Repair of a Chronic Quadriceps Tendon Re‐rupture With Semitendinosus Tendon Autograft Augmentation

open access: yesArthroscopy Techniques, Volume 14, Issue 11, November 2025.
Abstract The quadriceps tendon (QT) functions as one of the primary knee extensor mechanisms. The risk of QT tendinopathy increases with age, which also impacts the risk of QT rupture. This injury typically occurs as a result of an abrupt eccentric contraction with knee hyperflexion. A QT rupture has detrimental effects on quality of life and function.

Combined Ipsilateral Revision Quadriceps Tendon Repair and Patellar Tendon Allograft Reconstruction Technique for Floating Patella

open access: yesArthroscopy Techniques, Volume 14, Issue 10, October 2025.
Abstract Extensor mechanism disruptions of the knee are significant injuries that have the potential to result in pain and dysfunction unless surgically repaired in the acute setting. Subacute or chronic injuries and revision surgery result in added complexity.

Influence of Glacial Isostatic Adjustment on Intraplate Stress and Seismicity in Eastern North America in the Presence of Pre‐Existing Weak Zones

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.
Abstract Eastern North America has hosted significant historical earthquakes, where seismicity clusters along tectonically inherited structures. Using the spherical finite‐element code CitcomSVE and fully 3D viscosity structure, we model the intraplate stress response to glacial isostatic adjustment (GIA) using ICE‐6G, both with and without low ...

Lowermost Mantle Flow at Thermochemical Piles Constrained by Shear Wave Anisotropy: Insights From Combined Geodynamic and Mantle Fabric Simulations at Global Scale

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.
Abstract Seismic anisotropy is observed in the lowermost few hundred kilometers of the mantle. This anisotropy likely signifies strong deformation, possibly caused by mantle flow interacting with the edges of Large Low‐Shear‐Velocity Provinces (LLSVPs) or by the ascent of mantle plumes originating near these regions.
