Flexible Instruments Outperform Rigid Instruments to Place Anatomic Anterior Cruciate Ligament Femoral Tunnels Without Hyperflexion
Steiner ME et al. – Transtibial drilling with rigid instruments did not produce anatomic femoral tunnels. Transtibial drilling with flexible pins produced anatomic tunnels, but the tunnels were close to the posterior femoral cortex. Anteromedial drilling without hyperflexion produced anatomic tunnels by use of rigid and flexible instruments, but with flexible instruments, the tunnels were longer and were farther from the posterior femoral cortex. Anteromedial drilling with flexible pins produced tunnels with good length and the best position.
