Hip replacement surgery removes a diseased hip joint and inserts a new manufactured hip joint. The most common causes of total hip replacements are damage from osteoarthritis, rheumatoid arthritis, and traumatic arthritis. When other treatment options are not successful at treating the pain and restricted motion associated with joint disease, a total hip replacement can be used to improve a patient’s ability to perform daily activities and move about. Different materials are used to make artificial hip joints, though all consist of two main components: a ball made of metal or ceramic, and a socket made of plastic, ceramic, or metal. Surgical cement may be used to fill the gap between the prosthesis and the remaining natural bone to ensure that the new joint is secure. A non-cemented prosthesis is also available and is coated with textured metal or a bone-like substance that enables young, strong bone to grow into the prosthesis.
