Advances and Prospects in Tissue-Engineered Meniscal Scaffolds for Meniscus Regeneration

Figure 3

Schematic diagram of the meniscus force-bearing mechanism. Meniscal configuration adapts well to the corresponding shape of the femoral condyles and the tibial plateau in the knee joint. The axial load force () perpendicular to the meniscus surface and horizontal force () are created by compressing the femur (). rebounds due to the tibial upgrade force (), whereas the leads to meniscal extrusion radially, which is countered by the pulling force from the anterior and posterior insertional ligaments. Consequently, tensile hoop stress is created along the circumferential directions during axial compression.
