Effects of the posterior cruciate ligament reconstruction on the biomechanics of the knee joint: a finite element analysis

Background. Previous experimental studies have been conducted to evaluate the biomechanical effects of posterior cruciate ligament reconstruction; but no consensus has been reached on the preferred method of reconstruction. Methods. The 3D finite element m ...

An ambulatory technique to assess 3D knee functions after ACL rupture

Kamiar Aminian, Julien Favre, Bijan Najafi

The anterior cruciate ligament (ACL) is most commonly injured during sporting activities such as football, ski, handball etc., when an athlete suddenly pivots or places excessive rotational force on his knee. The ACL can also be torn during severe trauma s ...

A combined RSA and FE study of the implanted proximal tibia: correlation of the post-operative mechanical environment with implant migration

Kai Johnsson

There is strong evidence to suggest that inducible displacements, migration and implant loosening are closely related to the initial mechanical environment of the implanted tibia. If this is true, then it should be possible to predict the likelihood of imp ...

A calcium phosphate implant with controlled macroporosity for anterior L5-S1 interbody fusion

In the United States approximately 50 million people suffer from low back pain. In the 20-50 years age group, this is the most important and expensive health care problem. The causes of low back pain are various. A herniated disk or spinal stenosis may tra ...

On the independence of time and strain effects in the stress relaxation of ligaments and tendons

Dominique Pioletti, Lalaonirina Rakotomanana Ravelonarivo

The hypothesis of variables separation, namely the time and the strain separation in the relaxation function, is widely used in soft tissue biomechanics. Although this hypothesis is central to several biomechanical models, only few experimental works have ...

Strain rate effect on the mechanical behavior of the anterior cruciate ligament-bone complex

Dominique Pioletti, Lalaonirina Rakotomanana Ravelonarivo, Pierre-François Leyvraz

Traction tests were performed on the bovine anterior cruciate ligament-bone complex at seven strain rates (0.1, 1, 5, 10, 20, 30, 40%/s). Corresponding stress-strain curves showed that, for a given strain level, the stress increased with the augmentation o ...

Viscoelastic constitutive law in large deformations: application to human knee ligaments and tendons

Dominique Pioletti, Lalaonirina Rakotomanana Ravelonarivo, Pierre-François Leyvraz

Traction tests on soft tissues show that the shape of the stress strain curves depends on the strain rate at which the tests are performed. Many of the constitutive models that have been proposed fail to properly consider the effect of the strain rate when ...

Viscoelastic properties of soft tissues

Dominique Pioletti

Ligaments play a central role in the stability of the knee. Due to the increase in sport activities of the young population, rupture of the anterior cruciate ligament (ACL) has become a frequent clinical problem. A surgical procedure replacing the deficien ...

Experimental and mathematical methods for representing relative surface elongation of the ACL

Dominique Pioletti, Lalaonirina Rakotomanana Ravelonarivo, Pierre-François Leyvraz

The common approach to assess the stabilizing role of the ACL in the knee has been to measure the elongation of a few marked fibers in the ligament. A comparison of the relative elongation (RE) of these marked fibers between different specimens and studies ...

Influence of soft structures on patellar three-dimensional tracking

Lalaonirina Rakotomanana Ravelonarivo, Pierre-François Leyvraz

During knee flexion, the human patella moves along a complex path resulting from the combined actions of articular contact and soft-tissue stabilization. The current study is an attempt to characterize the role of these soft structures on patellar kinemati ...
