fyi-one of my good friends is a med student applying into ortho at penn-apparently AOA was a req for interview in the past but is not any longer; however, with that being said, there is a very large emphasis placed on AOA there according to him per the residents. just ask around and i'm sure you'll find a disproportionately large amount of people are AOA relative to other programs you may see where it may be 50/50 or so...
