Joint replacement consists of replacing painful, arthritic, worn or cancerous parts of the joint with artificial surfaces shaped in such a way as to allow joint movement.
Hip replacement (hip arthroplasty) is a surgical procedure in which the hip joint is replaced by a prosthetic implant. Such joint replacement orthopedic surgery generally is conducted to relieve arthritis pain or fix severe physical joint damage as part of the hip fracture treatment. Total hip replacement is most commonly used to treat joint failure caused by osteoarthritis. The aims of the procedure are pain relief and improvement in hip function. Hip replacement is usually considered only once other therapies, such as physical therapy and pain medications, have failed.
Knee replacement (knee arthroplasty) is a common surgical procedure most often performed to relieve the pain and disability from degenerative arthritis, most commonly osteoarthritis, but other arthritides as well. Major causes of debilitating pain include meniscus tears, osteoarthritis, cartilage defects, and ligament tears.
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.
Shoulder replacement is a surgical procedure in which all or part of the 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.
