The
ankle joint was dorsiflexed at 5[degrees]/s starting from 30[degrees] of plantar flexion, until the passive resistive torque corresponding to 20% of the pre-measured maximal voluntary plantar flexion torque was reached.
These muscles were selected due to their established role in regulating static and dynamic postural stability about the
ankle joint. (3)
However, in this osteosarcoma case report, it was not a total tibia replacement as no total
ankle joint replacement was made, since part of the distal tibia was not removed.
Additionally, the large number of ligamentous structures and overall strength of the ligaments provide significant supplemental stability to the
ankle joint articulation.
(10) In this case, ankle instability, major concern in these fractures should be the restoration of the stability of the
ankle joint by repair of the ligamentous elements.
To evaluate the mechanical properties of the
ankle joint, the ankle dorsiflexion angle and
ankle joint passive torque were measured sequentially, and the muscle-tendon complex stiffness was calculated from these parameters.
Left ankle angle: the left
ankle joint is the peak, the heel of the left foot and left knee joint respectively forms two lines with the left
ankle joint;
These injuries are of utmost importance as the ankle transmits the whole body weight and the stability of
ankle joint determines the locomotion.
To evaluate active and passive
ankle joint position senses, 10[degrees] and 20[degrees] of ankle inversion and 15[degrees] and 30[degrees] of ankle plantarflexion were selected as the test angles.
Their
ankle joint, however, allows only the updown motion of the foot.
