Hello doc. i have knock knees and i'm only 12 years old. how can i fix this without going through surgery?

Knocked knees: I am too, or atleast I have significant valgus position of my lower legs. We all can not be sprinters. One thing your are twelve and because of growth this can be assentuated. You legs are likely to straighten out as you grow, but for many of us it is our nature to have legs shaped like this. If you are having troubles walking though you will likely need to see an orhtopedist for your options
