Effect of a collar on subsidence and local micromotion of cementless femoral stems: in vitro comparative study based on micro-computerised tomography

Dominique Pioletti, Alexandre Terrier, Valérie Hélène Emilie Malfroy Camine

Purpose The aim of this study is to quantitatively compare the difference in primary stability between collarless and collared versions of the same femoral stem. Specifically, we tested differences in subsidence and micromotion. Methods Collarless and coll ...

Micromotion-induced peri-prosthetic fluid flow around a cementless femoral stem

Dominique Pioletti, Alexandre Terrier, Valérie Hélène Emilie Malfroy Camine

Micromotion-induced interstitial fluid flow at the bone-implant interface has been proposed to play an important role in aseptic loosening of cementless implants. High fluid velocities are thought to promote aseptic loosening through activation of osteocla ...

Micromotion and fluid flow around cementless femoral components in total hip arthroplasty

Valérie Hélène Emilie Malfroy Camine

Cementless total hip arthroplasty is a highly successful and reliable procedure to restore joint function and reduce pain in patients with severe osteoarthritis. Nevertheless, despite the technical advances over the last decades in the development of cemen ...

Full-field measurement of micromotion around a cementless femoral stem using micro-CT imaging and radiopaque markers

Dominique Pioletti, Alexandre Terrier, Valérie Hélène Emilie Malfroy Camine, Hannes Andreas Rüdiger

A good primary stability of cementless femoral stems is essential for the long-term success of total hip arthroplasty. Experimental measurement of implant micromotion with linear variable differential transformers is commonly used to assess implant primary ...

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

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

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 ...

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. ...
