Editorial Commentary: Posterior Cruciate Ligament Femoral Techniques: The “Critical Corner” Is Just Not as Exciting as the “Killer Turn”

The “killer turn” between the graft and tibial tunnel in posterior cruciate ligament reconstruction has always been of technical and clinical importance. The “critical corner” of the graft and femoral tunnel has garnered less interest. Technical advances in arthroscopic instrumentation have allowed a move from inside-out to outside-in techniques, which can assist with tunnel placement and drilling. While these techniques do not impact the “killer turn,” they have been demonstrated to decrease the acuity of the “critical corner,” but there remains no evidence of impact on graft rupture or clinical outcomes.
