Abstract
A method for positioning a bone cutting guide on a tibia may begin with coupling a bone cut positioning apparatus with a tibia. The method may also include adjusting the positioning apparatus in a varus/valgus orientation to shine a light emitted by a light emitter approximately along a midline of an anterior surface of the tibia, swinging a pivoting arm about a pivot joint to direct the emitted light along a medial surface of the tibia, adjusting the positioning apparatus in an anterior/posterior orientation to shine the light approximately along a midline of the medial surface, contacting a stylus with a proximal end of the tibia to select a cutting depth for a bone cut to be made on the tibia, and attaching the bone cutting guide to the tibia in a position determined by the positioning apparatus.
