Hip Revision Arthroplasty Information

The majority of patients who receive a hip replacement will retain the prosthesis for 15 to 20 years and sometimes for life. This is especially the case for elderly patients. However, some patients may need one or more revisions of a hip replacement. Revisions are most common in patients who had a total hip replacement at a young age and hip replacement patients who lead a very active life.

Depending on the damage to the hip prothesis and the circumstances, a hip revision can involve part or all of your previous hip replacment needing to be revised. Thus hip revision operations vary from minor adjustments to a more significant surgery. The surgery can vary from a simple liner exchange to changing one or all of the components of the previous hip replacement. Extra bone (cadavar bone) may be needed to compensate for any bone loss.

The most frequent reasons for hip revision arthroplasty include:

  • Repetitive dislocation and instability: This involves the hip popping out of place and can cause significant pain and distress.
  • Mechanical failure (implant wear and tear, loosening, breakage): This will usually present as pain and can be identified by an x-ray.
  • Plastic (polyethylene wear): This is one of the simpler revisions as only the plastic insert is replaced.
  • Infection: This will usually present as pain but other symptoms can include acute fever or a general feeling of being unwell. 
  • Osteolysis (bone loss): This can occur if particles are released into the hip joint and can result in bone being broken down and destroyed.
