Three Options for Femoral Tunnel Trajectories^a

Tunnel Option	Considerations
A: Vertical transphyseal
Advantage	Minimizes physeal volume affected
Disadvantage	Less-than-ideal coverage of ACL footprint
B: Oblique transphyseal
Advantage	Anatomic graft position covering the ACL footprint
Disadvantage	Greater volume of physis negatively affected
C: Horizontal all epiphyseal
Advantage	Appropriate placement at ACL footprint; no drilling through the physis
Disadvantage	Requires precise tunnel placement to reduce the risk for physeal damage
