Publication number: 20230074652Abstract: Measured forces applied by a medical professional during a gap assessment can be measured. A plurality of force sensors is placed at a lateral ankle position, a medial ankle position, a lateral foot position, and/or a medial foot position, and each detects an applied force during an abduction-adduction examination. Further, a computing device receives, from each of the plurality of sensors during the abduction-adduction examination, data representing an applied force occurring during the abduction-adduction examination at respective ones of the lateral ankle position, the medial ankle position, the lateral foot position, and the medial foot position. The computing device calculates, using the received data, respective peak applied forces during the abduction-adduction examination in extension and flexion, and provides information representing a correlation of the respective peak applied forces with other information.Type: ApplicationFiled: February 5, 2021Publication date: March 9, 2023Inventors: Shady ELMASRY, Carl IMHAUSER, Peter SCULCO, Geoffrey WESTRICH, Cynthia KAHLENBERG

Patent number: 10789858Abstract: The present invention provides a method for creating a computer model of a patient specific joint for treatment planning. The method includes identifying a ligament of a joint of a patient under a load at a predefined position of the joint. The method further includes constructing, with the use of a computer, a computer model of the joint of the patient having: a first bone model, a second bone model, and a ligament model connecting the first and second bone models corresponding to the identified ligament, wherein the ligament model is constructed as at least one fiber based on a predefined slack length.Type: GrantFiled: February 4, 2019Date of Patent: September 29, 2020Assignee: Hospital for Special SurgeryInventors: Carl Imhauser, Kevin Schafer

Patent number: 10750979Abstract: An apparatus for determining 3D load displacement characteristics of an anatomical joint formed by a first body portion and a second body portion moveable with respect to the first body portion. The apparatus includes a first frame for receiving and securing the first body portion and a load displacement assembly. The load displacement assembly includes a first axis for alignment with a first anatomical plane of the joint, a second frame for receiving and securing the second body portion. The second frame is movable relative to the first frame. The load displacement assembly also includes a first counterweight configured to balance the weight of the second frame, a force for applying a load to the second frame, and a displacement sensor for measuring displacement of the second frame relative to the first frame upon application of the force.Type: GrantFiled: January 12, 2017Date of Patent: August 25, 2020Assignee: HOSPITAL FOR SPECIAL SURGERYInventors: Carl Imhauser, Brendan Dugan, Jeffrey Kinsberg
