Abstract

A computer-implemented method of planning knee replacement surgery, the method comprising:▪ Receiving input related to an anatomy of a patient, wherein the input comprises imaging data related to the femur, the tibia, the patella and optionally the hip, pelvis, the fibula, the ankle, and/or the bones in the foot;▪ Generating a three-dimensional (3D) model of the anatomy based on the input, wherein the 3D model comprises a patella model, a model of the femur, the tibia and optionally of the fibula, the pelvis, the hip, the ankle and the bones in the foot;▪ Characterizing a morphology of the patella, the femur, the tibia, and optionally the fibula, the hip, the pelvis, the ankle and the bones in the foot based on the 3D model;▪ Determining one or more implant-related or morphological parameters based on one or more of the 3D model and the morphology;▪ Performing one or more morphological and/or biomechanical simulations based on the one or more implant-related or morphological parameters, wherein the simulations include one or more poses of the patella-femoral and tibio-femoral joint through a range of motion thereof and optionally a range of motion of the hip and/or the ankle;▪ Optimizing a position, an orientation and optionally a size of the femur implant relative to the native femur and patella based on the one or more morphological and/or biomechanical simulations;▪ Optionally optimizing a position, an orientation and optionally a size of the tibia implant relative to the femur implant, femur implant position and patella based on the one or more morphological and / or biomechanical simulations; and▪ Outputting patient-specific planning information to one or more of an external computing device, visual display and a computer-readable storage device.
