Abstract: A method includes obtaining rotational data and translational data for a joint, the rotational and translational data being indicative of rotational and translational movement of the joint during rotational and translational joint testing, respectively, the rotational and translational joint testing being implemented by a robotic testing apparatus applied to the joint. A quantity indicative of joint play of the joint is computed. The quantity is computed via a function of the rotational data and the translational data. The method includes determining whether the computed quantity exceeds a joint play threshold and, if the computed quantity exceeds the joint play threshold, comparing the rotational data and the translational data with preset rotational data and preset translational data for the rotational and translation joint testing, respectively.

Abstract: A method includes disposing an object relative to a first body, positioning a second body within a field of view of an imaging system such that the object is within the field of view and the first body is outside the field of view, and capturing, by the imaging system, data indicative of the object and the second body.

Abstract: A knee examination method includes situating a patient on a patient support adjacent a robotic knee testing apparatus, the apparatus having a motion tracking system. The robotic knee testing apparatus is set up including defining a world coordinate system based on a fixed location of a transmitter of the motion tracking system. The patient is set up including determining one or more local coordinate systems each based on setting up the patient and on one or more robot based points. The robotic knee testing apparatus is operable to manipulate a leg of the patient.

Abstract: A method comprises obtaining rotational data and translational data for a joint. The rotational and translational data is indicative of rotational and translational movement of the joint during rotational and translational joint testing, respectively. The rotational and translational joint testing is implemented by a robotic testing apparatus. Respective zero torque points are determined for the rotational and translational movement based on the rotational data and the translational data. The respective zero torque points are combined for the rotational and translational movement to determine an equilibrium position for the joint. A biomechanical characteristic of the joint is ascertained based on an analysis of the equilibrium position.

Abstract: A joint manipulation and evaluation apparatus has a mechanism configured to manipulate a first bone of a joint relative to a second bone of the joint. The apparatus has a joint stabilizer arranged to engage the joint and hold the second bone in place as the first bone is manipulated. A sensor is coupled to the joint stabilizer and is configured and arranged to detect residual movement of a clamped portion of the joint relative to the joint stabilizer as the first bone is manipulated.

Abstract: A method includes obtaining test data for a joint, the test data being indicative of motion of the joint during joint testing implemented by a robotic testing apparatus applied to the joint to impart force oriented in a first degree of freedom for the joint, generating first data indicative of movement of the joint in the first degree of freedom based on the test data, generating second data indicative of concomitant movement of the joint in a second degree of freedom for the joint based on the test data, the concomitant movement arising from the imparted force, and determining a condition of the joint based on an analysis of the first data and the second data.

Abstract: A method includes obtaining test data during a plurality of joint tests, the test data being indicative of respective motion during each test, each test being implemented by a robotic testing apparatus that applies, during each test, a respective force oriented in a respective plane. Respective primary data indicative of respective movement in a respective degree of freedom disposed within the respective plane for each test is generated based on the test data. Secondary data indicative of concomitant movement during a first test of the plurality of tests is generated based on the test data, the concomitant movement being in a secondary degree of freedom other than the respective degree of freedom disposed within the respective plane for the first test, the concomitant movement arising from the respective applied force. A joint condition is determined based on the primary data for each test and the secondary data.
