Abstract:
1. A method of selecting a femoral prosthetic for implantation relative to a femur using a femoral sizing guide, the method comprising: placing an extension portion of the femoral sizing guide adjacent to a posterior condyle surface of the femur, the extension portion having a base portion pivotally connected thereto; locating a stylus proximate to an interior condyle surface of the femur; moving a first actuator disposed between the extension portion and the base portion to rotatably displace the extension portion with respect to the base portion until the stylus is centrally located on top of the interior condyle; identifying a measurement of the femur with the sizing guide based on a relative location of the stylus, the extension portion and the base portion; and selecting a femoral prosthesis based on the measurement; wherein moving the first actuator comprises rotating a worm gear disposed between the extension portion and the base portion.
