Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Ce travail a pour but de mieux comprendre la biomécanique des prothèses de genou. En particulier, on s'intéressera à l'effet de la congruence des surfaces articulaires (tibia-fémur) sur la stabilité (translation antéropostérieure) du genou prothétique. Une ...
Articular cartilage plays important roles in weight-bearing, lubrication, and load distribution in articulating joints. The tissue is mostly extracellular matrix (>90% by volume) that is synthesized and remodeled by cells (chondrocytes) embedded within. Ad ...
Background. Different rehabilitation exercises such as open-kinetic-chain flexion and extension exercises are currently employed in non-operative and post-operative managements of joint disorders. The challenge is to strengthen the muscles and to restore t ...
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 ...
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 ...
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 ...
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. ...
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 ...
Injuries to the meniscus are often treated by partial or total meniscectomy, which is known to be associated with detrimental changes in joint function, ultimately increasing the risk of early degenerative joint diseases. Surgical approaches currently in u ...
Computer Graphics came into the medical world especially after the arrival of 3D medical imaging. Computer Graphics techniques are already integrated in the diagnosis procedure by means of the visual tridimensional analysis of computer tomography, magnetic ...
