Femoral implant component

A method of preparing a bone to receive an implant component includes planning one or more surgical cuts configured to provide the bone with a curved intersection between two surfaces, applying a mechanical restraint to an arm holding a cutting tool based on the one or more surgical cuts, and performing, subject to the mechanical restraint and by articulating the arm, the one or more surgical cuts using the cutting tool.

Systems and methods for preparing a proximal tibia

A method includes obtaining a planned position of a first prosthetic component for implantation in a joint, obtaining positional data indicative of relative positions of bones of the joint, calculating, based on the positional data and the planned position of the first prosthetic component, a planned separation distance for the joint, facilitating adjustment of the planned position based on a desired separation distance by updating the planned separation distance in response to an adjusted planned position of the first prosthetic component, and guiding installation of the first prosthetic component in the joint in the adjusted planned position.

Tibial baseplate

A method of preparing a tibia to receive a tibial implant component includes performing a first set of cuts to prepare a floor interface surface on the tibia, wherein the floor interface surface includes a portion on each side of a tibial eminence extending above the floor interface surface on the tibia. The method further includes performing a second set of cuts to prepare a tibial eminence wall interface surface, wherein the wall interface surface extends substantially perpendicular to the floor interface surface between the floor interface surface and a top surface of the tibial eminence. The method further includes performing a third set of cuts to prepare a radiused intersection between the floor interface surface and the wall interface surface. The sets of cuts are performed subject to a cutting restraint guide. At least one set of cuts may be performed using a rotary cutter.

A method for guiding implantation of a first prosthetic component includes determining, using a virtual model of a joint including first and second bones, a planned orientation of the first prosthetic component in the joint, applying a valgus/varus moment to the joint at a plurality of flexion positions of the joint, and recording positional data indicative of relative positions of the first bone and the second bone at the plurality of flexion positions of the joint. The method also includes calculating estimated separation distances between the first prosthetic component and a second prosthetic component, adjusting the planned orientation of the first prosthetic component in the joint in response to an error between the estimated separation distances and one or more desired separation distances, and guiding implantation of the first prosthetic component on the first bone in accordance with the adjusted planned orientation of the first prosthetic component.

Tibial implant components

A method of planning a procedure to fasten an implant to a bone includes displaying a model of the bone and a model of the implant on a display device. The model implant is positioned on the model bone in a desired implant position. A first boundary volume of a first fastener configured to fasten the prosthesis to the bone is also displayed on the display device. The first boundary volume represents a range of possible positions that the first fastener may have with respect to the prosthesis when fastened to the bone. The boundary volume may be used to determine a desired size, shape, and/or positioning of the fastener with respect to the bone.

Implant placement planning

A method for repairing a bone of a patient may include superimposing a first virtual boundary on a virtual bone and superimposing a second virtual boundary on the virtual bone. The method may further include robotically modifying the bone of the patient with a planar tool along a first working boundary to create a first surface. The first working boundary may correspond to the first virtual boundary. The method may further include robotically modifying the bone of the patient with a rotary tool along a second working boundary to create a second surface. The second working boundary may correspond to the second virtual boundary.

Systems and methods for repairing bone with multiple tools

A computer-implemented method determines an orientation parameter value of a prosthetic component. The method includes receiving a first desired separation distance between a first prosthetic component and a second prosthetic component at a first flexion position of a flexion joint and estimating a first estimated separation distance between the first prosthetic component and the second prosthetic component at the first flexion position of the joint for at least one potential orientation of the first prosthetic component. The method also includes determining a first orientation parameter value of the first prosthetic component by comparing the first estimated separation distance to the first desired separation distance and outputting the first orientation parameter value via a user interface.

A computer-implemented method determines an orientation parameter value of a prosthetic component. The method includes receiving a first desired separation distance between a tibial prosthetic component and a femoral prosthetic component at a first flexion position of a knee joint and estimating a first estimated separation distance between the tibial prosthetic component and the femoral prosthetic component at the first flexion position of the knee joint for at least one potential orientation of the femoral prosthetic component. The method also includes determining a first orientation parameter value of the femoral prosthetic component by comparing the first estimated separation distance to the first desired separation distance and outputting the first orientation parameter value via a user interface.
