Decreased Ankle Dorsiflexion is Associated with Dynamic Knee Valgus

A proposed biomechanical explanation is that restricted ankle joint dorsiflexion directly results in overpronation of the foot, which causes internal rotation of the lower extremity, which strains the external/abductor musculature, which can then no longer prevent femoral adduction; hence genu valgus.
