Hip replacement, also called total hip arthroplasty, is a surgical procedure to replace a worn out or damaged hip with a prosthesis (an artificial joint). This surgery may be considered following a hip fracture (breaking of the bone) or for someone who has severe pain due to arthritis.
Various types of arthritis may affect the hip joint. Osteoarthritis, a degenerative joint disease that affects mostly middle-aged and older adults, may cause the breakdown of joint cartilage and adjacent bone in the hips. Rheumatoid arthritis, which causes inflammation of the synovial lining of the joint and results in an excessive synovial fluid, may lead to severe pain and stiffness. Traumatic arthritis, arthritis due to injury, may also cause damage to the articular cartilage of the hip.
The goal of hip replacement surgery is to replace the parts of the hip joint that have been damaged and to relieve hip pain that cannot be controlled by other treatments.
