Abstract:
An ankle prosthesis can have a base and an upper hinge component that is pivotably attached to the base about an axis. First and second biasing elements can bias the upper hinge component in first and second rotational directions, respectively. At least one selectively extendable and retractable locking element can extend from one of the base and the upper hinge component and engage the other of the base and the upper hinge component to limit the pivotable movement of the upper hinge component.
