Hip replacement surgery is a procedure used to treat severe hip damage, usually when pain and stiffness affect walking, sleep, work, or daily activities. During the operation, the damaged parts of the hip joint are removed and replaced with artificial components designed to improve movement and reduce pain. According to NHS patient guidance, hip replacement may be recommended when hip pain and reduced mobility significantly affect quality of life.
The hip is a ball-and-socket joint. The rounded head of the thigh bone moves inside a socket in the pelvis. Healthy cartilage allows smooth movement. When cartilage becomes damaged or worn, movement becomes painful and stiff. This is why advanced hip arthritis is one of the most common reasons for hip replacement surgery.
