  • Orthopedic device having a dynamic control system and method for using the same
    Patent number: 9539135
    Abstract: An orthopedic device and method for using the same are provided for applying a dynamic load on a leg of a user. The orthopedic device has a rigid or semi-rigid frame including lower and upper frames, and a hinge assembly connecting the lower and upper frames. A dynamic loading component is used to urge the load on the user's leg on the basis of flexion of the hinge assembly on the basis of tension in an elongate element connecting the dynamic loading component and at least one of the lower and upper frames. A peak load is generated at a flexion angle between extension and flexion of the hinge assembly.
