Revision Hip Replacement

what is revision hip replacement surgery?

Occasionally, it may become necessary to replace all or part of a prosthetic hip. This procedure is known as revision hip replacement surgery. This involves removing all or part of the old prosthesis, re-preparing the damaged bone ends and then attaching new prosthesis to them. A revision hip replacement can involve different types of implants to those used during the original surgery in order to help support and/or replace damaged bone.

The liner can be exchanged leaving the other components in place if they are well fixed.
  • Loosening of either the femoral or pelvic (acetabular) components
  • Infection around the prosthesis
  • Dislocation – this is where the hip joint pops out of the socket
  • Osteolysis (bone loss)
