What Is Joint Replacement?
Joints are formed by the ends of two or more bones connected by cartilage, which serves as a protective cushion, allowing smooth, low-friction movement of the joint. If the cartilage becomes damaged by disease or injury, the tissues around the joint become inflamed, causing pain. With time, the cartilage wears away, allowing the rough edges of bone to rub against each other, causing more pain.
When only some of the joint is damaged, a surgeon may be able to repair or replace just the damaged parts. When the entire joint is damaged, a total joint replacement is done.
Why Joint Replacement?
A common reason for having a hip or knee replaced is osteoarthritis, rheumatoid arthritis, or loss of bone by poor blood supply. For more information, see links below.
