Total Hip Replacement: Frequently Asked Questions
About Total Hip Replacement
What is arthritis and why does my hip hurt?
In the hip joint there is a layer of smooth cartilage on the ball of the upper end of the thigh bone (femur) and another layer within your hip socket. This cartilage serves as a cushion and allows for smooth motion of the hip. Arthritis is a wearing away of this cartilage. Eventually it wears down to bone. Rubbing of bone against bone causes discomfort, swelling and stiffness.
What is a total hip replacement?
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 ball is replaced with a metal ball that is fixed solidly inside the femur. The socket is replaced with a plastic liner that is usually fixed inside a metal shell implanted into the pelvis. This creates a smoothly functioning joint that does not hurt.
