Ligament primarily stabilizes the diarthrodial joints and function to provide stability and support during the motion of diarthrodial joints. These functions are assisted by the congruent geometry of the articulating joint surfaces and musculotendinous forces. Ligament exhibits viscoelastic, or time-dependent behavior, like many tissues in the body. From the medical point of view an understanding of the biomechanics of ligaments are crucial for the understanding of injury mechanisms and to

Thus, ligament viscoelasticity is an important determinant of tissue response to loading, and viscous dissipation by the tissue modulates the potential for injury. Many mathematical models have been developed to describe the complexity of these behaviors that could include the microphysical interactions of various constituents but none of them seems to represents the overall properties of these structures. Models can be an important tool in understanding tissue structure-function relationships and elucidating the effects of injury, healing, and treatment. The main objective of this work is to study from the biomechanical point of view, the behaviour of an example of the medial collateral ligament in response to stress and strain effects to evaluate the biological behaviour of the ligament. The strain effect as example of the modified superposition method and analyze the results and the model that can express the medial collateral ligament behaviour.
