  • Abstract The Knee joint is one of the most complicate joints of the human body. The centrode is one of the most efficient ways to describe the kinetic characteristics of human knee joints. There were many studies on the motion of the human knee joint using X-ray or camera to take photographs. This study develops a measuring stand consisting of three encoders are used to record the motion data of the human knee joint. The data averaging method and curve fitting technique have been used to minimize the measuring errors. The rigid body displacement method is used to calculate the fixed and moving centrode of the patients. The fixed centrode is located at thigh and the moving centrode is located at lower leg. When the moving centrode is rolling without slip on the fixed centrode, the trajectory of the certain appropriate point on the lower leg is equivalent to the coupler-point-curve of four-bar linkage. The coupler curves of the coupler-points are analyzed and a pairs of the coupler curves are choose as a pair of pin-in-slot kinematic pairs. The pin-in slot kinematics pairs are used to design the orthoses. The motion of the design of the orthoses is almost the same as the healthy knee of the patient.
