Abstract
The current study proposed analyzing the free-rolling motion between the metal femoral part and the tibial polyethylene intermediate element UHMWPE. The effect of movements is evaluated by the moment of friction and the coefficient of rolling friction. The average coefficient of rolling friction depends on contact pressure distribution. A rapid decrease is observed for large values of the coefficient of friction at maximum angular velocities. The coefficient of friction on the free-rolling of the femoral component on the flat polyethylene support can be determined when the total number of oscillations (n=NOSC)is known from experiments. The frictional losses between the femoral metal component and the UHMWPE polyethylene tibial intermediate are determined. The loading device of the friction moment and the friction losses are observed by adapting the total knee prosthesis. In experimental part used inertial measurement connected to an integrated system using a sensor that records and displays the angle of rotation and the time until the moment of stopping (record oscillations). Oscillations are made by the femoral component on the flat polyethylene support when an imbalance is achieved compared to the initial state. The experiment was repeated ten times under identical conditions. The coefficient of statistical variation, defined as the ratio between the mean square deviation and the arithmetic mean, is 3.2%.
