“…Essentially, the tissues of the musculoskeletal system are composed of fibers, proteins, water, and electrolytes, which are ingeniously combined to give each tissue a specific mechanical function. 17,18 Proteoglycans, associated with osmotic and swelling effects, can affect the viscoelasticity and other characteristics of tissues after combining with water. 19 Collagen fibers give the tissue a certain amount of tensile strength.…”

The knee is the most complex joint in the human body, including bony structures like the femur, tibia, fibula, and patella, and soft tissues like menisci, ligaments, muscles, and tendons. Complex anatomical structures of the knee joint make it difficult to conduct precise biomechanical research and explore the mechanism of movement and injury. The finite element model (FEM), as an important engineering analysis technique, has been widely used in many fields of bioengineering research. The FEM has advantages in the biomechanical analysis of objects with complex structures. Researchers can use this technology to construct a human knee joint model and perform biomechanical analysis on it. At the same time, finite element analysis can effectively evaluate variables such as stress, strain, displacement, and rotation, helping to predict injury mechanisms and optimize surgical techniques, which make up for the shortcomings of traditional biomechanics experimental research. However, few papers introduce what material properties should be selected for each anatomic structure of knee FEM to meet different research purposes. Based on previous finite element studies of the knee joint, this paper summarizes various modeling strategies and applications, serving as a reference for constructing knee joint models and research design.

“…For the exudation of the lubricant from the porous matrix, the porous self-lubricating surface has a good bearing capacity, dynamic adaptability, and an ultralow friction coefficient during the friction process. [1][2][3] These excellent properties make the porous material widely used in advanced lubrication technologies, such as superlubrication films, articular cartilage, and biomimetic self-lubricating materials. [4,5] Generally speaking, the elastic modulus of the porous material is relatively small.…”

Percolation and Supply Behavior of Lubricant on Porous Self‐Lubricating Material

et al. 2023

This article aims to investigate the percolation and supply behavior of lubricant on the porous self-lubricating material. The numerical model is established to describe the infiltration-exudation response in the deformed porous material. It is found that the lubricant stored in the pores is forced to flow when the loaded porous matrix deforms. The flow drives the seepage stratification in the porous body and forms an interlayer flow zone. The fluid pressure gradient in the normal direction is the internal factor of the seepage stratification. The interlayer flow zone first appears in the middle of the vertical direction of the porous matrix. With the increase of loading time, the interlayer flow zone gradually moves from the middle to the bottom of the porous matrix, which means that the quantity of the lubricant stored in the porous surface decreases. In the whole process of the seepage response, the lubricant flows out from the inlet and continuously supplies lubricant to the contact area. Delaying the downward movement of the interlayer flow zone can ensure the continuous exudation of the lubricant, which is beneficial to maintain excellent lubrication characteristics.
