Abstract: 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.

Abstract: 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.

Abstract: A tibial prosthesis comprises a medial base portion configured to engage a medial surface of a tibia and a lateral base portion configured to engage a lateral surface of the tibia. At least a portion of the medial and lateral base portions are separated by a passage interposed therebetween. The tibial prosthesis also comprises a bridge coupling the medial base portion and the lateral base portion, wherein at least a portion of the bridge is elevated above a portion of the passage between the medial base portion and the lateral base portion. The bridge may define an underlying area that receives at least a portion of a tibial eminence when the tibial prosthesis is engaged with the tibia, wherein the height of the bridge varies in a superior direction across the passage.

Abstract: A femoral prosthetic component comprises a pair of condyles having an intercondylar notch interposed substantially therebetween. Each of the pair of condyles comprises an edge that borders the intercondylar notch. At least one of the pair of condyles comprises a condylar notch disposed within the respective edge of the at least one of the pair of condyles.

Abstract: An orthopedic prosthetic system comprises a base portion and an elongated guide member protruding from a bottom surface of the base portion. The elongated guide member extends from a posterior edge of the base portion toward an anterior edge of the base portion and comprises an overhang element and an undercut face. The prosthetic system further comprises an insert portion configured to slideably engage the base portion and the elongated guide member. The insert portion comprises an underhang element configured to engage at least a portion of an undercut area defined by the overhang element and undercut face of the elongated guide member.

Abstract: 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.
