An Anomalous Attachment of the Medial Meniscus Posterior and Anterior Roots Mimicking a Bucket Handle Meniscus Tear: A Case Report and Review of the Literature [PDF]

Introduction: Anomalous medial menisci are rare entities compared to their lateral counterparts. These anomalies include atypical insertions, most commonly into the anterior cruciate ligament, and discoid variants among others.

Improved arthroscopic one-piece excision technique for the treatment of symptomatic discoid medial meniscus

Journal of Orthopaedic Surgery and Research, 2017
Background Discoid medial meniscus is an extremely rare abnormality of the knee. During arthroscopic meniscectomy for symptomatic discoid medial meniscus, it is difficult to remove the posterior portion of the meniscus because of the confined working ...

Biomimetic Gradient Hydrogels Regulate Osteochondral Regeneration Microenvironment Remodeling via Spatiotemporal Programming Engineering

Advanced Science, EarlyView.
Electric field‑driven continuous gradient hydrogel GHZF4 achieves spatiotemporal growth factor release, modulates immune microenvironment, angiogenesis and osteochondral differentiation. It realizes cell‑free functional osteochondral repair in rat/rabbit models, offering a promising biomimetic strategy for gradient tissue regeneration.

Interface‐Directed High Fluorescence Efficiency Two‐Dimensional Molecular Crystals With Surface‐Exposed Active Sites

Advanced Science, EarlyView.
Here, we designed the Me‐FBSe molecule and prepared a two‐dimensional molecular crystal via liquid‐liquid interface assembly. The crystal preserves the high photoluminescence quantum while simultaneously ensuring the high‐density surface exposure of active sites.

Development of decellularized meniscus using closed sonication treatment system: as potential scaffolds for orthopedics tissue engineering applications [PDF]

, 2019
Purpose: Meniscus is a fibrocartilagenous tissue that cannot effectively heal due to its complex structure and avascular zone present. Thus, tissue engineering and regenerative medicine offer an alternative for the regeneration of meniscus tissues using ...

Kaempferol Attenuates Spaceflight‐Associated Knee Cartilage Degradation by Targeting NOX4‐Mediated Mitochondrial Dysfunction

Advanced Science, EarlyView.
We have shown that both simulated and actual spaceflight contribute to cartilage degradation in the knees of mice. Using RNA sequencing and bioenergetic profiling, we identified NADPH oxidase 4 (NOX4) as a key factor driving these changes. Additionally, we found that kaempferol, a naturally occurring flavonoid that binds directly to NOX4, reduces ...

Basics of the Meniscus [PDF]

, 2017
The meniscus is a fibro-cartilaginous tissue located between the femoral condyles and the tibial plateau in the knee. The presence of the meniscus tissue is vital for the proper function of the knee.

HMGCR‐Driven Cholesterol Metabolism Promotes Osteoarthritis Progression by Accelerating Synovial Fibroblast Senescence

Advanced Science, EarlyView.
In the pathological context of osteoarthritis (OA), the phosphorylation of AKT1 at Ser473 enhances its binding to Lys140 of Insig1, which facilitates the formation of AKT1–Insig1 complex. Subsequently, the activation of AKT1 promotes the phosphorylation of Insig1 at Ser189, potentially enhancing the dissociation of Insig1 from sterol regulatory element‑
