Hi Everybody,I have another question. I've read a few posts about revision. Is this a surgery to fix or make adjustments to the knee replacement parts? Why is this revision surgery done?

The biggest issue about lower limb joint replacements is that they can wear out. Time is a big question - some say 10-15 years, others 15+ though I know of patients who have had their knee/hip in for 20+ years with no problems.
What wears varies; in a metal or ceramic on plastic, it's the plastic, in ceramic or metal - well, unsurprisingly it's the ceramic or metal!
Sometimes, and if the base implants are still sound, the metal liners/inserts can simply be changed. But if there is any wear, loosening or other damage to them then the entire joint has to be removed and a totally new one inserted. If this is because of the aforementioned problems, then the prostheses can be removed and reinserted in one go. And if cement is use, it can just be reamed out and new cement put on top of the old.
However, if there is infection involved then the leg may need a period without any prostheses in it whilst the infection is eradicated and the every scrap of the old cement has to be removed before a new one is put in.
That, in a nut shell, is what revision is all about.
