Claim 0:
1. A surgical registration tool configured for use in a surgical registration on a bone comprising a femur having a shaft portion and a femoral condyle, the femoral condyle including a distal portion, a posterior portion, a medial portion, and a lateral portion, the surgical registration tool comprising:
a bone engagement structure being a single-piece construction and non-patient-specific, the bone engagement structure comprising a distal abutment structure configured to contact the distal portion of the femoral condyle, at least one posterior abutment structure configured to contact the posterior portion of the femoral condyle, a side abutment structure, and an anterior abutment structure, the distal abutment structure comprising a distal planar surface, the at least one posterior abutment structure comprising at least one planar surface extending distally from the distal planar surface and positioned perpendicular to the distal planar surface, the side abutment structure comprising a planar surface extending distally from the distal planar surface and positioned perpendicular to the distal planar surface and the at least one planar surface, the planar surface of the side abutment structure configured to contact at least one of the medial or lateral portion of the femoral condyle, the anterior abutment structure extending distally from the distal planar surface and terminating at a distal tip configured to contact the shaft portion of the femur; and
a tracker array operably coupled to the bone engagement structure, the tracker array configured to be tracked by a navigation system.
