Total Joint Replacement

What is total joint replacement?

When an arthritic or damaged joint is removed and replaced with an artificial joint called a prosthesis.

How is a total joint replacement performed?

You will be given an anesthetic and the surgeon will replace the damaged parts of the joint. For example, in an arthritic knee the damaged ends of the joints are replaced with metallic & non allergic & durable plastic surfaces that are shaped to restore knee movement and function. In an arthritic hip, the damaged ball is replaced by a metal ball attached to a metal stem fitted into the femur, and a plastic socket is implanted into the pelvis, replacing the damaged socket. Although hip and knee replacements are the most common, joint replacement can be performed on other joints, including the ankle, foot, shoulder, elbow, and fingers.

The materials used in a total joint replacement are designed to enable the joint to move just like your normal joint. The prosthesis is generally composed of two parts. A metal piece that fits closely into a matching sturdy plastic piece. Several metals are used, including stainless steel, alloys of cobalt and chrome, and titanium. The plastic material is durable and wear resistant. A plastic bone cement may be used to anchor the prosthesis into the bone. Joint replacements also can be implanted without cement when the prosthesis and the bone are designed to fit and lock together directly.


Total knee replacement is an increasingly effective and desirable approach to a range of problems affecting the knee. It is one of the most consistently successful therapeutic measures in all of medicine and surgery today. Overall patient satisfaction with the relief of pain and enhanced mobility is, in general, extremely high. The procedure can provide many years of improved mobility and reduced pain.

Though a total knee replacement is a major operation, you should not feel alone in taking this path : each year almost half a million all over the world benefit from it. This information is aimed to make you understand how a total knee replacement can improve the quality of your life, we suggest that you speak to someone who has had the successful surgery.

A Closer Look at Total Knee Replacement

To understand a total knee replacement, it helps to understand the structure of the knee joint. The knee is a complex joint that involves three bones: the femur, the tibia, and the patella. When you bend or straighten your knee, the end of the femur rolls against the end of the tibia, and the patella glides in front of the femur.

Research has steadily improved the materials available for knee replacement. The durability of the prosthesis can very from patient to patient because each patientís body places slightly different stresses on a new knee. Even so, you can expect to enjoy improved mobility, relief of pain and the ability to walk for many years to come.


In a total hip replacement surgery, the painful parts of the damaged hip are replaced with artificial hip parts called prosthesis, a device that substitutes or supplements a joint. The prosthesis consists of three components: a socket, ball, and stem. The outer shell of the socket is usually made of metal and the inner shell consists of plastic or the entire socket may be plastic. When the metal ball is joined with the socket, the new hip allows for smooth nearly frictionless movement.
