测量了8对人膝关节半月板在生理相关载荷水平下的半月板组织对轴向、径向和周向压力的响应。加压为无限制单轴加压。应力-应变数据符合双参数指数模型。研究发现，轴向压力下的组织比径向和周向压力下的组织要坚硬得多。在对周向力和径向力的反应之间没有发现显著差异。
The response of meniscal tissue to axial, radial and circumferential compressive forces was measured at physiologically relevant levels of load in eight pairs of human knee joint menisci. Compression was unconfined and uniaxial. Stress-strain data were fitted to a two-parameter exponential model. The tissue was found to be significantly stiffer to axial compressive forces than to radial and circumferential forces. No significant difference was found between the responses to circumferential and radial forces.
