Do I really need surgery? There several things that will affect this answer. Do you plan on playing sports or are you happy giving them up and doing things less stressful on the knees? If you can give up the sports that are rough on the knees, you might get by without surgery. Does your knee "go out" a lot? If it does and you have little control over it, surgery would probably be your best bet. If you would like to try rehabbing your knee and wearing a brace to see if that works, go ahead. Ju.
