The meniscus, composed of fibrocartilage, is a very important part of the human knee joint that behaves like a buffer. Located in the middle of the femoral condyles and the tibial plateau, it is a necessary structure to maintain normal biomechanical properties of the knee. Whether walking or exercising, the meniscus plays a vital role to protect the articular surface of both the femoral condyles and the tibial plateau by absorbing the conveying shock from body weight. However, modern people often suffer from irreversible degeneration of joint tissue due to exercise-induced harm or aging. Therefore, understanding its dynamic characteristics will help to learn more about the actual state of motion and to avoid unnecessary injury. This study uses reverse engineering equipment, a 3D optical scanner, and a plastic teaching human body model to build the geometry of knee joint meniscus. Then, the finite element method (FEM) is employed to obtain the dynamic characteristics of the meniscus. The results show the natural frequencies, mode shapes, and fatigue life analysis of meniscus, with real human material parameters. The achieved results can be applied to do subsequent knee dynamic simulation analysis, to reduce the knee joint and lower external impacts, and to manufacture artificial meniscus through tissue engineering.

“…In a study by Camarda et al, a comparison of the cyclic stiffness and ultimate load in load-to-failure tests on posterior horns of humans aged 50-70 years and porcine samples was undertaken [35]. Specimens sutured with three simple stitches using #2 UHMWPE threads were subjected to 1000 cycles of loading ranging from 10 N to 30 N, followed by a load-tofailure test.…”

“…Consequently, the porcine model is a practical and economically feasible choice that finds extensive use in the biomechanical testing of meniscal repair and replacement techniques and allows for the reasonable translation of the results to clinical applications [31][32][33][34]. However, it is not proven that the entire set of biomechanical properties of the porcine meniscus matches those of the human meniscus [33][34][35], raising concerns about the use of this model as a human surrogate and underscoring the need to evaluate its applicability in relation to the specific parameters intended to be studied.…”

Meniscal root repair is not routinely recommended for patients over 75 years old, yet surrogate age-unrestricted human or porcine models are used for its evaluation. This study assesses the suitability of older human or porcine meniscus models for in vitro testing of the sutured meniscal horn. Three groups of menisci underwent a load-to-failure test with continuous monitoring of the traction force and deformation around the suture: human < 75 years, human ≥ 75 years, and porcine. Both surrogate models were compared to the younger group. The porcine group exhibited a 172.1%-higher traction force before tearing (p < 0.001) and a 174.1%-higher ultimate force (p < 0.001), without there being differences between the human groups. At tissue level, the older group had a 28.7%-lower cut-out stress (p = 0.012) and the porcine group had a 57.2%-higher stress (p < 0.001). Regarding elasticity at the sutured area, a 48.1%-greater deformation rate was observed in the older group (p < 0.001), without difference for the porcine group. In conclusion, neither the porcine nor the older human model demonstrated a clear advantage as a surrogate model for young human sutured meniscal horns. The older human meniscus is preferable for resistance at the specimen level, while the porcine model better represents deformation in the sutured zone.

“…The presence of biological tissues with a marked presence of hydrated collagen, as in meniscus tissue, makes, however, largely ineffective the elastic models of the material since a marked-time dependent behavior of the representative volume element is observed also in absence of fluid-filling material pores. 13,16,[27][28][29][30][31][32][33][34] As a consequence a mathematical formulation that can be used to represent this mechanical behavior is the linear theory of material hereditariness that is nowadays described by the so-called Fractional-Order hereditariness (FOH). In this setting the formalism of fractional-calculus, lately used in several biomechanical contexts 18,21,25,26 allows to replace the well-known constitutive equations of classical linear elasticity with their-fractional-order counterparts, involving, as additional parameters the derivation order β 0, 1 ½ .…”

“…The common base of aforementioned approaches is represented by the linear elastic behavior of the fibrous tissue representing the meniscus. However, it is well‐known as reported in relevant scientific literature that the stress in collagen tissue representing meniscus depends on past history of strain and not only on the actual value of the strain 13–17 . This effect is known as material hereditariness and it is usually represented by coupling linear elastic springs and linear viscous dashpot to represent the material behavior 11,18–22 …”

Biomechanics of biological fibrous tissues as the meniscus are strongly influenced by past histories of strains involving the so‐called material hereditariness. In this paper, a three‐axial model of linear hereditariness that makes use of fractional‐order calculus is used to describe the constitutive behavior of the tissue. Fluid flow across meniscus' pores is modeled in this paper with Darcy relation yielding a novel model of fractional‐order poromechanics, describing the evolution of the diffusion phenomenon in the meniscus. A numerical application involving an 1D confined compression test is reported to show the effect of the material hereditariness on the pressure drop evolution.
