Programmable Variable‐Stiffness Multilayer Elastomer Composites With High‐Aspect‐Ratio Low‐Melting‐Point Alloy Inclusions

Advanced Materials Technologies, EarlyView.
High‐aspect‐ratio low‐melting‐point alloy inclusions are embedded within multilayer silicone laminates to create thermally programmable stiffness. Sequential activation of alloy‐rich layers produces four distinct mechanical states and reconfigures tendon‐driven actuator trajectories under the same load.

Biomechanical Comparison of the Long Head of the Biceps Tendon Versus Conjoint Tendon Transfer in a Bone Loss Shoulder Instability Model

Orthopaedic Journal of Sports Medicine, 2019
Background: Augmentation of Bankart repair with long head of the biceps tendon transfer has been previously described, although there is a paucity of literature describing its biomechanical effects.

Pectoralis Major Muscle Rupture Repair: Technique Using Unicortical Buttons

Arthroscopy Techniques, 2012
Over the past few decades, there has been increased awareness of pectoralis major muscle injuries necessitating further evaluation of management options and, in particular, surgical repair. Injury typically occurs when an eccentric load is applied to the

Reconstruction of large chronic rotator cuff tear can benefit from the bone–tendon composite autograft to restore the native bone–tendon interface

Journal of Orthopaedic Translation, 2020
Purpose: We designed a paired controlled study to investigate the advantages of using bone–tendon composite autograft to reconstruct chronic rotator cuff tear compared with primary repair and provide some evidence to use the bone–tendon composite ...

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.

Spatial Stiffness Programming in Single‐Filament Material Extrusion Through Data‐Driven Thermal Foaming

Advanced Materials Technologies, EarlyView.
Single‐filament material extrusion enables spatial stiffness programming through locally controlled thermal foaming of TPU. A data‐driven G‐code framework tunes porosity from 15.7% to 40.7% and hardness from 90 to 63 Shore A within and across layers. Monolithic hands and soft actuators consequently achieve distinct programmed motions without material ...

Comparison of Tendon Lengthening with Traditional vs. Accelerated Rehab Following Achilles Tendon Repair: A Randomized Controlled Trial

Orthopaedic Journal of Sports Medicine, 2019
Objectives: Operative repair of Achilles tendon ruptures have shown successful outcomes. However, little is know about the amount of tendon or repair site lengthening after repair and if lengthening is affected by rehab protocols.

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.

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 ...

Dynamic changes of molecular pattern and cellular subpopulation in puncture-induced tendon injury model

iScience
Summary: Tendon degeneration and injury often result in significant pain and functional impairment. Typically, tendon healing occurs through a scar-mediated response and may progress to chronic tendinopathy without timely intervention.
