  • Publication number: 20120239044
    Abstract: A guide that facilitates the creation of two bone tunnels for use during a “double bundle” cruciate ligament repair. In the case of an anterior cruciate ligament repair the guide facilitates the formation of two tibial tunnels extending between a single aperture on the anterior tibia and two distinct apertures on the tibial plateau. The guide has a single angled throughbore for guiding a drill bit on a predetermined angle relative to the anterior portion of the tibial tunnel. In an alternative embodiment the guide has two independent and non-intersecting bores which allow the simultaneous placement into the tibial tunnel of two separate guide pins to guide the formation of two tibial tunnels on the tibial plateau.

  • Publication number: 20070270857
    Abstract: The subject invention is a fixation device or anchor intended to secure a graft ligament or other soft tissue repair. The device is designed to be attached to a graft ligament and to secure the graft within a bone tunnel by extending transversely across the opening of the tunnel. In certain procedures the device is intended to pass through a bone tunnel in an orientation generally aligned with the tunnel and then turn transversely. The device has an inherent tendency to rotate upon exiting the tunnel to thereby become automatically transversely aligned with the tunnel and the graft ligament. The rotation is due to a moment automatically created as a resultant of forces applied to the anchor by a pulling-suture via a laterally offset aperture joining the pulling-suture to the anchor.
