An analytical model for knee ligaments

Abstract

Objective: In this work, an analytical model of porcine knee ligaments, statically loaded, is presented. Although introductory, this elastic analytical model provided an estimative of the main mechanical variables results, as longitudinal forces and displacements, and its respective longitudinal stresses and strains, in each of four knee ligaments: lateral collateral ligament (LCL), anterior cruciate ligament (ACL), posterior cruciate ligament (PCL) and medial collateral ligament (MCL). An interesting conclusion of the application of this analytical model was that the cruciate ligaments were submitted to greater forces than the collateral ones.
