Key Role of the LCF

In the experiments conducted on the pelvis-femur-muscle-ligaments model, we found that when the contralateral pelvic drop occurs, the ligament of the head of femur become maximally tense; simultaneously, there is relaxation and lengthening of the gluteus medius muscle; the pelvis spontaneously rotates towards the stance limb (forward), and the load on the hip joint decreases. Thanks to the functioning of the ligament of the head of femur the walking is smooth, rhythmic, and energy-efficient.
