Total Joint Replacement

Overview

Conservative management, including medication, activity modification and physical therapy, can prevent or delay the need for joint replacement. Surgery may be an option if the patient is in severe pain, has lost cartilage, has not benefited from other treatments, and is in overall good health. The goal of join replacement surgery is to reduce pain and improve joint movement.

There are three primary joint replacement procedures: Hip, knee, and shoulder.

Hip Replacement – Total joint replacement involves surgery to replace the ends of both bones in a damaged joint to create new joint surfaces. Total hip replacement surgery replaces the upper end of the thighbone (femur) with a metal ball and resurfaces the hip socket in the pelvic bone with a metal shell and plastic liner. Hip replacement surgery replaces damaged cartilage with new joint material. Hip resurfacing is an alternative to hip replacement. A metal cap is placed on the femoral head.

Knee Replacement – The ends of the damaged thigh and lower leg (shin) bones and usually the kneecap are capped with artificial surfaces lined with metal and plastic. Usually, doctors replace the entire surface at the ends of the thigh and lower leg bones. But it is increasingly popular to replace just the inner knee surfaces or the outer knee surfaces, depending on the location of damage. This is called partial replacement, or unicompartmental replacement. Doctors usually secure knee joint components to the bones with cement.

Shoulder Replacement – Doctors replace the ends of the damaged upper arm bone (humerus) and usually the shoulder bone (scapula) or cap them with artificial surfaces lined with plastic or metal and plastic. As with knee and hip replacement, shoulder joint components may be held in place with cement. Or they may be made with material that allows new bone to grow into the joint component over time to hold it in place without cement. The top end of the upper arm bone is shaped like a ball. Muscles and ligaments hold this ball against a cup-shaped part of the shoulder bone. Surgeons usually replace the top of the upper arm bone with a long metal piece, inserted into your upper arm bone, which has a rounded head. If the cup-shaped surface of your shoulder bone that cradles your upper arm bone is also damaged, doctors smooth it and then cap it with a plastic or metal and plastic piece.

In Depth Data:

Knee Replacement

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.[1] 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.

Hip Replacement

Hip replacement is a surgical procedure in which the hip joint is replaced by a prosthetic implant. Hip replacement surgery can be performed as a total replacement or a hemi (half) replacement. Such joint replacement orthopaedic surgery generally is conducted to relieve arthritis pain or fix severe physical joint damage as part of hip fracture treatment. A total hip replacement (total hip arthroplasty) consists of replacing both the acetabulum and the femoral head while hemiarthroplasty generally only replaces the femoral head. Hip replacement is currently the most common orthopaedic operation, though patient satisfaction short and long term varies widely.

Shoulder Replacement

Shoulder replacement is a surgical procedure in which all or part of the glenohumeral joint is replaced by a prosthetic implant. Such joint replacement surgery generally is conducted to relieve arthritis pain or fix severe physical joint damage.Shoulder replacement surgery is an option for treatment of severe arthritis of the shoulder joint. Arthritis is a condition that affects the cartilage of the joints. As the cartilage lining wears away, the protective lining between the bones is lost. When this happens, painful bone-on-bone arthritis develops. Severe shoulder arthritis is quite painful, and can cause restriction of motion. While this may be tolerated with some medications and lifestyle adjustments, there may come a time when surgical treatment is necessary.

Elbow Replacement

Elbow replacement surgery is usually done if the elbow joint is badly damaged and you have pain or cannot use your arm. Some causes of damage are: Osteoarthritis, Poor outcome from previous elbow surgery, Rheumatoid arthritis, Badly broken bone in the upper or lower arm near the elbow, Badly damaged or torn tissues in the elbow, Tumor in or around the elbow.
