you are under general anaesthesia or spinal/epidural anaesthesia, an 6 inch cut is made in the front of the knee. The damaged part of the joint is removed from the surface of the bones, and the surfaces are then shaped to hold a metal or plastic artificial joint called Prosthesis. The Prosthesis is attached to the thigh bone, shin and knee cap with cement. When fit together, the attached artificial parts form the joint, relying on the surrounding muscles and ligaments for support and function.

All preparations for surgery should be discussed with your surgeon.
