Andrews, a Birmingham, Ala.-based orthopedist for elite athletes, says preventing Brady's infection was nearly impossible, no matter how good the doctors are.
Andrew spoke as part of a medical panel on Wednesday that said doctors are seeing more children - especially girls - suffer knee injuries as they spend more time playing sports without time off.
Brady was injured in the Patriots' 2008 season opener and has not given a timetable for his return to the field.
