“…In this study, a 3D FE model of the human tibiofemoral joint 30 was used to investigate the effect of lateral meniscectomies and asses why they are more dangerous than medial ones. The catastrophic effect of total lateral meniscectomies was demonstrated by the increases in maximum compressive and maximum shear stress on the articular cartilage, which reached values of 456 and 687%, (Fig.…”

Total meniscectomies are commonly thought to cause progressive degenerative arthrosis pathology in articular cartilage in a period of a few years because of alteration of the biomechanical environment including increased joint instability. This concern has lead to a preference for partial meniscectomies, although lateral partial meniscectomies sometimes lead to catastrophic results. We performed a three-dimensional finite element model of the human tibiofemoral joint to examine the effect of lateral meniscectomy on knee biomechanics. The results were compared to those from modeling a medial meniscectomy. Under axial femoral compressive loads, the peak contact stress and maximum shear stress in the articular cartilage increased 200% more after a lateral than a medial meniscectomy. These increased stresses could partly explain the higher cartilage degeneration observed after a lateral meniscectomy. ß

“…Increasing research using FEA are reported to study the stress distribution of tibiofemoral joint and tibiotalar joint for total knee arthroplasty, total ankle arthroplasty and postoperative rehabilitation. [50][51][52][53][54] It has also been employed to investigate the effect of numerous diseases such as diabetes, valgus deformation and tibial and fibular osteotomy on the stress distribution of joints and bones. [55][56][57] Overall, the gray values were affected not only by the scanner properties but also by the scanning environment, 58,59 which might lead to a significant difference in gray values from two scans, resulting in the differences of PMIy.…”

ARTICLES YOU MAY BE INTERESTED INMillimeter wave (220 GHz-330 GHz) characterizations of carbon nanotube films AIP Advances 8, 085110 (2018) The finite element method is playing an increasingly important role in osteoporosis screening. An accurate bone geometric model, a prerequisite for the finite element analysis, is affected by voxels. Isotropic voxel has advantages in three-dimensional reconstruction, but field of view setting usually results in anisotropic voxels. The main goal of this study was to investigate the influence of anisotropic voxel on the accuracy of three-dimensional reconstruction of bone geometric models. Sixty metatarsal bones were scanned twice with an interval of 18 months with different fields of view. We reconstructed these metatarsals and compared them. The results showed that there was no significant difference in volume, surface, length, width and height and two principal moments of inertia, indicating that anisotropic voxel caused by field of view setting has a neglectable effect on the three-dimensional reconstruction of bone geometric models, and that using finite element method based on bone geometric model reconstructed by anisotropic voxel to predict bone strength is reliable.

“…For the modelling of the bones a CAD model is used, 12 while for the ligaments and menisci the geometry is created in the program based on the available measurement results on these constituents. [13][14][15][16][17] The numerical model containing solid finite elements can be seen on Figure 4. A rigid plate connects the tibia and fibula in order to hinder the relative motions between them, practically it is functioning as a spacer.…”

“…The applied values of the material parameters are based on the work of Pena et al 17 The model of the knee joint is subjected to various knee motions in order to investigate the behavior of the collateral and cruciate ligaments. These loading cases involve 5 mm anterior and posterior tibial translation, 5° tibial valgus and varus rotation and 5° internal and external rotation ( Figure 5).…”

During the everyday life, our articulations are subjected to numerous different static and dynamic effects, in the structure of the human body they ensuring the proper attachment between the articulating bones. Within them, the various ligaments take care of the stability of the joints, their healthy functioning is essential even for ordinary daily activities. Due to the extremely serious consequences of their damage or rupture, medical science has aimed to find an adequate way to heal or replace them with natural or artificial tendons/ligaments, but so far (mostly the long term) results are not satisfactory at all. For the improvement of these procedures the better understanding and description of their mechanical behaviour is necessary. Our articulations (knee, ankle, hand and shoulder) show very difficult mechanical behaviour both from the point of loading conditions and material behaviour. Thus, the trustworthy numerical simulation of them is a very complex problem, on the top of the irregular geometry, both geometrical and material nonlinearities have to be taken into account. That is why real laboratory experiments are indispensable for the reliable numerical results. For this purpose, series of experiments have been performed on tendons and ligaments in the Biomechanical Laboratory of the BME. By the evaluation of the results different hyperelastic material models are parameterized and compared with the help of simple finite element models. On the basis of these models a three-dimensional numerical model is developed in Ansys, validated by real and numerical results. On this model, frequently occurring motions are investigated, focusing on the mechanical response of the major knee joints..
