Abstract
The present disclosure relates to a system for guiding an osteotomy procedure on a tibia and/or a femur pertaining to a patient's lower limb to correct a misalignment of said lower limb, wherein a tibial tracker is fixed to the tibia and a femoral tracker is fixed to the femur, said system comprising a control unit configured to be coupled to a localization system adapted to track a position and orientation of the tibial tracker and the femoral tracker, wherein the control unit is configured to: —receive at least one target alignment parameter of the lower limb provided by a user; —determine a position of a set of characteristic points on the tibia and/or the femur relative to the tibial tracker and/or the femoral tracker; —track the positions of said characteristic points relative to the tibial tracker and/or the femoral tracker based on localization data of the set of characteristic points during application of mechanical constraints by the user onto the patient's knee, said tracked positions forming a knee measurement data set; —based on the knee measurement data set, adjust a function defining a model of the patient's knee; —based on at least one output of said function and on at least one alignment parameter of the lower limb in the constrained position, determine at least one correction parameter of the osteotomy procedure to be applied to the lower limb to achieve the target alignment parameter.
