Total knee replacement is the name given to the operation in which the damaged bone surfaces of the knee joint are removed and replaced with an artificial knee joint. The muscles, tendons, and ligaments surrounding the knee are left in place. They provide stability to the joint. The artificial joint generally has three components. One is made of metal, usually cobalt-chrome or titanium. The other components are made from a plastic material called polyethylene, which may be strengthened by a metal plate.

The type of knee replacement selected, and whether it should be cemented or uncemented, is determined by the surgeon’s preference. This is based on many factors including the patient’s age, activity, weight, and bone quality.

Your surgeon will discuss with you what is best in your particular case.
