No, Jillio, what that means is the information isn't being remembered by implanted children in their adulthood. That doesn't mean it wasn't given to them, that doesn't mean it wasn't given to their families.
Tracking people down 10 years after surgery (or even less than 2 years after surgery, as I just did for one retrospective review) is no easy task. The people most likely to have up-to-date contact information is the manufacturers, they are the places people with implants will continue to have consistent contact as the order upgrades/supplies.
