Your hip joint is the most flexible joint in your body and allows you the greatest amount of movement. When the cartilage on the ends of your bones is damaged or wears away, it can be replaced by a procedure called total hip replacement. The damaged bone and cartilage are completely removed and replaced with an artificial joint, also known as a prosthesis.
The prosthesis replaces the ball joint with a metal or ceramic ball attached to a metal stem that is inserted into the femur (thigh bone). A metal cup lined with plastic or ceramic is placed in the pelvis to replace the “socket” part of the joint. The prosthesis, along with regular exercise, will allow for you to move smoothly again for many years. Be sure to ask a member of your orthopedic care team if you have any questions.
