Patellar bone strain after total knee arthroplasty is correlated with bone mineral density and body mass index

Dominique Pioletti, Alexandre Terrier, Adeliya Latypova, Elham Taghizadeh, Philippe Büchler

Patella-related complications after total knee arthroplasty (TKA) remain a major clinical concern. Previous studies have suggested that increased postoperative patellar bone strain could be related to such complications, but there is limited knowledge on p ...

A patient-specific model of total knee arthroplasty to estimate patellar strain: A case study

Kamiar Aminian, Dominique Pioletti, Alexandre Terrier, Brigitte Jolles-Haeberli, Arash Arami, Adeliya Latypova

Inappropriate patellar cut during total knee arthroplasty can lead to patellar complications due to increased bone strain. In this study, we evaluated patellar bone strain of a patient who had a deeper patellar cut than the recommended. A patient-specific ...

A patient-specific numerical musculoskeletal knee model

Adeliya Latypova

Total Knee Arthroplasty (TKA) is a well-accepted surgical treatment of severe cases of osteoarthritis. Surgery is associated with improved pain level, knee function and health-related quality of life. Despite advances in surgical techniques and implant des ...

Influence of the patellofemoral ligaments on the patellar kinematics after TKA during squat movement

Corinne Moënnat

Osteoarthritis is a degenerative disease characterized by damage of the cartilage. A solution to this problem is total knee arthroplasty (TKA). However, there is still complication after total knee arthroplasty with patella resurfacing. In fact, most patel ...

Model-Based Estimation of Knee Stiffness

Serge Pfeifer

During natural locomotion, the stiffness of the human knee is modulated continuously and subconsciously according to the demands of activity and terrain. Given modern actuator technology, powered transfemoral prostheses could theoretically provide a simila ...

Development of patient-specific numerical musculoskeletal model to assess patellar resurfacing

Francesc Levrero Florencio

Osteoarthritis is the most common joint disease, with the knee being the most commonly affected joint. It is usually found in elder population, affecting more than a third of the people aged over 65 years old. Total knee arthroplasty (TKA) is the most sati ...

Finite element analysis of knee squat with an osteochondral defect

Ernst Remij

In this work a 3D musculoskeletal model of the knee joint, that can simulate a squat movement, has been developed. Such a model would be useful to understand the biomechanics of the knee. The model consisted of all the the bones with their articular surfac ...

Système robotique pour la mobilisation des membres inférieurs d'une personne paraplégique

Patrick Métrailler

This thesis is the first to be carried out within the framework of the project "Cyberthosis for Paraplegics" in progress at the "Laboratoire de Systèmes Robotiques" (LSRO) of the "Ecole Polytechnique Fédérale de Lausanne" (EPFL). This project, initiated in ...

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 ...

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 ...
