摘要：
Knee arthroplasty instrument systems directly reference and align with the anterior distal with the anterior distal femoral cortex, the mechanical axis of the leg, and Whiteside's line. The anterior femoral resection is aligned in the same plane as the anterior distal femoral cortex. The center of the femoral head, the medial/lateral center of the distal femur, the medial/lateral center of the proximal tibia, and the second toe, medial/lateral center of the ankle, or anterior tibial spine are all aligned to the mechanical axis of the leg while the leg is in full extension and the knee joint is distracted. Whiteside's line is referenced while the distal femur is intact, before any distal femoral resection, and the anterior and posterior femoral resections and chamfer cuts are aligned to this reference using a jig. Methods of using the instrument systems are disclosed.
