Got to have right knee replaced now!!

Went to see my knee consultant, but rent-a-consultant was there as my Knee consultant was on holiday!! Discussed my right knee as it has been getting more and more painful. He sent me to have several x-rays so he could take a look at how it is now and we didn't expect to see what it showed. He showed me the last x-ray I had on the right knee in December and what it looked like now and it was a shock! The knee had got a heck of a lot worse! Then he showed me the M.R.I of the right knee taken last September and there is a hole in the knee bigger than the one that was in the left knee before it was replaced! So needless to say I have now been put on the list to have the right knee replaced!! The waiting list is currently 5-6mnths but we are hoping a cancellation will come up and it can be done sooner.
