    Abstract: Endosteal fixation of a ligament graft with an interference fixation device installed in a retrograde manner in ACL reconstruction is disclosed. The interference fixation device may be a screw or a ribbed implant fitted with a length of reinforced suture or wire for pulling the interference fixation device through the tibial tunnel. The suture extends beyond the leading tip of the interference fixation device a sufficient length to allow the interference fixation device to be passed into the joint by pulling on the suture or wire exiting the tibial tunnel. A driver or an impaction device, such as a slap hammer, is employed to advance and insert the interference fixation device in a retrograde manner into the tibial tunnel. Accordingly, interference fixation of the graft near the tibial plateau is provided, thereby eliminating graft abrasion at the tibial plateau tunnel opening.

    Abstract: A system and method for more efficient cleaning and sterilizing of surgical handpieces by using a removable valve assembly. The valve assembly is removable to provide access to a first suction passageway and a second suction passageway for cleaning purposes. The valve assembly has a protrusion that engages with a handpiece to secure the assembly to the handpiece. The protrusion of the valve assembly may also be retracted into the valve assembly to allow the valve assembly to disengage the handpiece thereby allowing the valve assembly to be removed from the handpiece. The first suction passageway may also be removable.

    Abstract: Endosteal fixation of a ligament graft with an interference fixation device installed in a retrograde manner is disclosed. An interference screw is installed at the top of the tibial tunnel, through the tibial plateau, in a procedure for ACL reconstruction. The interference screw is fitted with a length of suture for pulling the screw onto a driver placed through the tibial tunnel. The suture is secured to the screw using a knot, an adhesive, insert molding, and equivalents. The suture extends beyond the leading tip of the screw a sufficient length to allow the screw to be passed into the joint by pulling on the suture exiting the tibial tunnel. A driver fits into a drive opening in the leading front end of the screw. Turning the driver advances the screw in a retrograde manner into the tunnel. Accordingly, interference fixation of the graft near the tibial plateau is provided, thereby eliminating graft abrasion at the tibial plateau tunnel opening.

    Abstract: A bone drill that includes a shaft with a flexible portion having a proximal end and a distal end and a drill tip coupled to the distal end of the shaft. The bone drill also includes a cannulated sheath with a proximal end and a distal end, the sheath housing a portion of the shaft and having a curved portion at the distal end. The drill tip may also be housed within the curved portion of the sheath. The bone drill may also include a hub with an actuator mechanism, the hub being coupled to the sheath, wherein the actuator mechanism retracts the sheath to cause the drill tip to extend beyond the distal end of the sheath.

    Abstract: Endosteal fixation of a ligament graft with a bioabsorbable interference screw installed in a retrograde manner in ACL reconstruction. The bioabsorbable interference screw is insert-molded with a length of suture extending from the distal tip of the screw for pulling the interference screw into the joint and into position for retrograde insertion at the top of the tibial tunnel. The interference screw has a cannulation extending partially through the screw from the leading tip. The cannulation is shaped to receive a correspondingly shaped driver. The driver is inserted into the tibial tunnel to engage the screw. By turning the driver, the interference screw is turned into the tibial tunnel in a retrograde manner. Accordingly, interference fixation of the graft near the tibial plateau is provided, thereby eliminating graft abrasion at the tibial plateau tunnel opening.
