Differences in Knee and Hip Adduction in Runners with Iliotibial Band Syndrome

This study seems to show a relationship between iliotibial band (ITB) syndrome and knee adduction (genu varum) and the activation of the TFL. A relationship can be two incidents that occur together, termed a “coincidence.” Or there can be a causal relationship between them; i.e., one causes the other to occur.

Genu Knee Valgus

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.
