摘要：

The purpose of this article is to construct a real model of the knee joint to determine fluid's behavior inside it, based on the computed tomography (CT) scan images of a patient. The meniscus and cartilage are considered as porous media and are modeled as poroelastic materials. The main output is the velocity profile in the knee joint. Results show that the fluid content velocity is maximum through the lateral surfaces. Moreover, effect of aging is studied by varying the permeability of the meniscus. It is observed that the permeability has direct correlation with the fluid flow velocity inside the knee joint.
