Although the independent drilling techniques using transportal portal or outside-in approaches in ACL reconstruction have some advantages over the trans-tibial technique in placing the anatomical femoral tunnel, these techniques may make an acute graft-bending angle at the femoral tunnel entry or result in a short femoral tunnel length. However, there have been no reports on whether an acute graft-bending angle of an independent drilling technique might result in poor graft healing or negatively affecting clinical outcomes. The purpose of this study was to compare femoral tunnel geometry including tunnel position, length, and graft bending angle between the transportal and the outside-in techniques in ACL reconstruction and discover whether such differences in tunnel geometry could influence graft healing or clinical outcomes.
