Abstract
One of the challenges in creating a 3D human knee joint model is accurately defining the area of interest. Prior studies employed simplified bone models, which could potentially compromise the precision of the analysis, posing a contemporary issue. To address this, a multi-step technique was adopted to mitigate the problem and enhance the accuracy of the human knee joint model using analytical and simulation methods. In this endeavour, healthy male knee scanning data were used to reconstruct 3D knee models. Various types of units were employed to segment different parts of the bones. The knee model comprised distinct bone components, and cartilages were created by removing and distinguishing bone layers. For representation, the knee models of a person in both a standing position and while ascending stairs were represented by linear spring elements. Extensive analysis calculations were conducted to validate these models.
