Revision Total Knee Replacement
Revision knee replacement involves removal of the failed primary knee replacement, together with the inflamed lining and any damaged bone beneath, and then inserting a new replacement knee.
This surgery is more complex and time consuming than primary surgery and usually involves the use of special underpinned implants supported by stems inserted into the thigh and shin bones. The back surfaces of the revision components are often built up with additional blocks to replace bone damaged by the failed replacement knee.
If the presence of infection is suspected the revision surgery is usually performed in stages, inserting a temporary knee replacement containing antibiotics until infection appears to have been controlled, and then removing the temporary replacement and inserting the revision knee replacement.
