Abstract: A method of cruciate ligament replacement using a graft having a section of patellar tendon and sections of its boney attachment at either end harvested with an apparatus having a dowel cutter and a mounting device for the dowel cutter, the mounting device having an arm rigidly interconnected with means for rotatably mounting the dowel cutter, the arm extending to a remote location at which it is adapted to be secured, e.g. by pins, to boney structure located beneath the arm. A second apparatus is used to permit accurate guiding of fixing pins through a tibia or femur and comprises a rigid track and a cylindrical stem at right angles to the track and adapted to be inserted in a drilled canal in the bone.
