Time course of bone screw fixation following a local delivery of zoledronate in a rat femoral model – a micro-finite element analysis

Dominique Pioletti, Alexandre Terrier, Ulrike Kettenberger, Adeliya Latypova

A good fixation of osteosynthesis implants is crucial for a successful bone healing but often difficult to achieve in osteoporotic patients. One possible solution to this issue is the local delivery of bisphosphonates in direct proximity to the implants, A ...

Photo-polymerization, swelling and mechanical properties of cellulose fibre reinforced poly(ethylene glycol) hydrogels

Dominique Pioletti, Pierre-Etienne Bourban, Andreas Schmocker, Azadeh Khoushabi

The application of hydrogels as load-bearing biomedical components is often limited by their mechanical properties. Often an attempt to improve a hydrogel's stiffness is accompanied by a loss of toughness and swelling properties. In this work, we show that ...

Development of an in situ controllable polymerization tool and process for hydrogel used to replace nucleus pulposus

Dominique Pioletti, Pierre-Etienne Bourban, Andreas Schmocker, Azadeh Khoushabi, Christophe Moser

Currently implants or tissue replacements are inserted either as a whole implant or by injecting a liquid which polymerizes to form a solid implant at the appropriate location. This is either highly invasive or not controllable. We developed a tool to perf ...

Photopolymerization device for minimally invasive implants: application to nucleus pulposus replacement

Dominique Pioletti, Pierre-Etienne Bourban, Andreas Schmocker, Azadeh Khoushabi, Christophe Moser

Photopolymerization is a common tool to harden materials initially in a liquid state. A surgeon can directly trigger the solidification of a dental implant or a bone or tissue filler. Traditionally, photopolymerization has been used mainly in dentistry. Ov ...

Mechanical evaluation of a tissue-engineered zone of calcification in a bone-hydrogel osteochondral construct

Dominique Pioletti, Alexandre Terrier, Jérôme Hollenstein, Robert Lie-Yuan Sah

The objective of this study was to test the hypothesis that mechanical properties of artificial osteochondral constructs can be improved by a tissue-engineered zone of calcification at the bone-hydrogel interface. Experimental push-off tests were performed ...

In-situ photopolymerization and monitoring device for controlled shaping of tissue fillers, replacements or implants

Dominique Pioletti, Andreas Schmocker, Azadeh Khoushabi, Christophe Moser

Photopolymerization is a common tool to harden materials initially in a liquid state. A surgeon can directly trigger the solidification of a dental implant or a bone or tissue filler simply by illumination. Traditionally, photopolymerization has been used ...

Variability of the pullout strength of cancellous bone screws with cement augmentation

Dominique Pioletti

Background: orthopaedic surgeons often face clinical situations where improved screw holding power in cancellous bone is needed. Injectable calcium phosphate cements are one option to enhance fixation. Methods: paired screw pullout tests were undertaken in ...

Comparison of an EMG-based and a stress-based method to predict shoulder muscle forces

Dominique Pioletti, Philippe Müllhaupt, Alexandre Terrier, Alain Farron, David Ingram, Valérie Hélène Emilie Malfroy Camine, Christoph Anselm Engelhardt

The estimation of muscle forces in musculoskeletal shoulder models is still controversial. Two different methods are widely used to solve the indeterminacy of the system: electromyography (EMG)-based methods and stress-based methods. The goal of this work ...

Strategies for improving the repair of focal cartilage defects

Dominique Pioletti, Philippe Abdel Sayed

Articular cartilage, together with skin, was predicted to be one of the first tissues to be successfully engineered. However cartilage repair remains nowadays still elusive, as we are still not able to overcome the hurdles of creating biomaterials correspo ...

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. ...

Minimally Invasive Photopolymerization In Intervertebral Disc Tissue Cavities

Dominique Pioletti, Pierre-Etienne Bourban, Andreas Schmocker, Azadeh Khoushabi, Christophe Moser

Photopolymerized hydrogels are commonly used for a broad range of biomedical applications. As long as the polymer volume is accessible, gels can easily be hardened using light illumination. However, in clinics, especially for minimally invasive surgery, it ...

The role of energy dissipation of polymeric scaffolds in the mechanobiological modulation of chondrogenic expression

Dominique Pioletti, Philippe Abdel Sayed, Salim Elias Darwiche, Ulrike Kettenberger

Mechanical stimulation has been proposed to induce chondrogenesis in cell-seeded scaffold. However, the effects of mechanical stimuli on engineered cartilage may vary substantially between different scaffolds. This advocates for the need to identify an ove ...

Does locally delivered Zoledronate influence peri-implant bone formation? – Spatio-temporal monitoring of bone remodeling in vivo

Dominique Pioletti, Julien Ston, Ulrike Kettenberger

Bisphosphonates are known for their strong inhibitory effect on bone resorption. Their influence on bone formation however is less clear. In this study we investigated the spatio-temporal effect of locally delivered Zoledronate on peri-implant bone formati ...

Intrinsic viscoelasticity increases temperature in knee cartilage under physiological loading

Dominique Pioletti, Philippe Abdel Sayed, Mohamadreza Nassajian Moghadam

Metabolism of proteoglycans and hyaluronic acid has been shown to be temperature- dependent in cartilage explants, with optimal anabolic effects between 36 1C and 38 1C. At rest, the temperature of human knee has a value of around 33 1C. We aim to show in ...

Patellar kinematics after knee arthroplasty: experimental validation of a numerical model

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

Subject-specific modelling of Total Knee Arthroplasty could be an efficient method to preoperatively evaluate surgical options. In particular, the question of the necessity of patellar resurfacing is still a debatable issue. The aim of this work was to val ...

Translation of biomechanical concepts in bone tissue engineering: from animal study to revision knee arthroplasty

Dominique Pioletti, Alexandre Terrier, Alireza Roshan Ghias, Brigitte Jolles-Haeberli

Bone defects in revision knee arthroplasty (RKA) are often located in load-bearing regions. The goal of this study was to determine if a physiologic load could be used as an in situ osteogenic signal to the scaffolds filling the bone defects. In order to a ...
