  • ACL reconstruction technique using retrodrill
    Patent number: 7238189
    Abstract: Methods and apparatus for arthroscopic tenodesis using sockets in bone created by retrograde cutting. A cannulated pin is drilled through bone and into a joint space in the normal, antegrade direction, guided by a drill guide. A strand provided through the cannulated pin is used to draw a retrodrill cutter into the joint space. The retrodrill cutter is threaded onto the cannulated pin, which is turned for retrograde cutting of a socket into the bone. The method is used to form a pair of sockets in the joint, which accept the respective ends of a replacement graft. The graft is brought into position in the joint space using loops formed in the strands, in a manner similar to introduction of the retrodrill cutter. The reconstruction is completed by securing suture attached to the graft ends with a button implant installed at the bone surface.
