What causes the need for a total hip replacement?

Total hip replacement (THR) is an established, long-lasting surgical procedure which has demonstrated excellent outcomes in relieving the pain associated with hip arthritis. The decision to proceed with hip joint replacement surgery is yours and does not need to be rushed. You should take time to consider whether joint replacement is right for you. The hip is a ball-and-socket joint. The ball is formed by the top of the thigh bone (femoral head) and the socket is formed by the bony pelvis (acetabulum). The joint is lined by hyaline cartilage, which is smooth and allows for frictionless movement. Degeneration of hyaline cartilage results in osteoarthritis, with increasing friction between the bones resulting in pain and stiffness. Hip replacement is most commonly performed for hip osteoarthritis, but can also be used to treat rheumatoid arthritis, osteonecrosis, or a hip fracture.
