Patellofemoral pain, stability and patellofemoral arthritis are a major problem among the younger and older aged individuals. Especially, with the populations where social habits include in load bearing daily activities with deep flexions such as kneeling and squatting. A proper understanding of the knee joint biomechanics may help in significantly improve the prevention and treatment of such disorders. Studies on tendons, cartilages, meniscus, ligaments, bones are continuously been studied and simulated analytically and experimentally with respect to tibiofemoral and patellofemoral joints to observe the behavior during different conditions that prevail within the genders. Apart from the studies mentioned, various other observational studies like arthroplasty, grafting techniques, resurfacing trochlear groove, maltracking of femur, with respect to tibia, maltracking of patella with respect to femur, patellar kinematics such as rotation, flexion, titling are constantly been studied and observed through which various inferences and contradictions evolve which leads the to explore more deeper in the field of orthopedics to determine the factors that affect and contribute to the joint. However age, gender, height, weight and the natural geometry of the each bone plays an important role in each individual leading each case to conclude with different inferences.

In recent years, numerous scientific investigations have studied the anatomical, biomechanical and functional role of structures involved in the human knee joint. The Finite Element Method (FEM) has been seen as an interesting tool to study and simulate biosystems. It has been extensively used to analyse the knee joint and various types of knee diseases and rehabilitation procedures such as the High Tibial Osteotomy (HTO). This work presents a review on FEM analysis of the human knee joint and HTO knee surgery, and discusses how adequate this computational tool is for this type of biomedical applications. Hence, various studies addressing the knee joint based on Finite Element Analysis (FEA) are reviewed, and an overview of clinical and biomechanical studies on the optimization of the correction angle of the postoperative knee surgery is provided.

As a new interdisciplinary research area, “image-based geometric modeling and mesh generation” integrates image processing, geometric modeling and mesh generation with finite element method (FEM) to solve problems in computational biomedicine, materials sciences and engineering. It is well known that FEM is currently well-developed and efficient, but mesh generation for complex geometries (e.g., the human body) still takes about 80% of the total analysis time and is the major obstacle to reduce the total computation time. It is mainly because none of the traditional approaches is sufficient to effectively construct finite element meshes for arbitrarily complicated domains, and generally a great deal of manual interaction is involved in mesh generation. This contributed volume, the first for such an interdisciplinary topic, collects the latest research by experts in this area. These papers cover a broad range of topics, including medical imaging, image alignment and segmentation, image-to-mesh conversion, quality improvement, mesh warping, heterogeneous materials, biomodelcular modeling and simulation, as well as medical and engineering applications.

Due to certain deviations of the knee anatomy, the cartilage, the ligaments or patella, some knees are less efficient to absorb shocks and transfer forces. This means the knees will wear out faster, which may result in premature necessity for knee prosthesis. The cartilage is a tissue which does not have blood vessels. As a result, the natural regeneration of the tissue is very limited. This thesis sheds light on the most common deviations of the knee anatomy. The different models are processed and simulated to examine the influence of the knee anatomy on stress and pressure in the knee joint. Patient 1 is a male with a common knee. Patient 2 is a male with a small medial condyle of the femoral cartilage. Patient 3 is a male with a large medial condyle of the femoral cartilage. Due to ethical principles it is not possible to test the influences of the knee anatomy on a living patient. Tests can be performed on cadaver knees. The tests have to be done as soon as possible after the death of the donor. Another problem is that everyone has different knees, like fingerprints they are unique. Assembling a database containing all morphological deviations is impossible. Consequently, a cooperation with engineers is started in order to simulate and examine the knee models. The aim of the present thesis is to examine the influences of the deviations of the knee anatomy before and after a meniscectomy. Using Finite Element Analysis we examine the stress and pressure points in a human knee joint. Another aim of the present paper is to develop a procedure to optimise the model for a Finite Element Analysis. We succeeded in developing an optimisation procedure. This procedure can be used to optimise any scan for a Finite Element Analysis, which was not possible with most of the existing procedures. The developed procedure can be used in any field of research in which model optimisation of a 3D object is used. Most numerical model studies in the field of biomechanics have been focusing on stress analysis of a common knee. Medical experience, however, suggests that most knee complaints arise with divergent knees. Issues of the knee joint can be predicted and anticipated in an early stage by using Finite Element Analyses.

