Objective: The focus of this study is to identify the significance of the ligament shape at the bone insertion sites and how it affects the stresses at the locations.
A ligament is a dense bundle of connective tissues made up of fibers that connects one bone and another bone to control joint motion and transfer load. This study was focused on stress at the bone insertion site where the ligament attaches to the bone. The present study was done to determine the importance of using nonlinear elastic properties and non-uniform geometry of the ligament when analyzed under a tensile load. A 2D axis-symmetry model was considered for the ligament and the bone was chosen to be a rigid material body and a non- linear static analysis was performed to assess the stress at the bone- ligament interface.
Results: The von Mises stresses at the insertion sites were predicted. Effect of different ligament geometry shapes was studied by comparing the stress results.
Clinical or Engineering Relevance: The results allow a better understanding of the shape of ligament morphology due to the load.
