Transtibial technique |
Advantages |
Isometric graft placement |
Possibility of reaching native femoral insertion if tibial tunnel is made appropriately |
Ease of graft passage |
Familiarity and proven long-term outcomes |
Disadvantages |
Risk for non-anatomic graft placement |
Femoral tunnel placement constrained by tibial tunnel |
Tendency to create a vertical graft which can cause rotational instability and pivot shift if not appropriately positioned |
Short oblique tibial tunnel in an attempt to achieve anatomic ACL reconstruction |
Anteromedial technique |
Disadvantages |
Requires hyperflexion of the knee (requiring qualified assistants) |
Can result in a short femoral tunnel |
Can result in posterior wall blow-out due to tunnel angle |
