Hip replacement surgery is all about replace a worn-out or damaged hip joint. This surgery may be a choice after a hip fracture or for severe pain because of arthritis. It helps relieve hip pain that can’t be controlled by other treatments. In a hip replacement surgery a surgeon removes the damaged sections of your hip joint and replaces them with parts usually constructed of metal, ceramic and very hard plastic. Hip replacement surgery might be an option for you if your hip pain interferes with daily day to day activities. Nonsurgical hip treatments haven't helped someone much further. Arthritis damage is the most common reason to need hip replacement.
