ORTHOPEDIC DEVICE HAVING ANTEROPOSTERIOR ARTICULATION

摘要

An orthopedic device in the form of an unloading osteoarthritic knee brace has proximal and distal frame members with a flexion-extension hinge positioned between the proximal and distal frame members. At least one articulating free hinge is positioned in an upright between the flexion-extension hinge and one of the proximal and distal frame members. The free hinge provides free rotation of the proximal or distal frame member about the anteroposterior axis with respect to the flexion-extension hinge.
