摘要：
The present invention has multiple aspects relating to a bone-tendon-bone graft and components thereof. Embodiments of the present invention comprise an intermediate bone block that is used to adjustably secure soft tissue (e.g., tendon) in a patient. Preferred intermediate bone blocks comprise at least one machined segment of cortical bone, cancellous bone or both. Embodiments of intermediate bone blocks of the present invention are used singly or in combination with one or more bone blocks to form a bone block assembly for securing soft tissue. The present invention further relates to an assembled bone-tendon-bone graft suitable for implantation in humans comprising the intermediate bone block and a length of soft tissue. In a preferred embodiment, a bone-tendon-bone graft comprises a length of soft tissue (e.g., tendon) extending from a first assembled bone block to a second bone block and then doubles back to said first assembled bone block. Depending upon the embodiment, the second bone block fixedly or slideably attaches to the length of soft tissue and facilitates it doubling back to the first assembled bone block.
