The tendon threader includes a straight tubular body, with a handle arranged on one end, and the other tube end includes a pair of aligned wide longitudinal slots formed, with tube end remainder portions adjacent to which wide longitudinal slots each having a small longitudinal slot formed therein, the small slots for receiving a tendon, or a suture sewn onto the end of a tendon, fitted therein, forming a loop across the tube end. The tendon threader is for insertion into the straight ligament tunnel to where the tendon or suture loop is proximate to a ligament tunnel section end. Which procedure may be observed on a fluoroscopic monitor or utilizing an arthroscope fitted in the tendon threader tubular body, with a surgeon turning a pin into the side of the patient's knee, that travels through the ligament tunnel section and through the tendon or suture loop. The tendon threader is then removed leaving…
