Abstract
An endosteal ligament fixation device for mounting to a bone end of a bone tendon bone graft for use as a replacement anterior or posterior cruciate ligament. The endosteal ligament fixation device consists of a disk, collar, ring or band that is arranged to be fitted and secured to the graft bone end that includes a number of radially equidistant spaced outwardly projecting resilient barbs or pins extending therefrom, or may involve forming radially equidistantly spaced slanted holes into the graft bone end for mounting individual resilient barbs or pins. The barbs or pins can be sharp, blunt, or otherwise configured to extend into and to hold securely within a bone endosteum. A number of which barbs or pins are set radially into the disk, collar, ring or band, or individually into the bone end so as to be angled to extend off of and are spaced apart from the bone end surface, pointing towards the tendon coupling with that bone end. The barbs or pins are to individually flex inwardly during passage along the ligament tunnel wall when the graft bone end is urged therealong. At the tunnel end, the resilient barbs or pins are to flex outwardly into the bone endosteum, seating the gra…
