1. A knee examination method comprising the steps of:
situating a patient on a patient support adjacent a robotic knee testing apparatus;
setting up the robotic knee testing apparatus including defining a world coordinate system based on a fixed location of a transmitter of a motion tracking system;
further setting up the patient including determining one or more local coordinate systems each based on selected anatomical points on a leg of the patient and on one or more robot based points; and
operating the robotic knee testing apparatus to manipulate a leg of the patient.
