Microanatomical features of bovids long bones: What are the effects of mass and habitat?

Journal of Anatomy, EarlyView.
This study provides the first qualitative and quantitative exploration of inter‐bones and interspecific variations in the microanatomy of long bones in bovids in response to significant changes in body mass and habitat. Abstract Bovids are a valuable group for studying limb long bone adaptations due to differences in size and the environment that the ...

Can Knee Arthroscopy Be Considered Entirely Safe for Patients Over 50 Years Old With no Risk of Osteonecrosis? Case Series and Literature Review on Post‐Artrhoscopy Osteonecrosis of the Knee (PAONK)

Orthopaedic Surgery, Volume 17, Issue 5, Page 1378-1388, May 2025.
Post‐arthroscopy osteonecrosis is a rare complication occurring in 0.82% of cases, primarily affecting patients over 50 with degenerative meniscal tears. Early detection through MRI and conservative treatment, including bisphosphonates and weight‐bearing avoidance, proved effective in most cases, while some required surgical intervention.

Rotation matters: CT and MRI yield different tibiofemoral rotation angles in patellofemoral patients. An investigational plateau-anchored MRI method is descriptively associated with a smaller mean CT-MRI difference. [PDF]

Physical activity and joint health: Implications for knee osteoarthritis disease pathophysiology and mechanics

Experimental Physiology, EarlyView.
Abstract Knee osteoarthritis is experienced by hundreds of millions of people worldwide and is a major cause of disability. Although enhancing physical activity levels and the participation in exercise programmes has been proved to improve the debilitating illness of osteoarthritis, many do not engage in recommended levels of physical activity.

Data‐Driven Characterization of Knee Structures Using Non‐Negative Matrix Factorization of 3D Multi‐Echo UTE MRI

NMR in Biomedicine, Volume 39, Issue 6, June 2026.
Non‐negative matrix factorization (NMF) can derive tissue features in a data‐driven manner without relying on biophysical model assumptions. First‐time application of NMF to 3D multi‐echo UTE knee MRI revealed four reproducible components associated with tissues of fast and slow transverse relaxation, water–fat mixture (chemical shift), and fat tissue.

Osteology and arthrology of the ankle and tarsometatarsus of anoles (Iguania: Anolidae): not convergent with geckos but divergent from the ancestral iguanian condition

Journal of Anatomy, Volume 248, Issue 6, Page 1002-1025, June 2026.
Geckos and anoline iguanid lizards are well‐known for their possession of adhesive toepads, which are generally regarded as being convergent structures. We show that the anatomical configuration of the foot in these two lineages differs markedly and that these differences likely relate to the contrasing ways they deploy their adhesive systems and ...

COL12A1 rs970547 Polymorphism Predisposes Anterior Cruciate Ligament Injury by Inducing ER Stress and Impairing Fibroblast Function

Advanced Biology, Volume 10, Issue 5, May 2026.
The COL12A1 rs970547(A/A) polymorphism is over‐represented in Chinese male anterior cruciate ligament (ACL) injury patients. This variant destabilizes COL12A1 protein without altering transcript levels, driving compensatory upregulation of other collagen genes and inducing endoplasmic reticulum stress in ACL‐derived fibroblasts.
