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 ...

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. ...

Displacements of the tibial tuberosity - Effects of the surgical parameters

Dominique Pioletti, Lalaonirina Rakotomanana Ravelonarivo, Pierre-François Leyvraz

A three-dimensional computer model is used, based on the finite element method, to investigate the effects of 1-, 1.5-, and 2-cm tibial tubercle elevations and of 0.5- and 1-cm medial displacements of the tuberosity performed with different bone shingles. ...

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 ...

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 ...
