Maybe it wasn't really clear what i meant with it (because my english is terrible) so im trying to explain it a bit better.^^
The only way that i know to get a leg like that is having knock knees:
And that is currently what you have, because of the Z rotation on the leg:
Hope it is now more clear. Of course if it was your intentional to making a leg for a reason a knock knee than it would be fine but i dont think it was the direction that you want to go with that character.
