[Model investigations on the static abnormal strain on the homolateral knee joint following arthrodesis or ankylosis of the hip joint in the frontal plane (author's transl)].

The static abnormal load on the homolateral knee joint after stiffening of the hip in the frontal plane (abnormal load associated with abduction or adduction) is examined via a simplified pelvis and leg model. Besides the direct impairment of the homolateral knee joint, it has also been possible to demonstrate the indirect impairment of the ankle joint and of the foot.
