INVENTOR: ANDREW STROKON TITLE: APPARATUS AND METHOD FOR KNEE SURGERY A graft comprising a section of patellar tendon and sections of its boney attachment at either end is harvested using an apparatus comprising 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. A sliding block on the track has bores at right angles to the stem to accommodate the fixing pin which, in a first step of the operation, can be inserted through the bone to abut the stem before the apparatus is withdrawn so that the boney plug of the graft can be inserted in the canal and then the pin can be driven home to secure the boney plug in position. 7757S/HM |
