Patent number: 10226301Abstract: Alignment precision technology, in which a system accesses image data of a bone to which a reference marker array is fixed. The system generates a three-dimensional representation of the bone and the reference markers, defines a coordinate system for the three-dimensional representation, and determines locations of the reference markers relative to the coordinate system. The system accesses intra-operative image data that includes the bone and a mobile marker array that is attached to an instrument used in a surgical procedure. The system co-registers the intra-operative image data with the three-dimensional representation by matching the reference markers included in the intra-operative image data to the locations of the reference markers. The system determines locations of the mobile markers in the co-registered image and determines a three-dimensional spatial position and orientation of the instrument relative to the bone.Type: GrantFiled: August 23, 2018Date of Patent: March 12, 2019Assignee: Smith & Nephew, Inc.Inventors: Zachary Christopher Wilkinson, Ryan Lloyd Landon, Brian W. McKinnon

Patent number: 10201356Abstract: Methods and devices for performing knee arthroplasty including but not limited to bicruciate retaining knee arthroplasty are provided. Methods and devices for preparing a proximal tibia for a tibial implant are also provided. These methods and devices, in at least some embodiments and uses, facilitate decreasing the complexity of knee arthroplasty procedures such as bicruciate retaining procedures while maintaining, if not improving on, the safety, accuracy and/or effectiveness of such procedures.Type: GrantFiled: October 26, 2012Date of Patent: February 12, 2019Assignee: Smith & Nephew, Inc.Inventor: Zachary Christopher Wilkinson

Publication number: 20180271666Abstract: Certain embodiments generally provide an improved tibial base member comprising keel portions that allow one or both cruciate ligaments to be preserved. Other embodiments provide improved lateral and/or medial inserts having a mesial lip that helps relieve and/or prevent impingement between the femoral component and the tibial eminence. Other embodiments provide improved femoral components having various chamfers to provide additional clearance with respect to the tibial eminence and posterior cruciate ligament without decreasing bone coverage.Type: ApplicationFiled: May 25, 2018Publication date: September 27, 2018Applicant: Smith & Nephew, Inc.Inventors: Nathaniel Milton Lenz, Richard Michael Smith, Zachary Christopher Wilkinson, Brian William McKinnon, Abraham Biglari Salehi, Jonathan Kirk Nielsen, Michael D.
