Acls are almost flesh wounds these days unless you develop the "arthritic knee/bone on bone" condition (Todd Gurley). Here's a name from the past. Remember Dominack Davis? He developed the same knee condition that I believe Todd Gurley now has.. He tried to run on it and after one season on that knee he hung up his cleats.. Maybe Gurley's isn't as severe, but he definitely has a microfracture surgery coming in his near future.
