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.
