Abstract
A system for anterior cruciate ligament (ACL) reconstruction using holes in bone created by retrograde cutting. A rotary cutter, mounted onto an insertion post of a tibial guide, is inserted through an anteromedial portal and the rotary cutter placed on the anatomical origin of an ACL tibial insertion. A drill pin is drilled through the tibia and advanced until it contacts and engages a cannulation in the rotary cutter on the guide. Further rotation of the drill pin disengages the rotary cutter from the guide. The retrograde drill pin is then retracted and simultaneously rotated for retrograde cutting of a socket or tunnel of desired depth in the tibia. A similar system is provided to form a socket or tunnel in the femur except that a femur guide is used in place of the tibial guide.
