Knitted Silk-Collagen Scaffold Incorporated with Ligament Stem/Progenitor Cells Sheet for Anterior Cruciate Ligament Reconstruction and Osteoarthritis Prevention

Dominique Pioletti, Weiliang Shen, Ting Zhu, Jiayun Huang

Current surgical management of anterior cruciate ligament (ACL) rupture still remains an intractable challenge in ACL regeneration due to the weak self-healing capability of ACL. Inadequate cell numbers and vascularization within the articular cavity contr ...

Efficient decellularization of equine tendon with preserved biomechanical properties and cytocompatibility for human tendon surgery indications

Dominique Pioletti, Nathalie Hirt-Burri, Jens Antons, Cédric Peneveyre, Anthony Grognuz, Pierre-Arnaud Aeberhard

Chronic and acute tendon injuries are frequent afflictions, for which treatment is often long and unsatisfactory. When facing extended injuries, matrices and scaffolds with sufficient biomechanical properties are required for surgical repair and could addi ...

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 ...

Ectopic tissue engineered ligament with silk collagen scaffold for ACL regeneration: A preliminary study

Wei Zhang, Weiliang Shen, Jiayun Huang

Anterior cruciate ligament (ACL) reconstruction remains a formidable clinical challenge because of the lack of vascularization and adequate cell numbers in the joint cavity. In this study, we developed a novel strategy to mimic the early stage of repair in ...

Standardization proposal of soft tissue artefact description for data sharing in human motion measurements

Kamiar Aminian, Arnaud Barré

Soft tissue artefact (STA) represents one of the main obstacles for obtaining accurate and reliable skeletal kinematics from motion capture. Many studies have addressed this issue, yet there is no consensus on the best available bone pose estimator and the ...

Anatomically-standardized maps reveal distinct patterns of cartilage thickness with increasing severity of medial compartment knee osteoarthritis

Julien Favre, Benedikt Fasel

While cartilage thickness alterations are a central element of knee osteoarthritis (OA), differences among disease stages are still incompletely understood. This study aimed to quantify the spatial-variations in cartilage thickness using anatomically-stand ...

Fixed and mobile-bearing total ankle prostheses: Effect on tibial bone strain

Alexandre Terrier, Xavier Crevoisier, Maïka Réane Guillemin, Caroline Sieger Fernandes

Background Total ankle replacement is associated to a high revision rate. To improve implant survival, the potential advantage of prostheses with fixed bearing compared to mobile bearing is unclear. The objective of this study was to test the hypothesis th ...

Bone orientation and position estimation errors using Cosserat point elements and least squares methods: Application to gait

Kamiar Aminian, Arnaud Barré

The aim of this study was to analyze the accuracy of bone pose estimation based on sub-clusters of three skin-markers characterized by triangular Cosserat point elements (TCPEs) and to evaluate the capability of four instantaneous physical parameters, whic ...

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 ...

Probing the Strength and Fracture Toughness of Hard Second Phases at the Micron Scale

Andreas Mortensen, Marco Cantoni, Goran Zagar, Andreas Rossoll, Martin Guillermo Mueller, Václav Pejchal, Marta Fornabaio, Lionel Michelet

It is known that the mechanical properties of composite materials and alloys are influenced by the intrinsic mechanical properties of their reinforcements or second phases. It is however challenging to determine such local properties, given their small siz ...
