“…Here, a Poisson’s ratio (υ) assumed to be 0.3. 19,48,49 First order tetrahedral element was selected and auto-mesh generation algorithm was performed in the ScanIP software to create a femur FE model. Then, model is exported in the suitable file format (.nas) into the HyperMesh (OptiSturct user profile) software.…”

“…Moreover, some software such as simpleware scanIP is used to obtain material properties of the femur. 19 Figure 1 shows the steps to create FE model from CT scan image by using commercialize simpleware ScanIP software. Imaging of four sheep femur specimens was performed using a Pro Speed 2, GE CT machine maintained with scan specifications (slice thickness: 1.25 mm, voltage: 100-140 kV, Tube current: 80-500 mA, Image matrix: 512 ' 512, Pixel size: 0.20 mm 3 0.20 mm) and stored in the computer in DICOM format.…”

“…11 However, the accuracy of the finite element (FE) method and the influence of different femur inclination on mechanical response in standing configuration need to be improved. Some studies have used the most common animal species such as cattle, 12,13 dog, 14,15 pig, 16 goat, 17 rat, 18 sheep [19][20][21][22][23] to evaluate biomechanical properties. In another study, the experimental method has been used to predict strain and fracture load in sheep femur.…”

The aim of this preliminary study is to predict the biomechanical properties as strain of the femur using computed tomography medical image-based finite element analysis. Further, the finite element results were compared with the experimental results for validation purpose. The main objective of the study was to establish and validate a finite element model used to analyse biomechanical properties. For this, four sheep femur specimens were used to predict normal strain in x-x direction. Computed tomography scans were taken from each femur sample. Subsequently, an accurate image-based 3D model of each femur specimen was segmented and reconstructed with its material properties. Furthermore, the experimental test was performed at 8° bone inclination in the coronal plane and a compressive load was applied at displacement rate of 0.2 mm/s to the femur head in a vertical downward direction until fracture. Consequently, the numerical results of predicted normal strain were compared with the experimental measured normal strain. The average deviation between finite element and experimental results was found to be −11.11%–20.10% in strains. Hence, it is concluded that the results obtained using finite element analysis are in good agreement with the experimental results.

“…Researchers used dual‐energy CT to obtain bone density and then used the validated density–elasticity relationship to calculate a specific Young's modulus for each element 30 . Gujar and Warhatkar (2020) introduced an image processing technique that can reduce a significant amount of modeling time based on bone density in CT images, thus deriving Young's modulus to investigate the biomechanical properties of the proximal femur bone 31 …”

“…30 Gujar and Warhatkar (2020) introduced an image processing technique that can reduce a significant amount of modeling time based on bone density in CT images, thus deriving Young's modulus to investigate the biomechanical properties of the proximal femur bone. 31 In general, the rigid model is sufficient as the constitutive relation of bone tissue in most cases, and it can reduce the calculation cost. The choice of linear elastic material for bone tissue studies involving complex loads would make the results more reliable.…”

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.
