Revision Hip Replacement
What is a revision hip replacement and why is it necessary?
Your first joint replacement (hip or knee) is called your primary procedure. The artificial joints like our native joints will wear out in time and require a re-do or “revision” procedure.
The Australian joint registry data suggests that approximately 6-7% of joint replacements will require revision surgery by 14 years because there has been a problem. That means after 14 years the majority of joint replacements (ie 93%) are still working fine. The problems that occur which require revision include:
- Loosening of the implants away from the bone
- Recurrent Dislocation (usually in hips not knees)
- Implant breakage
- Worn out plastic or metal
Revision joint replacement is difficult major surgery that requires extensive planning and investigation. Essentially it involves replacing all the components with new ones to give the patient a pain free functioning joint again. In addition to this the surgery needs to address the reason for failure eg. Eradicate infection, fix fracture. Younger patients tend to be more active and hence wear out their artificial joints sooner than others. This is backed up by data in the Australian joint registry which shows a higher revision rate in younger patients. For this reason surgeons try and delay joint replacement surgery for as long as possible wherever possible.
