I broke it nearly 4 years ago when i was hit by a car. I had 3 operations on it in total, including a ski graft. One operation was simply to remove the wires that held it together. I had trouble with it until early last year, but now I can walk, run, dance etc comfortably with no trouble. I know you can't say "Yes it will definitely stop you passing the medical", but some examples or advice would be appreciated.
