... validation sensitivity analysis muscle ligament cartilage meniscus The knee is one of the most complex joints in the body and plays a critical role in daily locomotion [ 1 ]. It is comprised of two separate joints—the tibiofemoral joint and patellofemoral joint—each of which is often affected...

.... The inconsistencies in the measured properties complicate the next step of the experimental procedure, which is the constitutive modeling of cervical spine ligaments. Within the framework of hyperelasticity, the toe and linear soft tissue regions have been well modeled [ 36–39 ]. Recently, constitutive models...

.... The objective of this study was to study the effect of boundary condition on the pelvic biomechanics predictions. A 3D FE model of a pelvis using subject-specific estimates of intact bone structures, main ligaments and bone material anisotropy by computed tomography (CT) gray value was developed and validated...

...Martin L. Tanaka; Charles A. Weisenbach; Mark Carl Miller; Laurel Kuxhaus Developing appropriate mathematical models for biological soft tissues such as ligaments, tendons, and menisci is challenging. Stress-strain behavior of these tissues is known to be continuous and characterized...

... points on the path of motion in a timely fashion for repeatable path accuracy are of particular importance. Use of the system developed will lead to a better understanding of the mechanical environment of joints and ligaments in vivo. 20 10 2009 28 01 2010 16 02 2011 17 05 2011 17...

...Joseph M. Iaquinto; Jennifer S. Wayne The aim of this work was the design and evaluation of a computational model to predict the functional behavior of the lower leg and foot/ankle complex whereby joint behavior was dictated by three-dimensional articular contact, ligamentous constraints, muscle...

...Michelle L. Zec; Paul Thistlethwaite; Cyril B. Frank; Nigel G. Shrive Ligaments are regularly subjected to repetitive loading in vivo. Typically, mechanical studies focus on repetitive loading protocols of short duration, while those characterizing damage accumulation over a longer duration (i.e...

..., actual in vivo loading conditions of the joint remain unknown. A method for determining in vivo ligament loads by reproducing joint specific in vivo kinematics using a robotic testing apparatus is described. The in vivo kinematics of the ovine stifle joint during walking were measured with 3D optical...

...Trevor J. Lujan; Michelle S. Dalton; Brent M. Thompson; Benjamin J. Ellis; Jeffrey A. Weiss The knee joint is partially stabilized by the interaction of multiple ligament structures. This study tested the interdependent functions of the anterior cruciate ligament (ACL) and the medial collateral...

...P. Vena; D. Gastaldi; R. Contro This paper presents a constitutive model for predicting the nonlinear viscoelastic behavior of soft biological tissues and in particular of ligaments. The constitutive law is a generalization of the well-known quasi-linear viscoelastic theory (QLV) in which...
