Femoral Footprint Visualization Using a Transtibial Portal in Anterior Cruciate Ligament Reconstruction.

Abstract

In traditional endoscopic anterior cruciate ligament (ACL) reconstruction, inadequate visualization of the femoral footprint through a lateral portal frequently causes surgical errors. Although various portal locations have been reported, no study has identified ideal locations for specific portals in relation to ACL reconstruction. This article presents the new transtibial portal technique (ie, the use of an existing tibial tunnel). This technique provides excellent direct visualization of the femoral ACL footprint without the need to create additional portals. It allows dynamic visualization of the relationship of the future graft with posterior cruciate ligament and bone structures. [<i>Orthopedics</i>. 2021;44(5):e691-e693.].
