A BiomechanicalModel Study of the Rat as a Medial Collateral Ligaments of the Knee


Ligament primarily stabilizes the diarthrodial joints and function to providestability and support during the motion of diarthrodial joints. These functions areassisted by the congruent geometry of the articulating joint surfaces andmusculotendinous forces. Ligament exhibits viscoelastic, or time-dependentbehavior, like many tissues in the body. From the medical point of view anunderstanding of the biomechanics of ligaments are crucial for the understandingof injury mechanisms and to evaluate existing surgical repair techniques. The modeof failure in ligaments depends strongly on the rate of loading. Thus, ligamentviscoelasticity is an important determinant of tissue response to loading, andviscous dissipation by the tissue modulates the potential for injury. Manymathematical models have been developed to describe the complexity of thesebehaviors that could include the microphysical interactions of various constituentsbut none of them seems to represents the overall properties of these structures.Models can be an important tool in understanding tissue structure-functionrelationships and elucidating the effects of injury, healing, and treatment. The mainobjective of this work is to study from the biomechanical point of view, thebehaviour of an example of the medial collateral ligament in response to stress andstrain effects to evaluate the biological behaviour of the ligament. The strain effectas example of the modified superposition method and analyze the results and themodel that can express the medial collateral ligament behaviour
