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: A method of positioning posterior resection guides in a three-dimensional coordinate system using robotic arms to perform partial knee arthroplasties comprises connecting a first tracking device for a surgical tracking system of the robotic arm to a femur, connecting a second tracking device for the surgical tracking system of the robotic arm to a tibia, manually positioning the tibia relative to the femur to a desired orientation to perform a posterior resection, manually determining a position for the posterior resection guide to perform the posterior resection, digitizing a reference point for the posterior resection guide in the three-dimensional coordinate system for a location of a feature of the posterior resection guide, moving the posterior resection guide to the location in the three-dimensional coordinate system with the robotic arm, and resecting a posterior portion of a condyle of the femur using the posterior resection guide to guide a cutting instrument.

Abstract: To address technical problems facing knee arthroplasty resection validation, the present subject matter provides a tracked knee arthroplasty instrument for objective measurement of resection depth. By performing a precise comparison between the location of the tracked knee arthroplasty instrument and a reference location, the knee arthroplasty instrument measures and validates each tibial and femoral resection. To address technical problems facing validation of joint laxity following knee arthroplasty, the tracked knee arthroplasty instrument is shaped to validate the flexion gap and extension gap. When the tracked knee arthroplasty instrument is inserted between the resected tibial plateau and femoral head, the instrument shape validates whether the desired flexion gap and extension gap have been achieved.

Abstract: Systems and methods may be used to perform robot-aided surgery. A system may include a robotic controller to monitor a position and orientation of an end effector coupled to an end of a robotic arm. The robotic controller may apply a force to a bone using the end effector, such as via a soft tissue balancing component. The robotic controller may determine soft tissue balance using information from a tracking system, such as a position of a first tracker affixed to the bone. The soft tissue balance may be output, such as to a display device.
