Publication number: 20200275976Abstract: A method for optimizing a knee arthroplasty surgical procedure includes receiving pre-operative data comprising (i) anatomical measurements of the patient, (ii) soft tissue measurements of the patient's anatomy, and (iii) implant parameters identifying an implant to be used in the knee arthroplasty surgical procedure. An equation set is selected from a plurality of pre-generated equation sets based on the pre-operative data. During the knee arthroplasty surgical procedure, patient-specific kinetic and kinematic response values are generated and displayed using an optimization process. The optimization process includes collecting intraoperative data from one or more surgical tools of a computer-assisted surgical system, and using the intraoperative data and the pre-operative data to solve the equation set, thereby yielding the patient-specific kinetic and kinematic response values. A visualization is then provided of the patient-specific kinetic and kinematic response values on the displays.Type: ApplicationFiled: March 12, 2020Publication date: September 3, 2020Inventors: Brian W.

Publication number: 20200237385Abstract: Patient specific implant technology, in which an outline representation of a portion of an outer surface of a periphery of a bone volume is determined and the outline representation is used in operations related to implant matching. In addition, an instrument may be made to match a perimeter shape of a Patient Specific Knee Implant with features for locating holes in a distal femur such that posts or lugs in a femoral implant locate the femoral implant centered medial-laterally within an acceptable degree of precision to prevent overhang of either the side of the femoral implant over the perimeter of the distal femur bone resections. Further, a two-dimensional outline representation may be segmented into segments that correspond to resection cuts used in fitting an implant on a portion of a bone and operations related to implant matching may be performed based on the segments.Type: ApplicationFiled: March 23, 2020Publication date: July 30, 2020Inventors: James Bennett WIEBE, III, Ryan Lloyd LANDON, Brian William MCKINNON, Randy C.

Patent number: 10265081Abstract: A tibial cutting guide includes upper and lower portions having patient-matched surfaces. The upper portion defines resection slots for forming resections about the tibial eminence. The lower portion defines two pin slots for receiving alignment pins such that in use the position of the resection slots relative to the tibial eminence can be adjusted by sliding the cutting guide along the alignment pins placed in the tibia through the pin slots. The lower portion defines a resection slot for guiding a saw blade to form a horizontal plateau resection, and two pin holes for receiving fixation pins. A method includes positioning a patient-matched cutting guide on the proximal tibia; intra-operatively adjusting the position of the cutting guide in two degrees of freedom by sliding the cutting guide along fixation pins placed in the tibia; and resecting the tibia about the tibial eminence.Type: GrantFiled: August 9, 2013Date of Patent: April 23, 2019Assignee: SMITH & NEPHEW, INC.Inventors: Eric S.
