What is total joint replacement surgery?
The goal of total joint replacement surgery is to relieve pain and to restore function and mobility by repairing a damaged joint. During the procedure, parts of the joint are removed and replaced with a metal, plastic or ceramic device.
What causes joint pain?
Problems with major joints like the hip and knee are most frequently the result of arthritis.
- Osteoarthritis is the most common form of arthritis. It is most often related to the wear and tear of the cartilage over the years. Its onset is usually after age 50. As the cartilage is worn away, exposed bones rub together causing pain, inflammation, immobility and further damage to the joint. Factors that may predispose people to this condition include family history, obesity and previous joint surgery or fractures.
- Rheumatoid Arthritis (RA) is one of the more common kinds of inflammatory arthritis. It is a long-term disorder that affects the joints of the body. RA is likely an autoimmune disease, which means body cells irritate the lining around the joint leading to destruction of the cartilage. RA can occur in all age groups.
What happens in total knee replacement surgery?
Metal platforms are secured to the tibia (shin bone) and to the femur (thigh bone). A spacer is inserted between these two metal implants to serve as your new cartilage. The surface of the patella (knee cap) is resurfaced or may be replaced. These new parts move freely and smoothly against each other.
What happens in total hip replacement surgery?
Damaged cartilage and bone are removed from the hip joint. The head of the femur (thigh bone) and the socket into which it fits are replaced with artificial devices. These new parts move freely and smoothly against each other.
How long does total joint replacement surgery take?
Total operating time is about 45 - 90 minutes. The time elapsed from entering the operating room to exiting into recovery is one to two and a half hours. This time includes anesthetic induction, positioning and surgical site preparation; it is not all “operating time.”
