Abstract: Hinged external fixators are used in knee dislocation treatment, where they have shown their effectiveness. They are proposed as a technique to protect ligament reconstructions while allowing early postoperative rehabilitation. A hinged external fixator usually consists of two rigid links connected to each other by a revolute joint. Each link is then fixed to the femur and tibia, via direct pin fixation. A single-axis hinged external fixator thus well accommodates the main knee movement, i.e. the flexion and extension. This paper presents an investigation on the conceptual idea of a double-axis hinged external fixator for the human knee, which accommodates for both flexion-extension and longitudinal internal-external rotation of the tibia respect to the femur. The potential advantage of such a design is foreseen in the increasing range of motion in postoperative knee rehabilitation and a better accommodation of natural knee motion.
