Hello there,,,
Well there are options available for genu vagum/knock knee without surgery as well...through vigrous exercises,developing the collapsed arches of foot and screw bracing...however all of this depends upon the angle of your knock knees.
Please get back online with uploaded pictures of your knees in leg straight position and also if you have Xrays if any.
A proper guidance and treatment advice can then be given on actual visual appearence of the knees.
Regards.
