Can lateral tenodesis improve the rotational stability of the ACL reconstruction? A finite element analysis

One of the most common knee injuries is the Anterior Cruciate Ligament (ACL) rupture with severe implications on knee stability. The usual treatment is the ACL Reconstruction (ACLR) surgery where the surgeon replaces the torn ligament with a graft in an ef ...

Surgical approaches to the capitellum: a comparative anatomic study

Alexandre Terrier, Frédéric Vauclair, Patrick Goetti

Background: Osteochondritis dissecans (OCD) of the humeral capitellum is an important cause of elbow disability in young athletes. Large and unstable lesions sometimes require joint reconstruction with osteochondral autograft. Several approaches have been ...

Morphological assessment of cartilage and osteoarthritis in clinical practice and research: Intermediate-weighted fat-suppressed sequences and beyond

Tom Hilbert

Magnetic resonance imaging (MRI) is widely regarded as the primary modality for the morphological assessment of cartilage and all other joint tissues involved in osteoarthritis. 2D fast spin echo fat-suppressed intermediate-weighted (FSE FS IW) sequences w ...

Variable Stiffness Folding Joints for Haptic Feedback

Jamie Paik, Fabio Zuliani

Origami robots composed of rigid parts with flexible joints have inherent compliance that enables deployment and reconfiguration for various shape adaptations. The major drawback of such mechanical compliance is its intrinsic softness and lack of controlla ...

Design and characterization of variable stiffness structural joints

Gennaro Senatore

This paper presents design and characterization of a new type of structural joint which can vary its stiffness through actuation. Stiffness variation is employed to control the dynamic response of frame structures equipped with such joints. The joint is ma ...

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

Dominique Pioletti, Ting Zhu, Weiliang Shen, 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 ...

Characterization of variable stiffness joints for adaptive structures

Gennaro Senatore

This paper presents a new strategy to control the structure dynamic response via a shift of the natural frequencies obtained through using variable stiffness joints. The joints are made of shape memory polymers and are fabricated through 3D printing. Stiff ...

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 ...

Joint Inertial Sensor Orientation Drift Reduction for Highly Dynamic Movements

Kamiar Aminian, Julien Chardonnens, Benedikt Fasel

Inertial sensor drift is usually corrected on a single-sensor unit level. When multiple sensor units are used, mutual information from different units can be exploited for drift correction. This study introduces a method for a drift-reduced estimation of t ...

An under-actuated origami gripper with adjustable stiffness joints for multiple grasp modes

Jamie Paik, Amir Firouzeh

Under-actuated robots offer multiple degrees of freedom without much added complexity to the actuation and control. Utilizing adjustable stiffness joints in these robots allows us to control their stable configurations and their mode of interaction with th ...

Analytical Time-Domain Solution of Plane Wave Propagation Across a Viscoelastic Rock Joint

Lyesse Laloui, Jian Zhao, Yang Zou

The effects of viscoelastic filled rock joints on wave propagation are of great significance in rock engineering. The solutions in time domain for plane longitudinal ( P-) and transverse ( S-) waves propagation across a viscoelastic rock joint are derived ...

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

Dominique Pioletti, Weiliang Shen, Wei Zhang, 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 ...

Segmentation of Foot and Ankle Complex based on Kinematic Criteria

Kamiar Aminian, Julien Favre, Hossein Rouhani, Brigitte Jolles-Haeberli, Xavier Crevoisier

Although various foot models were proposed for kinematics assessment using skin makers, no objective justification exists for the foot segmentations. This study proposed objective kinematic criteria to define which foot joints are relevant (dominant) in sk ...

Motion Synergies for Real-Time Postural Control in Virtual Environments

Daniel Raunhardt

Virtual prototyping has become an important part during the product development process. The common way to let a user interact with the virtual prototype is the use of a three dimensional virtual mannequin that is controlled by the user. These human figure ...

Osteoclastogenesis can be mechanically-induced in the peri-implant bone

Dominique Pioletti, Alexandre Terrier, Vincent Stadelmann

Total joint replacements are highly successful in relieving pain and restoring movement of damaged joints. However, the lifespan of the implants is limited. The implant’s long-term stability depends largely on the preservation of periprosthetic bone. Debri ...
