ISO 14243-3:2014描述了一种试验方法，该方法规定了关节部件之间的弯曲/伸展相对角运动、施加力的模式、试验的速度和持续时间、样品配置和试验环境，用于在具有轴向载荷控制、弯曲/伸展角运动控制、，AP位移控制和胫骨旋转控制。 ISO 14243-3:2014本部分的运动学可能不适用于具有高度约束的膝盖设计，这可能会在试验的早期阶段损坏不代表临床服务的关节部件。

ISO 14243-3:2014 describes a test method that specifies flexion/extension relative angular movement between articulating components, the pattern of the applied force, speed and duration of testing, sample configuration and test environment to be used for the wear testing of total knee-joint prostheses in wear-testing machines having axial load control, flexion/extension angular motion control, AP displacement control and tibial rotation control. The kinematics of this part of ISO 14243-3:2014 may not be applicable to knee designs with a high degree of constraint, which could result in damage to the articulating components in the early stages of the test that would not be representative of clinical service.
