Devices. 2017;11(4):041005-041005-5. doi:10.1115/1.4037261 Figure Legend: The knee testing machine used for the kinematic analysis. The test total knee components were 3D printed and mounted on 3D printed bones. A metal rod AX was fixed in line with the circular axis of the femur. AC, axial compression forces; ST, horizontal forces to apply shear or torque to the femur. The medial collateral ligament (MCL) and lateral collateral ligament (LCL) consisted of elastic cables anatomically positioned and pretensioned to 75 N. FL, femur flexed using cables; T, targets to track motion with digital camera.
