23 year old female with knock knees all my life what can i do to correct it?

See an Orthopaedist: Many females have a mild to moderate "knock-knee" or valgus alignment at their knees. This may be due to the natural alignment of your knees- but may also be influenced by the development of your hips. An orthopaedic evaluation with x-rays is the best place to start to help identify if their is a true problem and recommend treatment to help.
