Anatomic Anterior Cruciate Ligament Reconstruction: The Use of the Anterior Horn of the Lateral Meniscus as a Guide to Tibial Tunnel Placement.

Anatomic anterior cruciate ligament reconstruction has been shown to reduce the risk of graft failure and to improve patient-related clinical outcomes. The posterior border of the anterior horn of the lateral meniscus is a useful marker for anatomic tibial tunnel placement. Assessment of a preoperative magnetic resonance imaging scan can allow surgical planning of tibial tunnel placement to allow for anatomic, patient-specific tibial tunnel placement during anatomic anterior cruciate ligament reconstruction. We present this technique to show how to use the posterior border of the anterior horn of the lateral meniscus clinically.
