My son had ACL surgery many years ago. It pretty much finished his soccer and football careers. If you play any sports count on being out for a year. He was back up and walking in a couple of days but any twisting or side to side movement is a no no! Exercise bicycle helps as soon as you can deal with it. He had a custom knee brace made which came from California, I assume that now they are available in Canada. It helped a lot as far as day to day getting around for the first month or two and held the knee stable in case he slipped or fell. It was expensive but worth every penny. Good luck with the surgery if you want to know any finer details of the surgery PM me.
