Apparatus and methods for use in performing surgical operations such as anterior or posterior cruciate ligament reconstructions wherein the apparatus has means for positioning a target area at the center of an arc of a circle so that when the target area is positioned at a location relative to the anatomical center of the original attachment of the cruciate ligaments on the tibia and femur bones, kirschner wires may be pushed through guide means having a longitudinal axis coinciding with a ray emanating from the center of the circle and indicate the proper location for holes in the tibia and femur for the proper attachment of a cruciate ligament graft substitute. The apparatus is also used in the placement of kirschner wires to serve as guide wires in the performance of an osteotomy.
