摘要：
A guide for drilling a tunnel in a knee joint having intercondylar roof and tibial eminence. The guide can comprise a guide assembly having a positioning member including an inferior end, and a guide arm extending from the positioning member including a trochlear tip； and a drill sleeve having a body attached to the inferior end, an aperture extending along a drilling axis, and a distal end having a patient-specific surface configured to engage an anterior surface of the tibia. A method of producing a tibial tunnel can comprise inserting a trochlear tip of a guide arm between the tibial eminence and the intercondylar roof, adjusting a position of a positioning member connected to the guide arm, engaging a patient-specific tip of a drill sleeve connected to the positioning member with a surface of a tibia, and inserting a drill bit through the drill sleeve to drill a tibial tunnel.
