Abstract
A patient-specific instrument is placed into a predetermined setting position with respect to a patient tissue. A navigation aid is associated in a predetermined origin position with respect to the patient tissue. The navigation aid is zeroed while in the predetermined origin position to record the location and orientation of the navigation aid relative to the patient tissue. An instantaneous position of the zeroed navigation aid is determined with respect to the patient tissue. Feedback is provided to a user on a physical motion needed to bring the instantaneous position of the navigation aid closer to a predetermined desired target position. An indication is made when the instantaneous position of the navigation aid is sufficiently similar to the predetermined desired target position.
