ALONSO-POLO, MB; DE BORJA-SOBRON, F; MORA, F  and  VAQUERO, J. Intra-articular migration of a tibial bone block after an anterior cruciate ligament reconstruction using a bone-tendon-bone graft. Acta ortop. mex [online]. 2017, vol.31, n.6, pp.304-307. ISSN 2306-4102.

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.

Keywords : Divergence; tunnel; screw; anterior cruciate ligament.
