摘要： 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.
