Abstract

An orthopedic apparatus includes an alignment guide attachable to one of a femoral joint surface of a femur of a patient. The alignment guide has a patient-specific three-dimensional engagement surface, and at least one guiding portion defining a guiding passage. The engagement surface anatomically matches a corresponding portion of the femoral joint surface.
