摘要

小牛血清在ISO标准中被定义为体外膝关节磨损模拟研究的测试液。然而,蛋白质降解通常发生在体外磨损模拟过程中。目前的研究应该表明,是否增加的载荷改变了测试流体的流变特性,从而可能导致良好的摩擦学行为和减少磨损。在一项位移控制的膝关节磨损模拟研究中,模拟了三种不同的负荷水平。在0.5 × 106次循环模拟后,确定了重量磨损率,进行了压力测量,并分析了测试流体的动态粘度。与中等和高负荷水平相比,最低负荷水平导致最低的磨损率,最低的接触压力和接触面积。虽然高负荷水平导致最高的接触压力和接触面积,但磨损率与中等负荷水平相当。流变学测试表明,高负荷水平下的动态粘度最高,中、低负荷状态下的动态粘度没有差异。为了进行真实的磨损模拟研究,有必要再现剪切力与磨损之间的体内相互关系。

In Vitro Wear Behavior of Knee Implants at Different Load Levels: The Impact of the Test Fluid
Calf serum is defined as a test fluid for in vitro knee wear simulation studies in the ISO standard. However, protein degradation typically occurs during in vitro wear simulation. The current study should indicate whether increased loads change the rheological properties of the test fluid and may, therefore, lead to favorable tribological behavior and reduced wear. Three different load levels were simulated in a displacement-controlled knee wear simulation study. The gravimetric wear rates were determined, pressure measurements were performed, and the dynamic viscosity of the test fluids were analyzed after the simulation of 0.5 × 106 cycles. The lowest load level led to the lowest wear rate, and the lowest contact pressure and contact area, compared to the medium and high-load level. Although, the high-load level led to the highest contact pressure and contact area, the wear rates were comparable to the medium-load level. The rheological measurements revealed the highest dynamic viscosity for the high-load level and no differences could be found between the medium and low loading condition. To perform realistic wear simulation studies, the reproduction of the in vivo interrelationships between the shear forces and wear are necessary.
