I tore my ACL twice, once alpine park skiing trying to show off as a stupid teenager and once playing rugby when someone fell on my leg badly.  I still have no ACL (second reconstruction was deemed high risk low reward basically) and I have absolutely no trouble with housework.  Do have to be slightly careful about how I pivot my weight, when doing something like playing tennis or basketball, or more alpine skiing. Side note: PT is by far the most important factor in recovery from these injuries.  PT is based on restrengthening the muscles to compensate for the weaker/healing tendon and help stabilize.  And by strengthening I mean slightly above a normal healthy muscle.  There is zero chance this cow doesn't reinjure/exacerbate the problem.  This could be the beginning of a (brief lol) lifelong condishun