The objective of this study was to develop a dynamic three-dimensional subject specific computational knee model by using finite element method and validate the finite element model using a validated multi-body model developed in MSC - ADAMS. The geometric input data required to create subject specific model was obtained from Magnetic Resonance Imaging of the specimen knee. The kinematic input data was obtained from simulation of the knee in a dynamic knee simulator. The three dimensional knee model was created using MR images of specimen knee. Hexahedral element meshing was performed for the construction of finite element model and ABAQUS is used for analysis purpose. Various studies were performed to identify the effects of the ABAQUS input parameters on the accuracy of the results. The finite element (FE) model was then simulated for the kinematic input obtained from a ten second squat cycle and output values for reaction force in the fixed part were recorded. The validation of FR model was conducted by comparing the results with the validated ADAMS model. Finally future improvements are suggested.

Biomechanics as an independent branch of science has gained considerable importance over the last seven decades especially owing to its valuable medical applications. Replacement of hip joint and knee components due to wear, injury or even breakage caused by accidents or due to senility. Consequently, considerable research has been intensively choosing suitable synthetic materials, conducting experiments on musculoskeletal models and carrying out an appropriate finite element analysis. However researchers have not concentrated on the detailed analysis of various forces in the bones and muscles connected to the knee and hip joints. Attention of researchers in recent past has been leaning more towards the biological and medical fields than on the mechanical computations. The present work aims at developing a representation of all the forces by the free body diagrams of the hip and knee joints. To know the force or stress distribution in the hip and knee joints of human being, one has to understand hip and knee anatomy. Knee joint is a complicated assembly; force analysis of knee is carried out by using principles of classical mechanics. Axial compressive and Muscle forces are the two forces which acts on the knee joint, is determined for three different postures of human being (standing, staircase accent and staircase decent). Hip joint is also another intricate assembly; here force analysis of hip is also carried out by using principles of classical mechanics. Axial compressive and ligament forces are the two forces which acts on the hip joint, is determined for standing and bending postures for various body weights of human being. The two major bones involved in both knee and hip joints are Tibia and Femur. In order to create 3D geometric models of these bones, image processing software is used. The input source for image processing software is CT Scan slices (DICOM images). The sequence of the slices is selected, by using scan image processing tools like segmentation, volume rendering and various filters, three dimensional models are created. Finally, fine mesh is generated to these bone models, these files are saved as .stl format and imported to ANSYS 15.0. By providing the boundary conditions to the 3D models of bones in ANSYS software, the Von-Mises stresses, normal stresses and total deformations are evaluated for both the bones, Tibia and Femur.

The finite element modelling (FEM) is a powerful instrument to study articular and tissue mechanics, as it allows variables to be manipulated and situations simulated which are difficult or impossible to evaluate clinically or experimentally. The accuracy of FE models depends on well-defined anatomy, material properties and limits. Due to the significant inter-tissue structural variability in morphology, analysis of individual and insights tends to involve a subject- specific FE modelling. Modelling efforts in in vivo were limited by difficulties in data acquisition and multimodal data analysis, including proper registration and integration of data, in finite element model construction or validation. Recent, several techniques have increased the potential to incorporate accurate tissue boundaries and morphology for image reconstruction based on subject specific finite element analysis. Hence, the proposed system uses image segmentation with 3D FEM uses the concept of image segmentation of medical images. The proposed system uses canny edge detection or improved canny edge detection for the segmentation of medical images. The canny edge method extracts the edge information of MR images of knee cartilage by incorporating a vector image model. The study also uses certain noise removal models at its pre-processing stage to remove the presence of Rician noise in MRI. Finally, the obtained segmented edges is sent as input to the 3D conversion in Ansys. The ground truth information is collected from the skilled doctors, who are experts in knee.
