Specializes in Orthopedic Surgery

Depends: The components are the same as any other hip replacement (except made of metal - cobalt chromium): an acetabular cup, and a femoral head which is attached to a femoral stem. Usually the first sign of problems would be localized pain and sweling. If the problem persists, then systemic symptoms may occur such as altered mental status. Have a frank discussion with your surgeon about your concerns.
