keeneau,

If you haven't had surgery yet, please make sure to get your leg(s) in shape ahead of surgery, and then start PT immediately after surgery (they'll have you take a short walk with a PT and a walker in the hospital before they release you).

Do these things and it's unlikely you'll develop scar tissue. Once scar tissue forms, it creates a problem that can't be fixed with therapy alone.

All the best,

Joe
