What is Knee replacement surgery?
In knee replacement surgery, the damaged parts of the bones making up the knee, which rub together, are removed using highly specialized instruments and replaced with metal and plastic implants.
In total knee replacement surgery, the parts of the bones that rub together are resurfaced with metal and plastic implants. Using special, precision instruments, your surgeon will typically remove the damaged surfaces of all three bones. The replacement surfaces will then be fixed into place.
How is Knee Replacement done ?
Once you are under general anaesthesia or spinal/epidural anaesthesia, a 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.
