Anatomic Double-Bundle Transtibial Anterior Cruciate Ligament Reconstruction With Ligament Advanced Reinforcement System

It has been reported that anterior cruciate ligament reconstruction (ACLR) with the Ligament Advanced Reinforcement System (LARS) could obtain similar clinical outcomes to ACLR with autograft. However, in most related reports, single-bundle ACLR was performed. Given that double-bundle ACLR is more favorable than single-bundle ACLR biomechanically, it is reasonable to try double-bundle ACLR with the LARS clinically. Thus, we introduce an anatomic double-bundle transtibial ACLR technique with the LARS, in which the most critical step is to create a shallow tibial tunnel for the anteromedial bundle to further create the corresponding femoral tunnel in a transtibial manner, as well as to fix both bundles in full extension of the knee.
