There are several types of arthritis but when advanced enough they all end up in severe damage to surface of the bones at the joint. That surface becomes rough and irregular. When the bones in that arthritis joint are forced to move against each other, the rubbing of the rough surfaces causes pain.In late arthritis, the main problem is roughened bone surfaces at the joint. The logical solutions available would be restoring a smooth surface to the bones. Restoring a new smooth surface is what is done is joint replacement surgery.What is arthritis?In a normal joint, bones have a smooth, glistening surface made of a substance called articular cartilage on their ends that allows one bone to glide easily against another. Joints are lubricated by a thin layer of fluid (synovial fluid) that acts like oil in an engine to keep moving parts gliding smoothly. When the articular cartilage wears out or is damaged or the joint fluid is abnormal, problems develop and joints often become stiff and painful – that’s arthritis. There are many types of arthritis, but the basic problem is the same in all types: the joint surfaces are worn out or not moving properly. In some cases, it may be possible to treat arthritic joints surgically, including “joint replacement” procedures.What does it mean to have a “joint replacement” or an “artificial joint”?The abnormal bone and lining structures of the involved joint are covered surgically, and new parts are used to cover them. These new parts may be made of special metal or plastic (certain forms of polyethylene) or specific kinds of carbon-coated implants. The new parts allow the joints to move again with little or no pain.

Knee replacement or knee arthroplasty is a surgical procedure to replace the weight-bearing surfaces of the knee joint to relieve the pain and disability of osteoarthritis. It may be performed for other knee diseases such as rheumatoid arthritis and psoriatic arthritis. In patients with severe deformity from advanced rheumatoid arthritis, trauma, or long standing osteoarthritis, the surgery may be more complicated and carry higher risk. Osteoporosis does not typically cause knee pain, deformity, or inflammation and is not a reason to perform knee replacement.Knee replacement surgery can be performed as a partial or a total knee replacement. In general, the surgery consists of replacing the diseased or damaged joint surfaces of the knee with metal and plastic components shaped to allow continued motion of the knee.A total knee replacement is a surgical procedure whereby the diseased knee joint is replaced with artificial material. The knee is a hinge joint which provides motion at the point where the thigh meets the lower leg. The thighbone (or femur) abuts the large bone of the lower leg (tibia) at the knee joint. During a total knee replacement, the end of the femur bone is covered with a metal shell. The end of the lower leg bone (tibia) is also covered with a plastic piece with a metal plate.Depending on the condition of the kneecap portion of the knee joint, a plastic “button” may also be added under the kneecap surface. The artificial components of a total knee replacement are referred to as the prosthesis.Total knee replacement (arthroplasty) has proven to be a very effective surgical treatment of osteoarthritis of the knee for many year
