  • Ligament graft protection apparatus and method
    Patent number: 5658289
    Abstract: A graft protection device suitable for protecting a bone-tendon-bone graft used during anterior cruciate ligament reconstruction. The graft protection device comprises a distal blocking member, a proximal releasable holding sleeve and an elongated connecting portion connecting the blocking member with the holding sleeve. A radially extending handle is attached to the holding sleeve in order to enable a user to longitudinally and rotationally position the graft protection device along the shaft of an elongated driver when the device is inserted through an opening into a joint.

  • Angled surgical screw driver and methods of arthroscopic ligament reconstruction
    Patent number: 5391170
    Abstract: A surgical screw driver for inserting bone screws in bone tunnels in ligament reconstruction has, in a preferred embodiment, a rotatable operating shaft disposed at an angle to a drive shaft. A mechanism is on the drive shaft for retaining a bone screw. Methods of arthroscopic cruciate ligament reconstruction include the steps of introducing a surgical screw driver through a portal that is offset from the longitudinal axis of a bone tunnel and driving a bone screw mounted on the driver in the bone tunnel to fixate a bone block in the bone tunnel.
