Anatomic Transtibial Tunnel Placement Using an Initial 6‐mm Drill Bit for Anterior Cruciate Ligament Reconstruction

Arthroscopy Techniques, EarlyView.
Abstract Precise anatomic tunnel placement is essential for restoring native knee biomechanics and minimizing graft failure in anterior cruciate ligament reconstruction. We describe a tibial tunnel drilling technique designed to enhance tunnel placement accuracy, reduce intra‐articular trauma, and preserve native tibial footprint remnants when ...
