Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

Advanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Optimization of Subscapularis Tendon Repair in Stemless Shoulder Arthroplasty Using a Resorbable Pressure-Dissipating Onlay Suture Disk Implant

Arthroscopy Techniques
Successful subscapularis repair in stemless shoulder arthroplasty is crucial to reduce complications and improve postoperative function. As stemless shoulder arthroplasty continues to grow in popularity, several subscapularis tendon repair techniques are

Kelvin Probe Force Microscopy in Bionanotechnology: Current Advances and Future Perspectives

Advanced Materials, EarlyView.
Kelvin probe force microscopy (KPFM) enables the nanoscale mapping of electrostatic surface potentials. While widely applied in materials science, its use in biological systems remains emerging. This review presents recent advances in KPFM applied to biological samples and provides a critical perspective on current limitations and future directions for

Soft Skins With Reversible Thickness Morphing: Materials, Mechanisms, and Applications

Advanced Materials, EarlyView.
Evolution of electronic skin (e‐skin) technologies toward adaptive, multifunctional soft skins. Phase I highlights early rigid and discrete sensory interfaces. Phase II shows the transition toward flexible, stretchable, and large‐area e‐skin. Phase III captures the emergence of computational e‐skin.

Disruption of a Patellar Tendon Repair [PDF]

Journal of Orthopaedic & Sports Physical Therapy, 2012
The patient was a 38-year-old man evaluated by a physical therapist 14 weeks after repair of the left patellar tendon. The physical therapist requested radiographs, which revealed findings consistent with a patellar tendon retear. The radiologist recommended further evaluation with magnetic resonance imaging, which showed a left patellar tendon tear.

Dynamic Mechanical Loading Modulates Extracellular Vesicle Production and Cargo in Meniscus Fibrochondrocytes

Advanced Materials Interfaces, EarlyView.
Dynamic mechanical loading of outer meniscus fibrochondrocytes increases extracellular vesicle (EV) yield and alters EV composition. When applied to progenitor cells, these mechanically primed EVs modulate the expression of matrix‐related genes.

The Outcome after Arthroscopic Massive Rotator Cuff Repair according to the Repair Technique - Comparison of Tendon to Tendon Repair versus Tendon to Tendon and Bone to Tendon Repair -

The Journal of the Korean Orthopaedic Association, 2009
Purpose: We evaluated the functional outcomes after arthroscopic repair of a massive tear between the tendon to tendon (TT) repair technique and the tendon to tendon and bone to tendon (TTBT) repair technique. Materials and Methods: From March, 2002 to January, 2007, 43 cases of arthroscopic massive rotator cuff repair were evaluated.

Fabrication of Fibers With Complex Features Using Thermal Drawing of 3D‐Printed Preforms

Advanced Materials Technologies, EarlyView.
3D printing enables rapid fabrication of macroscale polymer preforms with complex geometries. Thermal drawing then scales these structures into long fibers while preserving micron‐scale cross‐sectional features. This workflow provides a fast, low‐cost route to functional fibers with tailored geometries and material combinations for catheter, robotic ...

Multiobjective Codesign Optimization of a Planar Pneumatic Artificial Muscle‐Based Snake‐Like Robot for Enhanced Agility and Energy Efficiency

Advanced Robotics Research, EarlyView.
A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...
