Except for increased anterior-posterior knee laxity, results from this study indicated female athletes and male athletes were not similar with regard to predictors for first-time noncontact ACL injury.

Researchers identified 109 high school or collegiate-level athletes with ACL injuries. Investigators used multivariate conditional logistic regression to analyze patients with ACL injuries and 227 matched controls and examined the effects of demographics, joint laxity, lower extremity alignment, strength and personality traits on the chance for an ACL injury. With results from the multivariate logistic regression, investigators created risk models.

Results from the risk models indicated that in male athletes, predictors for an ACL injury included an increase in anterior-posterior displacement of the tibia relative to femur, posterior knee stiffness, navicular drop and decreased standing quadriceps angle. Investigators noted the predictors for ACL injury in female athletes were a combination of having a parent who had sustained an ACL injury and increased anterior-posterior knee laxity and BMI. by Monica Jaramillo
