A device for an orthopedic knee procedure. The device includes a tibial drill guide having a body portion and first and second posts extending from the body portion, the first post shorter in length than the second post. The device includes a patient-specific tibial alignment guide including a body with an inner anatomy-engaging surface shaped to closely conform and mate with a corresponding tibial joint surface. The first and second guiding receptacles define first and second inner channels sized and shaped to receive the first and second posts of the tibial drill guide. The first receptacle being shorter in length than the second receptacle, such that when the alignment guide is mounted on the tibial joint surface and the drill guide is mounted on the alignment guide, the first receptacle and the first post define a clearance gap between the tibia and the device for a patellar tendon.
