Testosterone replacement therapy is associated with increased odds of Achilles tendon injury and subsequent surgery: a matched retrospective analysis

Journal of Foot and Ankle Research, 2023
Background Prescription of testosterone replacement therapy (TRT) has increased in the United States in recent years, and though anabolic steroids have been associated with tendon rupture, there is a paucity of literature evaluating the risk of Achilles ...

Achilles Tendon Resting Angle Relates to Tendon Length and Function

Foot & ankle international, 2018
Background: Following Achilles tendon rupture, tendon elongation leads to long term deficits in calf function. A surrogate measure of Achilles tendon length, Achilles tendon resting angle (ATRA), has been described but has not been validated against ...

The Free Achilles Tendon Is Shorter, Stiffer, Has Larger Cross-Sectional Area and Longer T2* Relaxation Time in Trained Middle-Distance Runners Compared to Healthy Controls

Frontiers in Physiology, 2020
Tendon geometry and tissue properties are important determinants of tendon function and injury risk and are altered in response to ageing, disease, and physical activity levels.

Monitoring Achilles tendon healing progress in ultrasound imaging with convolutional neural networks [PDF]

, 2019
Achilles tendon rupture is a debilitating injury, which is typically treated with surgical repair and long-term rehabilitation. The recovery, however, is protracted and often incomplete. Diagnosis, as well as healing progress assessment, are largely based on ultrasound and magnetic resonance imaging.

Ultrashort Echo Time Magnetic Resonance Fingerprinting (UTE-MRF) for Simultaneous Quantification of Long and Ultrashort T2 Tissues [PDF]

Magnetic Resonance in Medicine (2019), 2018
Purpose: To demonstrate an ultrashort echo time magnetic resonance fingerprinting (UTE-MRF) method that can simultaneously quantify tissue relaxometries for muscle and bone in musculoskeletal systems and tissue components in brain and therefore can synthesize pseudo-CT images.

Power to the springs: Passive elements are sufficient to drive push-off in human walking [PDF]

arXiv, 2022
For the impulsive ankle push-off (APO) observed in human walking two muscle-tendon-units (MTUs) spanning the ankle joint play an important role: Gastrocnemius (GAS) and Soleus (SOL). GAS and SOL load the Achilles tendon to store elastic energy during stance followed by a rapid energy release during APO.

MRI of the Achilles tendon—A comprehensive pictorial review. Part one

European Journal of Radiology Open, 2021
The normal Achilles tendon is composed of twisted subtendons separated by thin high signal septae, which are a potential pitfall on MRI because they mimic a tendon tear.Tendinopathy and full thickness tears may be assessed effectively both on MRI and ...

Full-range optical imaging of planar collagen fiber orientation using polarized light microscopy [PDF]

arXiv, 2021
A novel method for automated assessment of directions of collagen fibers in soft tissues is presented. It is based on multiple rotated images obtained via polarized light microscope with perpendicular and inclined polarizers and thus it breaks the limitation of 90{\deg} periodicity of polarized light intensity and evaluates the fiber orientation over ...

Enhancing Tendon Regeneration: Investigating the Impact of Topography on the Secretome of Adipose‐Derived Stem Cells

Advanced Science, EarlyView.
The impact of topography on the secretome of adipose‐derived stem cells (ADSCs) has the potential for promoting tendon regeneration. The secretome generated from ADSCs on aligned structure has a potent effect in promoting cell migration, proliferation, tenogenic differentiation, macrophage M2 polarization, and tendon mechanical function recovery ...
