To aid an orthopedic surgeon in performing total knee replacement surgery, a computer-aided-design (CAD)-based graphic system is proposed for preoperative planning. This system consists of two parts. The first part reads the computed tomography (CT) scan data for the patient's leg and performs image analysis on the graphics computer. To interact with the surgeon's examination, CT images are manipulable on a high-resolution monitor. The output of this image analysis will be the extracted wire-frame data of the patient's leg bones and certain pins inserted previously into the femur and tibia for surgery. These data will be the input of the second part of the system, a 3-D graphic training system that emulates the procedures of total knee arthroplasty. This system will allow a surgeon to simulate the bone alignment, cutting, and implant placement.>
