Abstract
A method for forming a straight tunnel to endosteally intersect a straight anterior cruciate ligament tunnel that utilizes a sight barrel arthroscopic instrument for use in a knee cruciate ligament procedure for forming a passage into the femoral endosteum to inersect, at an acute angle, the straight anterior cruciate ligament tunnel. The instrument references the anterior cruciate ligament tunnel to guide drilling of a passage from a point in the roof of the intercondyle notch to intersect the ligament tunnel in the femur endosteum. Which passage is for receiving a fastener, such as a set screw, interference screw, or the like, that is installed into or alongside a ligament graft that is fitted in that anterior cruciate ligament tunnel, providing an endosteal fixation of which ligament graft in the femur endosteum.
