Anatomical Limitations of Transtibial Drilling in Anterior Cruciate Ligament Reconstruction

Abstract

If tunnels centered in the anterior cruciate ligament attachment sites are desired with the transtibial drilling technique, then a short tibial tunnel is necessary. A short tibial tunnel may compromise graft fixation and graft incorporation, or it may result in a tunnel length-graft length mismatch. An alternative drilling strategy might be employed.
