Patent number: 12213686Abstract: To address technical problems facing knee arthroplasty resection validation, the present subject matter provides a tracked knee arthroplasty instrument for objective measurement of resection depth. By performing a precise comparison between the location of the tracked knee arthroplasty instrument and a reference location, the knee arthroplasty instrument measures and validates each tibial and femoral resection. To address technical problems facing validation of joint laxity following knee arthroplasty, the tracked knee arthroplasty instrument is shaped to validate the flexion gap and extension gap. When the tracked knee arthroplasty instrument is inserted between the resected tibial plateau and femoral head, the instrument shape validates whether the desired flexion gap and extension gap have been achieved.Type: GrantFiled: December 16, 2021Date of Patent: February 4, 2025Assignee: Orthosoft ULCInventors: Emily Gogarty, Pierre Couture, Adam H.

Patent number: 12137952Abstract: A device used in conjunction with fixation hardware to provide a two-stage process to address the competing needs of immobilization and re-establishment of normal stress-strain trajectories in grafted bone. A method of determining a patient-specific stress/strain pattern that utilizes a model based on 3D CT data of the relevant structures and cross-sectional data of the three major chewing muscles. The forces on each of the chewing muscles are determined based on the model using predetermined bite forces such that a stiffness of cortical bone in the patient's mandible is determined. Based on the stiffness data, suitable implantation hardware can be designed for the patient by adjusting external topological and internal porous geometries that reduce the stiffness of biocompatible metals to thereby restore normal bite forces of the patient. A method of 3D printing nitinol to create a patient-specific device to facilitate the establishment of a normal stress-strain trajectory in grafted bone.Type: GrantFiled: January 18, 2023Date of Patent: November 12, 2024Assignees: OHIO STATE INNOVATION FOUNDATION, THE UNIVERSITY OF TOLEDOInventors: Howard David Dean, Mohammad H.
