Abstract
A ligament graft-fixing apparatus has a rod-shaped shaft and a ligament graft-fixing unit that can be removably mounted on the rod-shaped shaft. The ligament graft-fixing unit has a screw part which drills a bone to form a tunnel therein to hold the ligament graft-fixing unit in the bone tunnel; a ligament graft-holding part; and a mounting tunnel in which the rod-shaped shaft is mounted. The mounting tunnel and the rod-shaped shaft have a torque transmission mechanism which transmits a rotational force imparted to the rod-shaped shaft to the ligament graft-fixing unit; and a removal prevention mechanism which holds the ligament graft-fixing unit on the rod-shaped shaft.
