A total knee replacement surgery involves the removal and replacement of damaged bone and cartilage. Damaged tissue is replaced with artificial components made from metal and plastic. The procedure is often recommended when one suffers from an arthritic condition, such as osteoarthritis or rheumatoid arthritis, which causes the cartilage around the bones to wear away or become inflamed.
A unicompartmental knee replacement, or partial knee replacement, refers to a procedure in which a part of the knee is replaced with prosthetic components. I may recommend this procedure in cases where damage or disease affects one area of the knee. The surgery is generally very successful and provides motion closer to your native knee. There are specific prerequisites that need to be met before this procedure will be considered.
