Table 1 Advantages and limitations

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
