INTRODUCTION
Knee kinematics after Total Knee Replacement (TKR) are
shown to be affected by, among other things, the design of the
prosthesis and the surgical placement of prosthetic
components. Based on the ligament-strain energy-
minimization principle, a mathematical model of a knee was
constructed for studying the passive kinematics of condylar-
type total knee prosthesis. The model relied on knowledge of
