ABSTRACT:
A tibial tunnel guide which enables accurate tibial tunnel placement both inside and outside the knee for use in endoscopic ACL reconstruction. The guide utilizes a consistency between the PCL and the ACL anatomic structure to accurately locate the ideal position of the tibial tunnel. The guide includes an arc shaped outrigger with a slot along its length, a sighting device secured to the outrigger in the slot and adapted to receive a guide pin, and a grasping tool adjustably secured to the outrigger in the slot having a grasper at one end. The grasper is arranged to grasp the base of the PCL near the intercondylar floor from the anteromedial portal. The sighting device is fixed relative to the position of the crotch of the grasper and locates the guide pin at an ideal position for tibial tunnel placement.
