I also have that Patella Femoral disease in my knees, from soccer. As well, I have Osgood - Shlater or something like that in my knees as well. Damn running from the age of 8 just kills you.
I've broken 6 fingers playing goalie in soccer, my elbows can dislocate on their own from throwing, I broke my foot skateboarding, and broke my nose twice wrestling.
Yes, I used to wrestle. Shut up. Wrestling was fun.
