My sister had an accident which left her right leg with 5 breaks in the calf, and a dislocated knee. She has had 6 serious operations within a few years, and will continue to have problems with her leg for her entire life. If her leg doesn't improve, then amputation is the only other option.
Count yourself lucky, it could be worse.
Anyway, as long as you're strong you should be able to cope with it. You are likely to be assigned to a specialist who can give you more information and help.
I know it's hard, but try not to let it get to you. Good luck with it all.
