Biomechanical evaluation of intra-articular and extra-articular procedures in anterior cruciate ligament reconstruction: A finite element analysis

Background. Intra-articular techniques (single and double bundles) are the most widely used procedures for the anterior cruciate lig- ament reconstruction. Lemaire introduced in 1967 the extra-articular techniques, and combined intra-articular and extra-ar ...

A new ambulatory system for comparative evaluation of the three-dimensional knee kinematics, applied to anterior cruciate ligament injuries

Kamiar Aminian, Julien Favre, Bijan Najafi

The aim of this study was to develop an ambulatory system for the three-dimensional (3D) knee kinematics evaluation, which can be used outside a laboratory during long-term monitoring. In order to show the efficacy of this ambulatory system, knee function ...

A force-sensing device for assistance in soft-tissue balancing during knee arthroplasty

Denis Crottet

Nowadays, the large majority of the instrumentation for orthopaedic surgery consists of mechanical tools with varying degrees of complexity. To increase the accuracy and the safety of orthopaedic interventions, sensors and computers were recently introduce ...

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

Alexandre Terrier

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 ...

Development of a force amplitude- and location-sensing device designed to improve the ligament balancing procedure in TKA

Hannes Bleuler, Thomas Maeder, Denis Crottet

A force-sensing device to intraoperatively measure knee joint forces and moments to improve the ligament balancing procedure during total knee arthroplasty has been developed. It consists of two sensitive plates, one for each condyle, a tibial base plate a ...

How plate positioning impacts the biomechanics of the open wedge tibial osteotomy; a finite element analysis

Dominique Pioletti, Pierre-Etienne Bourban, Luc Blecha

A numerical model of the medial open wedge tibial osteotomy based on the finite element method was developed. Two plate positions were tested numerically. In a configuration, (a), the plate was fixed in a medial position and (b) in an anteromedial position ...

In-vitro evaluation of a force-sensing device for ligament balancing in TKA

Hannes Bleuler, Thomas Maeder, Denis Crottet

Component loosening and instability are common causes of dysfunction after Total Knee Arthroplasty (TKA) and it is generally assumed that such complications are due to tibio-femoral misalignment or ligamentous imbalance. During the surgery, the ligamentous ...

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 ...

In-vitro validation of a device measuring the tibio-femoral contact forces and moments for efficient assistance during ligament balancing in total knee arthroplasty

Hannes Bleuler, Thomas Maeder, Denis Crottet

Ligament balancing in total knee arthroplasty is believed to have an important influence on the joint stability and prosthesis lifetime. In order to provide quantitative information and assistance during the ligament balancing phase, a device that intraope ...

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 ...
