ACL tear? Blame your parents
If you haven’t heard the news, ACL tears are genetic or at least, predisposition to tears is. You can find the study here, published in the British Journal of Sports Medicine: http://bjsm.bmj.com/content/44/12/848.abstract
or if you prefer, it is discussed in the New York Times here:
http://well.blogs.nytimes.com/2010/09/29/phys-ed-are-bad-knees-in-our-genes/?scp=1&sq=acl&st=cse
Its about female twins, but the data has implications for everyone. Basically, if you are like me and have really flexible knees, it could have contributed to your ACL tear (or in my case, both my ACL tears). If you are like Henry, with a mother and father who tore their ACLs, then it is just another thing you inherited from your parents. My parents never tore their ACLs, though my aunt did (and she opted, instead of surgery, to never do any strenuous activity ever again! – Really!).
But, like most genetic traits, flexible joints is likely pleiotropic say the authors of the study, meaning that lots of genes contribute to that trait, not just one or two. Regardless, next time you see your parents, you could let them know what they did to you 
Or in my case, fear for my children
