Anatomical single-bundle anterior cruciate ligament reconstruction with a transtibial technique.

To position a single-bundle anterior cruciate ligament reconstruction anatomically on the femoral side while still using a transtibial technique, we recommend performing a posterolateral notchplasty, inserting the tibial aimer through an accessory inferomedial portal, using a more proximal tibial starting point, removing bone from the posterolateral corner of the tibial tunnel, and externally rotating the over-the-top guide.
