Abstract
A specialized obturator that has a curved configuration designed specifically for entry through the anterior joint and out the back of the knee in the ideal position for a posterior portal. The curved obturator is shaped to avoid intact knee ligaments and femoral condyles. The obturator is provided with an eyelet located at the tip and may be employed with a cannula similar to a PassPort™ Button cannula, but with one or more sutures placed through the “neck” behind the collar. A standard “inside-out” cannula may be used as well, but dimensioned for the specialized obturator.
