Anti‐inflammatory and osteogenic effects of transcutaneous electrical nerve stimulation in knee osteoarthritis rats via the regulation of the intestinal microbiota

Animal Models and Experimental Medicine, EarlyView.
Transcutaneous electrical nerve stimulation (TENS) improved knee osteoarthritis (KOA) in rats by regulating interleukin‐1β (IL‐1β), IL‐6, and IL‐8 expressions and the bone morphogenetic protein 2 (BMP‐2)/transforming growth factor β (TGF‐β) signaling pathway.

Comparison of bone and articular cartilage changes in osteoarthritis: a micro-computed tomography and histological study of surgically and chemically induced osteoarthritic rabbit models

Journal of Orthopaedic Surgery and Research, 2021
Background Osteoarthritis (OA) is a multifaceted condition that affects both the subchondral bones and the articular cartilage. Animal models are widely used as an effective supplement and simulation for human OA studies in investigating disease ...

Nerve Growth Factor is Sufficient to Cause Multiple Osteoarthritis‐Relevant Pathologic Features in Naïve Murine Knee Joints

Arthritis &Rheumatology, EarlyView.
Objective Nerve growth factor (NGF), a key mediator of pain, is increased in osteoarthritic (OA) joints. Antibodies against NGF show analgesic effects in painful knee OA, but clinical development was stopped because of side effects in the joints. Knowledge about the biologic effects of NGF on joint tissues is limited. Therefore, we explored the effects

Radiomics analysis using MR imaging of subchondral bone for identification of knee osteoarthritis

Journal of Orthopaedic Surgery and Research, 2022
Background To develop a magnetic resonance imaging (MRI)-based radiomics predictive model for the identification of knee osteoarthritis (OA), based on the tibial and femoral subchondral bone, and compare with the trabecular structural parameter-based ...

Neurovascular coupling in bone regeneration: Mechanisms, advanced biomaterials and challenges

BMEMat, EarlyView.
This figure illustrates various material strategies for neurovascularized bone regeneration, including electroactive scaffolds, ion‐loaded materials, drug delivery systems, surface modifications, cells/cell products, growth factors, and peptides. These approaches aim to synergistically promote the regeneration of neural, vascular, and bone tissues ...

Deciphering the spatial and microstructural landscape in subchondral bone remodeling of temporomandibular joint osteoarthritis

Materials & Design
The pathological remodeling of subchondral bone is a hallmark of osteoarthritis (OA), yet the spatial heterogeneity and dynamic evolution of its microstructural, compositional, and nanomechanical properties remain poorly understood.

Matching TGF‐β1 Activation With Stress‐Responsive Charge‐Reversal Hydrogel Microspheres for the Treatment of Osteoarthritis

Exploration, EarlyView.
Based on the interaction between the weakly cross‐linked disulfide bonds that break under stress and charge‐reversal messenger molecules, we herein achieved nanoparticle charge reversal under stress and constructed a stress‐responsive charge‐reversal hydrogel microsphere system using microfluidic technology.

Sel1l preserves condylar cartilage matrix homeostasis by regulating PERK signaling

Interdisciplinary Medicine, EarlyView.
Our study revealed that the expression of Sel1l was downregulated in OA cartilage and that Sel1l deficiency induced cartilage catabolism. Mechanistically, Sel1l depletion aberrantly activated PERK signaling and resulted in ER stress. PERK inhibition rescued the phenotype of Sel1l‐deficient chondrocytes and alleviated TMJOA pathogenesis.

Mapping Fatty Acid Composition in the Human Knee: Short‐Term Repeatability at 3T

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Alterations in periarticular lipid composition are implicated in musculoskeletal diseases, yet short‐term reliability of MRI‐based triglyceride composition mapping in the knee is not fully established. Purpose To evaluate 1‐week repeatability of proton‐density fat fraction (PDFF) and triglyceride fatty‐acid composition—saturated ...

Osteoarthritis alters the patellar bones subchondral trabecular architecture.

Journal of orthopaedic research : official publication of the Orthopaedic Research Society, 2017
Following the principles of "morphology reveals biomechanics," the cartilage-osseous interface and the trabecular network show defined adaptation in response to physiological loading. In the case of a compromised relationship, the ability to support the load diminishes and the onset of osteoarthritis (OA) may arise. To describe and quantify the changes
