What can i do about my knock knees? any treatments?

Do they hurt?: "knock knees" or genu valgum usually stems from your anatomic built which can only be changed with osteotomies (breaking and realigning bones), reserved for severe symptomatic cases. Pt to strengthen the leg muscles can be helpful but won't change your bone alignment orthotics can also provide subtle changes to your mechanics.

Depends on age: If very young, sometimes leg braces will help. If older the only alternative would be surgery if you are haveing problems.
