Well they look kind of bowed but even if they are correcting them will give a a cm or two TOPS. Not going to make a big difference on your life.
Plus after they correct it they will not medically cover you lengthening anymore than what was needed to correct the deformity.
Although I would have to say there isn't really any noticeable deformity. It could just be how your legs look, my friend looks like he has bowed legs but that is just how his legs look like.
You'd be able to know for sure by getting x-rays and going to your local physician.
Really only a cm or two? That stinks, I was hoping for at least 3-4 inches.
