Free energy analysis of system comprising biased atomic force microscope tip, water meniscus and dielectric surface [PDF]

arXiv, 2005
We are concerned with free energy analysis of the system comprising an AFM tip, water meniscus, and polymer film. Under applied electrostatic potential, the minimum in free energy is at a distance greater than the initial tip--substrate separation in the absence of potential.

Macrophages‐derived small extracellular vesicles regulate chondrocyte proliferation and affect osteoarthritis progression via upregulating Osteopontin expression

Journal of Cell Communication and Signaling, Volume 19, Issue 2, June 2025.
Abstract Small extracellular vesicles (sEVs) are considered promising gene‐delivery vehicles for the treatment of osteoarthritis (OA). This study aimed to explore the molecular mechanism by which M2 macrophage‐derived sEVs (M2‐sEVs) modulate chondrocyte proliferation and apoptosis, thereby affecting OA progression.

Return‐To‐Sport Assessments After Anterior Cruciate Ligament Injury: Which Jump‐Landing Test Is Sensitive to an ACL‐Injury History Under Fatigued or NonFatigued Conditions?

European Journal of Sport Science, Volume 25, Issue 6, June 2025.
ABSTRACT Accurately identifying residual biomechanical deficits following an anterior cruciate ligament injury is critical for effective rehabilitation and safe return to sport. This study aimed to determine which of four jump‐landing tasks demonstrated the greatest sensitivity in distinguishing individuals with a history of ACL injury from healthy ...

Advancements in health informatics: finite element insights into medial open-wedge high tibial osteotomy and lateral meniscal tears

Mathematical Biosciences and Engineering
Knee medial compartment osteoarthritis is effectively treated by a medial open-wedge high tibial osteotomy (MOWHTO). The feasibility and safety of MOWHTO for mild lateral meniscal tears are unknown.

The transepicondylar distance is a reliable and easily measured parameter for estimating femoral cartilage surface area using MRI

Knee Surgery, Sports Traumatology, Arthroscopy, Volume 33, Issue 6, Page 1967-1974, June 2025.
Abstract Purpose Different cartilage repair techniques are widely used to regenerate cartilage, such as autologous chondrocyte implantation (ACI), osteochondral autograft transfer, microfracturing and minced cartilage. Defect size is a key parameter for selecting the best procedure to repair cartilage.

Varied influence of the femoral or tibial component on quadriceps angles: Verified by imaging studies

Acta Orthopaedica et Traumatologica Turcica, 2019
Objective: The aim of this study was to evaluate the varied influence of femoral or tibial component on Quadriceps angles (Q-angle) measured with magnetic resonance image (MRI) and full-length standing scanogram (FLSS) techniques.

Modeling Surface Wave Propagation over Meniscus and Scattering by a Surface-piercing Barrier [PDF]

arXiv
Recent experiments have revealed that the meniscus formed near a surface-piercing barrier can significantly alter the propagation and scattering of capillary-gravity surface waves, beyond what classic flat-surface models predict. In particular, wave transmission increases as the barrier pulls up the meniscus, then drops sharply if the barrier is raised

Specific fibre areas in the femoral footprint of the posterior cruciate ligament act as a major contributor in resisting posterior tibial displacement: A biomechanical robotic investigation

Knee Surgery, Sports Traumatology, Arthroscopy, Volume 33, Issue 6, Page 2010-2018, June 2025.
Abstract Purpose Similar to the anterior cruciate ligament, the femoral footprint of the posterior cruciate ligament (PCL) is composed of different fibre areas, possibly having distinct biomechanical functions. The aim of this study was to determine the role of different fibre areas of the femoral footprint of the PCL in restraining posterior tibial ...

Concomitant Opening-Wedge Distal Femoral Osteotomy and Anterior Closing-Wedge Proximal Tibial Osteotomy With Tunnel Bone Grafting for the First Stage of a Revision Anterior Cruciate Ligament Reconstruction

Arthroscopy Techniques
Multiple risk factors for anterior cruciate ligament (ACL) reconstruction graft failure have been reported, including improper tunnel placement, unrepaired meniscus or ligamentous injuries, and coronal/sagittal malalignment. Various biomechanical studies
