HI.. thanks to a doctor doing a bad job, at 47, I had my first knee replacement., he only did a partial, because "I was so young".. needless to say, three weeks later another doctor had to put in a full replacement, and 9 surgeries later, I now have a bad infection also.. this is over an 8 year span. I was told today when I went to see a dr on an emergency time visit (I see the knee dr on Tuesday) because I have been in such pain. I thought it was the starting of a Bakers Cyst because of the swelling and lump. The dr said no because there was nothing there to cause that. He told me that IF I had an infection (did the blood work and the two tests, for infection came back high) he said that what would happen would be that I would have to have emergency surgery, they would go in and take out the fake knee, but some kind of block in so that the knee would not bend until the infection went away, then do another (3rd) replacement. I broke down and started to cry..
