Abstract
According to an aspect, a preoperative planning method for a high-tibial knee osteotomy procedure is provided. The method includes: a) constructing a 3D model of a patient's bones; b) analyzing the 3D model to select a desired correction angle to apply to the patient's tibia bone to adjust a mechanical axis thereof; c) determining surgical steps required to apply the desired correction angle to the patient's tibia bone; d) designing a patient-specific guide to guide generic surgical tools in performing the surgical steps, the patient-specific guide being designed to conform to the anatomy of the patient's bones based on the 3D model; and e) manufacturing the patient-specific guide designed in step d). A corresponding kit, system and computer readable medium for performing the method are also provided.
