Abstract
A drill guide for drilling a tunnel in a tibia for anterior cruciate ligament replacement comprises a target hook having a point for engaging and determining the exit of the tunnel in the tibial plateau, and a handle carrying a drill guide sleeve holder and selectively variable means for adjusting and rigidly fixing the angular position of the holder relative to the plateau. The drill guide also comprises a drill sleeve longitudinally selectively adjustably received in the holder for axial movement toward and away from the point, the drill sleeve having a proximal end extending toward the point. The drill sleeve is cannulated to receive a guide wire with a sharpened point headed toward the point. Engagement means for holding the drill sleeve in a selected position is provided, thereby preselecting the desired tunnel length defined between the proximal end of said drill sleeve and the point.
