Patent number: 12226164Abstract: Systems and methods for planning and assisting orthopaedic surgical procedures include a computer system and a robotic surgical device. The computer system receives multiple surgeon preferences, including target values and boundary values for surgical parameters of the orthopaedic surgical procedure. A surgeon uses the computer system to perform bony registration and leg-alignment registration for anatomy of a patient. The computer system determines a surgical plan for the orthopaedic surgical procedure based on the surgeon preferences, the bony registration, and the leg-alignment registration. The surgical plan includes planned values associated with the surgical parameters that are within the boundary values of the surgeon preferences. Determining the surgical plan may include automatically adjusting tibial coronal alignment, femoral coronal alignment, femoral flexion, femoral rotation, distal femoral resection height, proximal tibial resection height, and/or distal femoral resection height.Type: GrantFiled: December 30, 2022Date of Patent: February 18, 2025Assignee: DEPUY IRELAND UNLIMITED COMPANYInventors: Adam Ryals, Daniel Girardeau-Montaut
