Total hip replacement surgery almost always reduces joint pain. During this surgery, your problem hip is replaced with an artificial joint (prosthesis). A total hip replacement is an operation that removes the arthritic ball of the upper thigh bone (femur) as well as damaged cartilage from the hip socket. The damaged ball is replaced with a metal ball that is fixed inside the femur. The socket is replaced with a plastic liner that is fixed inside a metal shell. This creates a smoothly functioning ball-and-socket joint that does not hurt.
An estimated 90-95% of patients achieve good to excellent results with relief of discomfort, as well as an increase in both activity and mobility. Total hip replacement patients recover quickly and will likely be able to walk the first day after surgery.
