Thoughts on cartilage tissue engineering: A 21st century perspective

Dominique Pioletti, Peyman Karami, Theofanis Stampoultzis

In mature individuals, hyaline cartilage demonstrates a poor intrinsic capacity for repair, thus even minor defects could result in progressive degeneration, impeding quality of life. Although numerous attempts have been made over the past years for the ad ...

Damage-driven strain localisation in networks of fibres: A computational homogenisation approach

Pablo Antolin Sanchez, Felipe Figueredo Rocha

In many applications, such as textiles, fibreglass, paper and several kinds of biological fibrous tissues, the main load-bearing constituents at the micro-scale are arranged as a fibre network. In these materials, rupture is usually driven by micro-mechani ...

A Review on Finite Element Modeling and Simulation of the Anterior Cruciate Ligament Reconstruction

Dimitar Yuriev Stanev

The anterior cruciate ligament (ACL) constitutes one of the most important stabilizing tissues of the knee joint whose rapture is very prevalent. ACL reconstruction (ACLR) from a graft is a surgery which yields the best outcome. Taking into account the com ...

Influence of Bovine Serum Albumin (BSA) on the Tribocorrosion Behaviour of a Low Carbon CoCrMo Alloy in Simulated Body Fluids

Stefano Mischler, Shoufan Cao

Tribocorrosion, as the interaction between mechanical wear and electrochemical corrosion, has been found to be the main problem causing the failure and limiting the lifetime of metal-on-metal artificial hip joints. Better understanding of the tribocorrosio ...

Tailoring the Mechanical Properties of Tissue Engineering Scaffolds made from Decellularized Cartilage

Jens Antons

Due to its limited regeneration capacity, articular cartilage defects are considered a frequent clinical problem. Initial cartilage defects, if left untreated, will progress in severity over time and can eventually lead to degenerative joint diseases such ...

Efficacy of pulsed electromagnetic fields and electromagnetic fields tuned to the ion cyclotron resonance frequency of Ca2+ on chondrogenic differentiation

Philippe Renaud, Harald Van Lintel

Previous studies provide strong evidence for the therapeutic effect of electromagnetic fields (EMFs) on different tissues including cartilage. Diverse exposure parameters applied in scientific reports and the unknown interacting mechanism of EMF with biolo ...

Tribocorrosion under fluid lubrication : modeling wear of CoCrMo artificial hip joints

Shoufan Cao

Wear is still the key problem causing the failure and limiting the lifetime of artificial hip joints, especially for the polymer acetabular cup in the metal-on-polymer and ceramic-on-polymer articulations. To reduce the wear, metal-on-metal articulation ha ...

In vivo electrochemical corrosion study of a CoCrMo biomedical alloy in human synovial fluids

Stefano Mischler

The present study was initiated with the aim to assess the in vivo electrochemical corrosion behaviour of CoCrMo biomedical alloys in human synovial fluids in an attempt to identify possible patient or pathology specific effects. For this, electrochemical ...

Tribocorrosion of passive metals in the mixed lubrication regime: theoretical model and application to metal-on-metal artificial hip joints

Stefano Mischler, Shoufan Cao

Wear is a key problem limiting the lifetime and performance of total hip arthroplasty. The synovial fluid, acting as lubricant, can alleviate the wear of implants but also introduces corrosion. The interaction of mechanical wear and electrochemical corrosi ...

Impact of synovial fluid flow on temperature regulation in knee cartilage

Dominique Pioletti, Philippe Abdel Sayed, Valérie Hélène Emilie Malfroy Camine, Mohamadreza Nassajian Moghadam

Several studies have reported an increase of temperature in cartilage submitted to cyclic sinusoidal loading. The temperature increase is in part due to the viscous behavior of this tissue, which partially dissipates the input mechanical energy into heat. ...

Monitoring the effects of dexamethasone treatment by MRI using in vivo iron oxide nanoparticle-labeled macrophages

Heinrich Hofmann, Lionel André Maurizi, Géraldine Sylvie Coullerez

Introduction: Rheumatoid arthritis (RA) is a chronic disease causing recurring inflammatory joint attacks. These attacks are characterized by macrophage infiltration contributing to joint destruction. Studies have shown that RA treatment efficacy is correl ...

Dissipation Can Act as a Mechanobiological Signal in Cartilage Differentiation

Dominique Pioletti, Arne Christian Vogel, Philippe Abdel Sayed

Knee cartilage is a soft tissue having viscoelastic properties. Under cyclic loadings, viscoelastic materials dissipate mechanical loadings through heat generation. In knee cartilage, this heat might not be convected because of the tissue avascularity, res ...

Peptide ligands for targeting and retention of nanoparticles and protein therapeutics in articular cartilage

Osteoarthritis (OA) is one of the most common causes of pain and disability. Currently, non-surgical treatment is limited to analgesic and anti-inflammatory drugs, which are not capable of either modifying the disease process or regenerate damaged parts in ...

Thrombin-sensitive photodynamic agents: A novel strategy for selective synovectomy in rheumatoid arthritis

Hubert van den Bergh

Protease-sensitive macromolecular prodrugs have attracted interest for bio-responsive drug delivery to sites with up-regulated proteolytic activities such as inflammatory or cancerous lesions. Here we report the development of a novel polymeric photosensit ...

Fast collision detection methods for joint surfaces

Daniel Thalmann, Ronan Boulic

In the recent years medical diagnosis and surgery planning often require the precise evaluation of joint movements. This has led to exploit reconstructed three-dimensional models of the joint tissues obtained from CT or MR Images (for bones, cartilages, et ...
