Abstract: Systems and methods may be used to perform robot-aided surgery. A system may include a display device and a computing device including a memory device with instructions. The instructions can cause the system to access surgical data, calculate medial and lateral gap data, calculate a recommended component set, and generate a graphical user interface. Accessing surgical data can include accessing soft tissue data indicative of at least tension in soft tissues surrounding a surgical location. The graphical user interface can include an interactive trapezoidal graphic overlaid onto a graphical representation of a distal femur and a proximal tibia. The interactive trapezoidal graphic can include a graphical representation of a medial total gap, a lateral total gap, and a recommended spacer size. The interactive trapezoidal graphic can update in response to adjustments in implant parameters to assist in surgical planning.

Abstract: An impactor mechanism for virtual or telepresence surgery comprises a base. An impactor shaft has a first end and a second end, a handle portion being provided at the second end. A rotational joint(s) is between the first end of the impactor shaft and the base, the joint providing two or more rotational degrees of freedom to the impactor shaft. Sensors are in the impactor mechanism for measuring an orientation of the impactor shaft relative to the base, and for measuring at least an impact force on the impactor shaft, for use in virtual surgery.

Abstract: A patient-specific cutting assembly comprises a model file including geometrical data of a bone of the patient, of an intramedullary canal of the bone, and a planned orientation of a cutting block. A fixing rod is adapted to be longitudinally inserted in and extending partially from the intramedullary canal. A patient-specific cutting block is connectable to the fixing rod. The patient-specific cutting block includes a structure having a patient specific geometry corresponding to the model file of the patient, the structure configured to be connected to a portion of the fixing rod projecting from the bone in a unique coupling orientation. A cutting guide is connected to the structure, the cutting guide being in the planned orientation when the structure is connected to the portion of the fixing rod projecting from the bone.
