Abstract
A graft caliper provides for a first member having a first pick at its distal end and its proximal end attached to a handle. A second member of the graft caliper is disposed above the first member and has a second pick at its distal end that extends beyond the first pick. The proximal end of the second member is attached to an adjuster which causes the second member to move from a first position to a second position in order to change a distance the second pick extends beyond the first pick. The graft caliper provides for an indication of at least one metric for describing the distance the second pick extends beyond the first pick and places an identifier on a surface of bone representing the location of a tunnel to be formed through a femur, tibia or any other anatomical structure.
