Hip replacements are among the most common orthopedic procedures. When a hip replacement is performed, the arthritic, damaged hip joint is removed. The ball-and-socket hip joint is then replaced with an artificial implant. Hare are brief descriptions of some of the most commonly used hip replacement implants. Not all implants are options for all patients. A prosthetic made of metal and plastic are the most commonly used hip replacement implants. Both the ball and the socket of the hip joint are replaced with a metal implant, and a plastic spacer is placed in between. The most commonly used metals used include titanium and stainless steel.
