They first attack the triad from a sociological perspective, warning readers that decades of progress of women in sports is at risk owing to “the creation of yet another form of female specific pathology”. They are concerned that “Triad related data may be misinterpreted and used as justification for setting health and social policies that may ultimately counter the US Public Health Service efforts to promote the benefits of athletic participation and an active lifestyle among children and adolescents”. Using this logic, researchers and health professionals should abandon their efforts to understand and prevent anterior cruciate ligament injuries in women, which occur at a rate of 6–8 times that in men,² for fear that attention to this “female specific pathology” would discourage participation in sports.
