Other conditions, such as rheumatoid arthritis (a chronic inflammatory disease that causes joint pain, stiffness, and swelling), avascular necrosis (loss of bone caused by insufficient blood supply), injury, and bone tumors also may lead to breakdown of the hip joint and the need for hip replacement surgery.
Infection is the primary reason. Failure after many years is usually caused by osteolysis, a gradual loosening of the hip joint that comes from wear and tear on the new joint surfaces. If you experience persistent pain or weakening, your hip component may be loose.
