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 ...

Intrinsic coordinate system for the tibial plateau

Dominique Pioletti, Lalaonirina Rakotomanana Ravelonarivo, Pierre-François Leyvraz

Determination of the sub-chondral bone density, or more precisely the internal density spot, can be used to evaluate the capability of a knee to sustain normal kinematics. To use this technique as a mean of knee kinematics control, the position of the inte ...

Tibial component positioning in total knee arthroplasty: bone coverage and extensor apparatus alignment

Dominique Pioletti, Reto Meuli, Pierre-François Leyvraz, Pierre Lemaire

Correct positioning of the tibial component in total knee arthroplasty (TKA) must take into account both an optimal bone coverage (defined by a maximal cortical bearing with posteromedial and anterolateral support) and satisfactory patellofemoral tracking. ...

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 ...
