A Newer Technique of Extended Cortical Fixation to Salvage Intratunnel Blowout during Revision Anterior Cruciate Ligament Reconstruction – A Case Report

摘要

Posterior femur wall blowout and consequent loss of femoral graft fixation are commonly encountered distally at the aperture of the tunnel facing into the joint during anterior cruciate ligament (ACL) reconstruction. However, intratunnel blowout of femoral tunnel at its outer cortical opening during a revision ACL reconstruction is very rare. It compromises the mechanical strength of the cortical bone at the tunnel opening on lateral cortex, making it weaker for providing stability to endobutton. We report this very rare event of intratunnel blowout of femoral tunnel at its proximal opening on the lateral femoral cortex during a revision ACL reconstruction, where the patient was treated with a modification in the suspensory fixation technique using a suture disc.
