Introduction

The premise of this article, and the scientific exhibit upon which
it is based, is that the morphologic shape of the distal aspect of the femur
and its relation to the tibia and the patella dictates the kinematics of the
knee. The morphologic and kinematic characteristics of the knee presented in
earlier
exhibits1,2
at the 2001 and 2003 Annual Meetings of the American Academy of Orthopaedic
Surgeons demonstrated the following relationships. The location and
orientation of the femoral sulcus is lateral to the midplane between the
femoral condyles and is oriented between the anatomic and mechanical axes of
the femur (Figs. 1-A and
1-B). The center of the femur
in cross section is offset, medial and anterior, to the center of the tibia,
and these offset cross sections are rotated relative to each other in the
pathologic knee (Fig. 2). A
single, fixed flexion-extension axis of . . . [Full Text of this Article]
