Abstract
A method for setting the internal-external rotational position of a prosthetic femoral component with respect to the tibial comprises: forming a cylindrical surface on the posterior femoral condyles. The cylindrical surface is formed about an axis extending in a proximal distal direction with respect to the femur. A template is placed on the distal femur which has a cylindrical guide surface for engaging the posterior femoral condyles. When placed against a planar resected surface of the distal femur the guide surfaces contact the cylindrically shaped posterior condyles. The template is rotated on the cylindrical guide surface as the knee joint is moved from flexion to extension until the template cylindrical guide surfaces are in a position with respect to the tibial condyle surfaces to properly balance the knee ligaments.
