研究了关节软骨孔隙度对正常人髋关节润滑的影响。关节软骨的孔隙弹性方程和修改后的雷诺方程的滑液润滑剂已经成功地解决了squeezefilm运动和在正常人髋关节的条件下经历的。已经表明，关节软骨的多孔性耗尽润滑剂膜厚度，而不是增加润滑剂膜厚度，特别是当润滑剂膜厚度变小时。此外，它已被证明，关节软骨可以被视为一个单相不可压缩的弹性材料在润滑建模在生理行走条件下。
The effect of porosity of articular cartilage on the lubrication of a normal human hip joint has been studied. The poroelasticity equation of articular cartilage and the modified Reynolds equation for the synovial fluid lubricant have been successfully solved under squeezefilm motion and for the conditions experienced in a normal human hip joint. It has been shown that porosity of the articular cartilage depletes the lubricant film thickness, rather than increasing it, particularly when the lubricant film thickness becomes small. Furthermore, it has been shown that articular cartilage can be treated as a single-phase incompressible elastic material in the lubrication modelling under physiological walking conditions.
