Abstract
A method and apparatus for anterior cruciate ligament (ACL) reconstruction using sockets in bone created by retrograde cutting. A retrograde rotary cutter, inserted 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 retrograde drill pin, guided by a drill guide, is drilled through the tibia until it contacts the rotary cutter. Once the cutter is disengaged from the guide and securely engaged in the retrograde drill pin, the retrograde drill pin is retracted for retrograde cutting of a socket of desired depth in the tibia.
