\\\to get to the damaged area the surgeon needs to break my ankle. \\\
I think that you have either misheard what he has said OR misconstrued what he said.
How long is a piece of string?
I will assume that your are not having arthroscopic removal of cartilage and in which case, you will be in a plaster cast for about 2 weeks and than a walking boot for about another month.
I do not know what your occupation is, so i cannot comment on the time you will be likely to return to work.
Hope this is helpful.
