exactly...with an injury like this it does not matter how much of a fitness freak you are. Even though the injury can be treated it will never be 100% as there will be permenant damage.
My mother used to be a crazy fitness health freak who jogged daily went to aerobics weekly and also enjoyed rock climbing as her hobby. One day she was turning to put groceries into the trunk of the car and for some freak reason she broke the bone below the knee in 9 different places before she even hit the ground(then dislocated her shoulder). That was 3 years ago and after 7 surgeries she still walks with a limp and a cane...Bit more then tearing the ACL though.
