Her memory of the events that led to PTSD was erased. PTSD is a severe mental condition that occurs as a result of single or repeated events that have a super-powerful negative impact on the individual's psyche. If a person has no memories of events, then consciousness cannot form any negative consequences based on what does not exist. And these documents in the hospital are the result of Asuna's examination after her father saved Asuna from Sugo. Her memory was erased, obviously, after that.
PTSD causes a negative reaction when memories are associated with a traumatic situation. If Asuna had PTSD, logically, she should be afraid of sex. It's easier to assume that the father, along with his memories, also erased some moral fears associated with sexual deviations.
p.s I've seen a lot of comments here, and I think most of the players have come to the conclusion that Asuna's personality hasn't changed. She was originally a hypocritical whore, but Kirito is too modest and passive, and she supposedly loves him, so she hid it. Inoda was just lucky that he discovered these traits of her character. Asuna, as a well-mannered aristocrat from a rich family, tries to pretend that she is a good and loyal girl, but good sex reveals her dark sides.
