Yes, despite some of the other stuff you really can get a lot of info here & sometimes a push in the right direction.
I am back from taking my 13yodd to the orthoped. doc. Diagnosis is "knock kneed". There is a fancy word for it but I can't remember it.
She has to wear a brace in PE or anything that will overwork her knee, like sports, bikes, or walking for long periods like the zoo or something.
In addition she has to exercise her hamstrings for several months 6 times a week, working her way up to 10lbs on each leg.
Doctor said that it is a process and will probably take at least 3-4 months or more.
She is so happy to finally figure out what it is as well as I am. She has been living with this for a very long while.
