arrrr! i am a young dancer and was wondering if there is any hope for me as i have knock knees!?!

Hello, young*hopeful, and welcome to CriticalDance! Of course, we don't know your age or how slight or how severe your condition of knock knees. Many children who have mild knock knees (and I was one) do see their legs straighten as they mature. I wore special shoes for a couple of years. Perhaps orthotics might be recommended. The best advice would be for you to see a doctor who specializes in sports medicine for an evaluation.
