Hello, its me again looking for some reassurance. I should apologise as I only seem to come on here when I'm after something..
I got the results of the isotope scan yesterday and it's as I feared...the entire ankle replacement is loose and apparently the pain, stiffness, swelling, loss of movement will only continue to get worse

. I have to decide when rather than whether to go for the revision surgery.
However to complicate matters slightly (I always have to be awkward), my 3 and a half year old replaced knee (on the other side to the replaced ankle) showed up a problem too. Now this replacement has always behaved slightly differently to my others in that it still swells, gets hot and gives some pain (nowhere near as bad as pre op). I have always been told that this was quite normal at my post op check ups and it would settle with time but after 3 years it was becoming obvious that this was not routine post op activity. In fact over the last few months the symptoms have got worse so I discussed this hotness, pain and swelling with my knee surgeon just a few weeks ago at an appointment. He felt that the problem related to the RA still being present in my knee cap...apparently he doesn't routinely replace the knee cap when he replaces all the other parts of the knee joint whereas some surgeons believe that the knee cap should be replaced in RA patients because of this potential problem. My surgeon said he has performed over a 1000 replacements (probably not all RA patients) and he said usually once he takes the main components of the joint away, the RA doesn't bother attacking the knee cap. I am the only person he has seen this happen in..told you I was awkward. He said 'oh you must have severe aggressive RA'...tell me something I don't know

. He feels that once the RA has destroyed the knee cap, the symptoms will subside and the replacement will be fine (he can't do much else really as replacing the knee cap now isn't an option due to the significant risk of complications).
Anyway, sorry if I'm waffling, the ankle surgeon (well actually I only saw the registrar yesterday) now wants to rule out the possibilty of an infection in either the ankle replacment (very unlikely that it is an infection rather than the age of the replacement that is causing the loosening) or the knee replacement (maybe a possibility given my symptoms???). Obviously they would not be able to do any surgical procedure if there was any infection present anywhere. He has ordered a WHITE CELL SCAN which involves more radioactive substance being put into me. I've been thinking about this overnight and I'm not entirely comfortable with it..
a) because I had a radioactive substance injected just 11 days ago...anymore and I'll be glowing in the dark soon
b) because of the risk of infection with a canula..and having blood reinjected back into me...I know its only a slight risk but with being on Enbrel I wonder how much of an increased risk there is? and
c) according to information a white cell scan can show infection AND inflammation.......so how will they determine whether its inflammation from the RA or an infection in the knee

If I did have an infection, wouldn't it be getting worse or systemic (especially with the Enbrel) or can such an infection be very low grade and remain within the joint?
Yes I should have asked these questions yesterday but after waiting in a crowded clinic yet again for 2 and a half hours (when some poor soul had an epileptic fit and another mentally disabled patient was very distressed and screaming the place down), I didn't feel too good, wasn't thinking straight and to be honest I just wanted to get out of there!
Any thoughts anyone?
Thanks for reading this...just writing my thoughts (confusion

) down and sharing with people who can understand my concerns helps.
