Advantages: |
Fluoroscopic images and radiation exposure is not necessary |
Easier identification of the PCL anatomic tibial footprint |
Accurate tibial stump preparation may allow for an easier graft passage avoiding the “killer turn” |
Direct guide-pin protection with the aid of a curette introduced from the “working” portal |
PM portals could be used to directly visualize the graft passage |
No need for additional 70° arthroscope |
Disadvantages: |
Increased theoretical risk of saphenous vein and sartorial branch of the saphenous nerve damage when creating the second portal |
Need for a second posteromedial incision |
