Two previous studies have examined the association between an increased posterior tibial slope and anterior cruciate ligament (ACL) injuries as measured on plain radiographs. The study results were contradictory, with 1 reporting a statistical difference and the other showing no association. ⋯ Despite the identification of an increased posterior tibial slope as a possible risk factor for women, more research that combines the multifactorial nature of an ACL injury must be performed.

The geometry of the tibial plateau has been largely ignored as a source of possible risk factors for anterior cruciate ligament injury. Discovering the anterior cruciate ligament injury risk factors associated with the tibial plateau may lead to delineation of the existing sex-based disparity in anterior cruciate ligament injuries and help develop strategies for the prevention of anterior cruciate ligament injuries regardless of gender. ⋯ A combination of increased posterior-directed tibial plateau slope and shallow medial tibial plateau depth could be a major risk factor in anterior cruciate ligament injury susceptibility regardless of gender. Different injury risk models may be needed for men and women as other key risk factors are identified.
