Abstract: 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.

Abstract: A drill guide clamp for attachment to a bone may include a worm screw, a sliding rack moveably connected to the worm screw, and at least two circular integrated drill tubes that extend through the drill guide clamp. Each drill tube may be sized to allow at least one screw or pin to fix the drill guide clamp to the bone. The drill tubes may be positioned to ensure that the pins or screws that fix the drill guide clamp to the bone are parallel. The sliding rack may include engagement interfaces that are moveable between an engagement and non-engagement position with the pins or screws via movement of the sliding rack.

Abstract: Systems and methods for bone surface geometry generation include a computing device. The computing device projects first geometry data indicative of a first bone-contacting surface of a first bone of a patient to a coordinate space of a second bone of the patient to generate projected geometry. The second bone includes a second bone-contacting surface that interfaces with the first bone-contacting surface. The computing device also maps the projected geometry to a plurality of poses in a range of motion of the first bone relative to the second bone using position data indicative of relative positions of the first bone and the second bone at the plurality of poses in the range of motion. The computing device further selects intersecting geometry from the mapped, projected geometry to generate second geometry data indicative of the second bone-contacting surface.
