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.

Abstract: Disclosed herein is an improved Bone Tendon Bone graft for use in orthopedic surgical procedures. Specifically exemplified herein is a Bone Tendon Bone graft comprising one or more bone blocks having a groove cut into the surface thereof, wherein said groove is sufficient to accommodate a fixation screw. Also disclosed is a porcine bone tendon bone graft for use in orthopedic procedures. Also disclosed are multiple embodiments of assembled bone tendon bone blocks for use in orthopedic surgeries. Additionally, a method of harvesting grafts that has improved efficiency, increases the quantity of extracted tissue and minimizes time required by surgeon for implantation is disclosed.

Abstract: The present technology is related to the field of sterilization and decellularization of allografts or xenografts, specifically to processes that achieve effective removal of the cells contained within a vascular tissue matrix and an effective reduction in potential harmful organisms to create grafts suitable for human implantation. In some embodiments, vascular grafts, vascular tissue and/or blood vessels are contacted with cleaning solution under conditions suitable conditions to reduce immune reaction in patients. More specifically, the present technology is directed to sterilization and decellularization of vascular grafts.
Abstract: The present invention is directed to the field of implants that include soft tissue. More particularly, the present invention is directed to processes for treating implants that include soft tissues such as tendons and ligaments, and to implants produced by such processes. The present invention is also directed to processes and apparatus for improved processing of implants that include soft tissue, by applying kinematic restraint, preferably tension, to the implant or specific portions of the implants during the treatment, and to implants produced by such processes and apparatus. The present techniques yield soft tissue implants having superior structural, mechanical, and/or biochemical integrity.

Abstract: Disclosed herein is processed dermis graft for use in orthopedic surgical procedures. Specifically exemplified herein is a processed dermis graft comprising one or more bone blocks having a groove cut into the surface thereof, wherein said groove is sufficient to accommodate a fixation screw. Also disclosed is a method of processing dermis that results in a dermis derived implant suitable to replace a tendon or ligament in a recipient in need thereof. Other compositions and applications of a dermis derived implant, and methods of manufacture and use, are disclosed.
