Total Hip Arthroplasty
Total hip arthroplasty is the complete replacement of a damaged hip with a prosthetic one. This surgery is performed to relieve pain and restore function to a hip deteriorated by osteoarthritis, rheumatoid or psoriatic arthritis, avascular necrosis, congenital abnormalities or traumatic injury. Total hip arthroplasty involves replacing the entire diseased joint, composed of the natural ball and socket and its protective cartilage. The damaged joint is replaced with a prosthetic hip, usually made of a metal ball and a plastic socket.
The artificial hip will help the patient to move more normally and without pain. While total hip arthroplasty has a very high rate of success (90-95 percent), this surgical procedure is normally considered only after more conservative treatments have proven ineffective.
