Multi‐Tissue Crosstalk Regulating Meniscus Healing Under Inflammation and Physiological Loading

open access: yesAdvanced Science, EarlyView.
Using a novel Meniscus‐on‐a‐chip (MoC) model integrated with a meniscus‐specific bioreactor, this study investigated the roles of multi‐tissue crosstalk that regulates injury, healing, and degeneration of the meniscus injury under inflammation and pathophysiological loading.

Liquid‐Responsive Shape‐Memory Nanofiber‐Reinforced Scaffolds for Cartilage Repair

open access: yesAdvanced Science, EarlyView.
A liquid‐responsive shape‐memory, nanofiber‐reinforced QCG scaffold combines conformal defect filling, an aligned architecture that is structurally permissive for endogenous cell infiltration, and sustained KGN release. This integrated design enhances BMSC viability, migratory activity, and chondrogenic differentiation and promotes hyaline cartilage ...

Open knee dislocation with a patellar tendon rupture: Result of staged surgical repair

open access: yesSAGE Open Medical Case Reports, 2019
Knee dislocation with concomitant multiligament injury is a rare and devastating injury. We report the successful repair of a rare case of open knee dislocation with concomitant multiligament injury and patellar tendon rupture of an 18-year-old male due ...

Persistent Zn2+ Influx‐Mediated Deacetylation of ANXA2 Regulates the “Zn2+‐Autophagic Flux” and Alleviates Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
Zinc transporter SLC39A14 sustains intracellular Zn2+ levels to activate SIRT3‑dependent ANXA2 deacetylation at K302. This modification weakens ANXA2‑mTOR binding and releases autophagic‑flux suppression in nucleus pulposus cells. Dysregulated Zn2+ homeostasis disrupts this axis to drive intervertebral disc degeneration.

Brain volume alterations in patients with chronic knee-joint injury: A cross-sectional analysis based on vehicle-mounted mobile magnetic resonance imaging data

open access: yesNeural Regeneration Research
Although chronic musculoskeletal pain is reportedly associated with changes in brain structural plasticity, the controlled settings of most studies to date may not reflect the brain characteristics of patients in weight-bearing conditions.

H4K12 Lactylation Regulates NDUFS7 to Drive Microglia Reverse Electron Transport in Spinal Cord Injury

open access: yesAdvanced Science, EarlyView.
Lactate accumulation after SCI promotes H4K12la lactylation, which upregulates NDUFS7, triggering mitochondrial RET and ROS, enforcing pro‐inflammatory microglial polarization. MM@mPTC, a biomimetic nanotherapeutic, degrades LDHA in activated microglia, reducing H4K12la lactylation and blocking RET, thus curbing ROS, fostering a reparative phenotype ...

A Novel Method for Calculation of Knee Deformation Angles in Clinical and Sport Biomechanics

open access: yesCentral European Journal of Sport Sciences and Medicine, 2016
Biomechanical analyses seek to improve understanding of the mechanisms of knee injury and to find ways to reduce knee injury incidence. Many clinical biomechanics researchers use a standard kinematic adopted from Newington Children’s Hospital ...

Digoxin Alleviates Osteoarthritis by Inhibiting Macrophage Extracellular Trap Formation via Disruption of the LSP1‐SOD1 Interaction

open access: yesAdvanced Science, EarlyView.
Synovial macrophages in osteoarthritis upregulate LSP1, which directly binds and inhibits SOD1, triggering a redox imbalance that activates both NOX and mitochondrial ROS pathways. This cascade drives the release of macrophage extracellular traps (METs), causing chondrocyte damage and disease progression.

Analysis of the biomechanical characteristics of the knee joint with a meniscus injury

open access: yesHealthcare Technology Letters, 2018
The knee joint is one of the most important joints in the human body. The meniscus is a half-moon cartilage which locates between the medial and lateral condyle of the thighbone and the medial and lateral condyle of the shin in the knee joint, and it has
