A mathematical model for studying the passive kinematics of condylar- type total knee prostheses can be useful in planning and performing total joint re- placement. If the insertion location and neutral length of knee ligaments is known, the passive kinematics of the knee can be calculated by minimizing the strain en- ergy stored in the ligaments in any angular configuration of the knee. The model considered here takes into consideration the geometry of the prosthe- sis, patient-specific information, and operation-specific placement of the prosthe- sis. Based on an energy-minimization principle, this model can be used to study the kinematics of the knee joint of a patient after total joint replacement. The ef- fect of various articular geometries, alternative surgical placements of prosthetic devices, and intraoperative ligamentous release can be simulated. The model may be useful in preoperative planning, intraoperative guidance, and the design of new prosthetic joints.
