Abstract:
We report the case of a patient that presented an intra-articular protrusion of the tibial bone block after an arthroscopically-assisted ACL reconstruction using a bone-patellar tendon-bone graft. The divergence between the tunnel and the screw was thought to be the reason of the migration. There are several animal-model studies that evidence a relationship between the decreased fixation of the graft and the tunnel-screw divergence. To the best of our knowledge, this is the first report of this complication.

Bone Structure
Compact Bone
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
The Hyoid Bone
Spongy Bone
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...
