The invention is in a cross pin and set screw femoral and tibial fixation apparatus and method for mounting a ligament graft that, in one embodiment is a bone tendon bone type ligament graft and in another embodiment is a soft tissue ligament graft, in femoral and tibial tunnel sections of a straight ligament tunnel formed in an arthroscopic cruciate ligament replacement procedure. The apparatus and the steps involved in its use include, a drill guide for drilling a transverse hole or holes, which drill guide is arranged to be releasable from a first twist drill so as to leave it in place, the first twist drill to be used for guiding further drilling and passage of a fastener device. A K-wire, or the first twist drill if left in place, is then used for guiding a second twist drill, for enlarging the transverse hole and is used for guiding turning of a cannulated fastener device, that is a set screw or screw, into the femoral bone end of the ligament graft that has been fitted into the femoral tunnel section, providing a cross pin mounting to the femoral bone end of the bone tendon bone type ligament graft, or, utilizing the transverse hole, the apparatus of the invention can be used to provide a cross pin type mounting of a soft tissue ligament graft that is looped over the cross pin.
