1-3-Existing ResearchThe joint of the knee is considered one of the most essential and critical joints of the humananatomy. The knee joint is additionally known as the ‘hinge joint’. The hinge joint performs severalactivities that include standing, sitting, flexion, extension, bending, or walking. In all theaforementioned activities, the extent of load acting on the knee joint varies (Machado et al. 2010).The human knee joint primarily comprises of three main components: the tibia, the femur, and thepatellar component along with a deformed body. The people who suffer from the pain of the kneeor trauma to the knee joint, risk of injury to the knee, and individuals involved in activities of sportsthat result in mechanical wear and tear of the knee joint. Improper functioning or dysfunction of theknee joint occurs due to defects in the knee. Such defects of the knee that cause failure of activityoften lead to operative solutions. The operative solution involves knee prosthesis or the surgicalremoval of various defective components of the joint followed by the replacement of thecomponent with an artificial implant. The defect of the knee is primarily carried out by methods suchas X-ray, CT-scan procedure, or MRI imaging techniques. Most often, the knee replacement surgeryis performed by making a small incision of about 3 or 4 inches (Hernandez-Vaqueroet al. 2010).According to a study, Peña et al.study (2006), several models of computation are an effectivealternative method to the analysis of several biomechanical quantities. These methods may beemployed for the reduction of cost, time, and efficiency of machinery. Particularly, the method offinite element or FE can be used to provide results of high medical accuracy and relevance (Peña etal. 2006). In a study by Herrera et al., (2012), the technique of FE simulation usually allows for thecalculation of the variations in the special and temporal values of stress, strain, and areas and forcesof contact that are present in different situations that are easy to reproduce, with high precision(Herrera et al. 2012).A study by Kiapouret al., (2014), focused on the reliability and precision of results of the model of FE.The study concentrated on three primary factors that determine the accuracy of the FE model. Thefactors were found to be the complexity in the geometrical configuration, the interaction that occursbetween the various parts of the model, and defining the material properties that represent thecorrect mechanical behaviour of the structure that has to be modelled (Kiapouret al. 2014).Thus, the study suggested that the application of the method of FE analysis on complex structurespresents several challenges caused by the various distinctive features of the model. However, in themethod of FE modelling, the maintenance of a stringent balance between the complexity of themodel and the efficiency of computation is absolutely essential. Upon the successful achievement ofsuch a balance, the method of FE analysis has been proven as a powerful tool for the provision ofbiomechanical information that is of extreme use in the context of clinical evaluation (Xieet al.2009). A study by Adouni, M et al, (2012) focused on the investigation of the computational modelsof FE. The analysis of the knee by the FE model was analysed in this study, and the diverseparameters were considered that included the degree of complexity, the variables of the study, themodels of material definitions, and cases of loading of the knee joint that results in the simulation.The parameters chosen for the study define the analysis and the nature of assessment. The natureof analysis may vary as being static or quasi-static (Xieet al. 2009), or dynamic states (Adouni et al.2009).1|P a g e
