Patent number: 12127791Abstract: A computer-implemented method for updating a surgical plan for placement of a joint implant is disclosed. The surgical plan is obtained, including an implant model, an implant size, and an initial value for each of a plurality of placement parameters. At least one knee performance equation is selected from a library based on the surgical plan information, wherein each knee performance equation relates an output response associated with a post-operative influence to the plurality of placement parameters. Each output response is calculated across a range of values for each of a subset of the plurality of placement parameters. A graphical representation of the output response across each range is displayed, and input related to a selected value for each placement parameter of the subset is received. The surgical plan is updated based on the selected values. Devices and non-transitory computer readable media for carrying out the method are also disclosed.Type: GrantFiled: July 8, 2020Date of Patent: October 29, 2024Assignee: Smith & Nephew, Inc.Inventor: Daniel Farley
