Abstract

The present invention has multiple aspects relating to assembled self fixing bone-tendon-bone (BTB) grafts and BTB implants. A preferred application in which self fixing assembled bone-tendon-bone (BTB) grafts and implants of the present technology can be used is for ACL repairs in a human patient. In one embodiment, a self fixing BTB graft is characterized by the presence of threads along at least a portion of the exterior surface of one or both bone blocks. In another embodiment, a self fixing assembled bone-tendon-bone implant comprises a removable tendon tensioner which imparts a predetermined tension on the tendon of the BTB graft.
