Architecture‐Engineered Semi‐Crystalline Microporous Polymer Membranes for Precise Molecular Separation

Advanced Science, EarlyView.
Guided by a Random Forest model, a π–π‐driven ordered stacking strategy deploys functionally distinct substructures to restrict chain segment motion and increase free volume, while preserving the intermolecular interactions that maintain structural integrity.

Modified Arthroscopic Brostrom Procedure With Bone Tunnels

Arthroscopy Techniques, 2016
The open anatomic repair of the anterior talofibular and calcaneofibular ligaments (modified Brostrom procedure) is widely accepted as the standard surgical stabilization procedure for lateral ankle instability that does not respond to conservative ...

Combined Intra‐ and Extra‐articular Reconstruction of the Anterior Cruciate Ligament: The Reconstruction of the Knee Anterolateral Ligament

Arthroscopy Techniques, 2015
Abstract We present a new technique for the combined intra‐ and extra‐articular reconstruction of the anterior cruciate ligament. Intra‐articular reconstruction is performed in an outside‐in manner according to the precepts of the anatomic femoral tunnel technique.

A Decoy‐Receptor‐Armed Biomimetic Nanotherapeutic With Inherent Tropism for Conserved Pathogenic Macrophages for Treating Osteoarthritis and Intervertebral Disc Degeneration

Advanced Science, EarlyView.
A biomimetic doppelgänger nanosystem neutralizes extracellular inflammatory cytokines and silences intracellular pyroptosis, reprogramming pathogenic macrophages to attenuate both joint and spine degeneration. ABSTRACT Osteoarthritis (OA) and intervertebral disc degeneration (IVDD) are debilitating musculoskeletal disorders driven by shared ...

Cellular and molecular response to mechanical articular cartilage injury [PDF]

, 2010
PhDJoint injures frequently involve structural damage to articular cartilage and the underlying subchondral bone. The outcome of acute joint surface defects (JSD) varies from spontaneous healing to the development of post-traumatic osteoarthritis (PTOA).

Contribution of postnatal collagen reorientation to depth-dependent mechanical properties of articular cartilage [PDF]

, 2011
The collagen fibril network is an important factor for the depth-dependent mechanical behaviour of adult articular cartilage (AC). Recent studies show that collagen orientation is parallel to the articular surface throughout the tissue depth in perinatal

Engineered Cyanobacteria‐Hydrogel Microecological System for Oxygen Reprogramming Synergizes Immunomodulation With Anabolism in Osteoarthritis Therapy

Advanced Science, EarlyView.
An injectable cyanobacteria‐laden hydrogel enables light‐dependent oxygen metabolism engineering for osteoarthritis therapy. Photosynthetic oxygen release under red light irradiation suppresses synovial inflammation via HIF‐1α inhibition and M2 macrophage polarization, while respiratory oxygen consumption in darkness stabilizes chondrocyte HIF‐1α to ...

A novel arthroscopic classification of deltoid ligament injuries in ankle fractures and its impact on surgical management

Journal of the Foot & Ankle
Introduction: Ankle fractures have an annual incidence of 0.1%-0.2% and may be associated with deltoid ligament injury in up to 58% of cases. The true prevalence and severity of these lesions may be underestimated when assessed using indirect diagnostic
