“…The results of stiffness measurement depicted that E Ins and E St were region-dependent; a finding in line with previous studies (Lamela, Pelayo, Ramos, Fernández-Canteli, & Tanaka, 2013;Lu, Mow, & Guo, 2009;Tanaka et al, 2014). The stiffness in compressive loading is thought to be due to the presence of the negatively charged proteoglycans, which are able to trap water and thus contribute to the cartilage viscosity (Kuroda et al, 2009).…”

“…Also, the loss factor in compression was in the range of 0.03‐0.4 and larger than that reported in tension varying from 0.04 to 0.08 range. Similarly, the greater amount of loss factor in compression compared with that in tension for the temporomandibular joint disk can be deduced from a comparison of previous studies 22,29 . Due to the compressive nature of loading in the present work, the elastic and viscous behavior of the PDL in its dynamic response is mainly originated from the fluid phase 19 .…”

Background and Objective As the main connector of teeth to the surrounding bone, the periodontal ligament (PDL) plays an important role in absorption and distribution of physiological and para‐physiological loading. Despite the difference in the mechanical response of the PDL in tension and compression, little information is available on its viscoelastic behavior in compression. To explore the contribution of the fluid phase of the PDL, the aim of the present study was to measure its nonlinear time‐dependent behavior in compression. Material and Methods The in vitro dynamic compressive tests were carried out over a wide range of frequencies at three different preloads. Also, a generalized Maxwell model was proposed based on the experimental data to develop a viscoelastic model for subsequent computational analysis of the PDL. Results The higher values of loss factor in compression found in the range of 0.03‐0.4 than those of 0.04‐0.08 reported in tension, implies the focal role of the fluid phase in compressive dynamic response. Furthermore, the model parameters predicted that with an increase in preload, the role of the viscous components decrease, whereas the role of the elastic component increases. Conclusion The viscous effect of the PDL in compression is greater than that in tension. Also, the dependence of the relaxation modulus of the bovine PDL on the applied load indicates its nonlinear viscoelastic behavior in compression.

For instance, the PG loss is progressive and that reduces the cartilage load-bearing capacity in equilibrium.…”

Elastic, Dynamic Viscoelastic and Model-Derived Fibril-Reinforced Poroelastic Mechanical Properties of Normal and Osteoarthritic Human Femoral Condyle Cartilage

Osteoarthritis (OA) degrades articular cartilage and weakens its function. Modern fibril-reinforced poroelastic (FRPE) computational models can distinguish the mechanical properties of main cartilage constituents, namely collagen, proteoglycans, and fluid, thus, they can precisely characterize the complex mechanical behavior of the tissue. However, these properties are not known for human femoral condyle cartilage. Therefore, we aimed to characterize them from human subjects undergoing knee replacement and from deceased donors without known OA. Multi-step stress-relaxation measurements coupled with sample-specific finite element analyses were conducted to obtain the FRPE material properties. Samples were graded using OARSI scoring to determine the severity of histopathological cartilage degradation. The results suggest that alterations in the FRPE properties are not evident in the moderate stages of cartilage degradation (OARSI 2-3) as compared with normal tissue (OARSI 0-1). Drastic deterioration of the FRPE properties was observed in severely degraded cartilage (OARSI 4). We also found that the FRPE properties of femoral condyle cartilage related to the collagen network (initial fibril-network modulus) and proteoglycan matrix (non-fibrillar matrix modulus) were greater compared to tibial and patellar cartilage in OA. These findings may inform cartilage tissue-engineering efforts and help to improve the accuracy of cartilage representations in computational knee joint models.
