A knee examination method includes the steps of situating a patient on a patient support adjacent a robotic knee testing apparatus (50), setting up the robotic knee testing apparatus (50), further setting up the leg of the patient relative to the robotic knee testing apparatus (50), and, after the steps of setting up and further setting up, examining knee laxity of a knee of the patient. The step of examining includes operating the robotic knee testing apparatus (50) to manipulate a tibia positioning assembly.
