Good Morning. What was the reason you had the knee arthrodesis? How long has it been? I had a knee replacement go bad 3 years ago and after 15 surgeries now have stiff leg. The original doctor would not recognize I had an infection in the knee and even after the infectious disease doctor told him if he didn''t take out the artificial knee I could die as I was so sick he wouldn't do it. I went to Mayo and they took it out the next day but have had numerous infections and now my body rejects anything foreign. If it wasn't for Mayo I for sure would not have a leg and may not be alive. Do you have much pain in your leg? I do plus my foot but doc says there is alot of nerve damage. Look forward to hearingi from you. It is so hard to find anyone with this and it will be great to share things with you.
