Patent number: 11576689Abstract: A method of preparing a knee joint for a prosthesis in a patient includes mating a patient-specific three-dimensional curved inner surface of a femoral alignment guide onto a corresponding three-dimensional femoral joint surface of the patient. The patient-specific three-dimensional curved inner surface is preoperatively configured from medical scans of the knee joint of the patient.

Patent number: 11534313Abstract: A method for pre-operative orthopedic planning includes obtaining only a high-resolution knee-joint scan of a patient, determining hip rotation center and ankle rotation center from anthropometric data based on personal data of the patient, and determining a mechanical axis of the knee joint based on the anthropometric data. The method also includes preparing at least a two-dimensional image model of the knee joint using the knee-joint scan and the determined mechanical axis, and preparing a pre-operative surgical plan based on the image of the knee joint.Type: GrantFiled: October 11, 2019Date of Patent: December 27, 2022Assignee: Biomet Manufacturing, LLCInventors: Ryan John Schoenefeld, Brian Uthgenannt, Bryan Morrison, Robert Metzger

Patent number: 11443846Abstract: A method can include receiving, at a server, preoperative image data of a patient's bone, and accessing, at the server, a database of three-dimensional model data. A patient specific three-dimensional model of the patient's bone can be generated, at the server. A preoperative surgical plan can be generated at the server, which can include comparing aspects of the preoperative surgical plan with predetermined reliability criteria. An interactive user interface for use by a surgeon to review the preoperative surgical plan can be provided, from the server, to a user device. Approval of the preoperative surgical plan can be received, at the server, via the interactive user interface. Postoperative image data of the patient's bone can be received at the server. A postoperative outcome study report can be generated, at the server, and can include a comparison of the preoperative surgical plan with the postoperative image data.Type: GrantFiled: June 11, 2018Date of Patent: September 13, 2022Assignee: Biomet Manufacturing, LLCInventors: Ryan John Schoenefeld, Troy W.

Publication number: 20200054351Abstract: A patient-specific acetabular guide can be used for preparing an acetabulum of a patient to receive an acetabular implant. The acetabular guide includes a patient-specific engagement surface designed to be complementary and mateable with a corresponding surface of the patient's pelvic anatomy. The acetabular guide is designed during a pre-operative plan for the patient by a three-dimensional reconstruction of the anatomy of the patient using two-dimensional medical images. The patient-specific engagement surface has a first portion mateable with a portion of the acetabulum of the patient. The acetabular guide includes a guiding element that extends from the acetabular guide opposite to the first portion of engagement surface. The guiding element defines a bore designed to be oriented along an alignment axis for an acetabular implant when the acetabular guide is engaged to the acetabulum.Type: ApplicationFiled: October 23, 2019Publication date: February 20, 2020Inventors: Jason D. Meridew, Tyler D. Witt, Ryan John Schoenefeld, William Jason Slone, Adolph V. Lombardi, Jeffrey H. Nycz, Matthew D. Munsterman, Alexander P. Wolfe, Tamon Kabata, James Nairus, John C. Clohisy
