Apparatus for anterior cruciate ligament (ACL) reconstruction using rotary drill cutter to form retrograde sockets

摘要

An apparatus for anterior cruciate ligament (ACL) reconstruction using sockets in bone created by retrograde cutting. The system includes a rotary drill cutter (10), designed to be mounted on a tibial guide (72), and inserted through an anteromedial portal into a joint at the anatomical origin of an. ACL tibial insertion. The system also includes a drill pin (50), designed to be drilled through the tibia and advanced until it contacts and threadably engages the rotary drill cutter (10) mounted on the guide (72). The drill pin (50) is designed to disengage the rotary drill cutter (10) from the guide as the drill pin (50) engages the rotary drill cutter (10). The retrograde drill pin (50) has radially outward cutting teeth for retrograde cutting of a socket of desired depth in the tibia as the drill pin (50) is retracted and rotated.
