Injury simulation of anterior cruciate ligament using isogeometric analysis

Abstract

Many active sportsmen trend to get injured in knee ligaments. For that reason, singular researches on the deformations limits of Anterior Cruciate Ligament (ACL) which ensure the stability of knee have been made. Understanding in detail the running of the knee plays an important role in the design of orthotics and prosthetics, and may also modify surgical protocols. As a consequence, the injury risk will be minimized with the right knowledge of the knee functioning. The Isogeometric Analysis has the potential to facilitate the study of the most of biomechanical models, which are usually geometrically complex. In this work, we present the deformation of ACL at an injury position using the isogeometric approach (IGA), suggested by Cottrell (Isogeometric analysis toward integration of CAD and FEA. Wiley, Hoboken, 2009) and Hughes et al. (Comput Methods Appl Mech Eng 194:4135–4195, 2005). Also is emphasized the potential of IGA formulations in future of the Biomechanics.
