Association Between Tendon-related Transcription Factor and Ultrasound Images and Shoulder Function

November 20, 2020 updated by: National Taiwan University Hospital
The purpose of this project is to extract effusions and damaged tendons during tendon repair therapy in patients with tendon tears. Then, we would analyze tendon-related transcription factors from histology and cytology, and compare changes in tendon with ultrasound images. Helps to understand the mechanism of tendon lesions.

Detailed Description

According to past studies, it is often observed that changes in extracellular matrix, growth factors, and cytokines in degenerative tendons, indicating that the tendon is constantly changing. This change will in turn produce a change in the morphology of the tendon tissue in the ultrasound image. However, there have been few studies in the past literature on the correlation between constant changes in tendon-specific transcription factors and characterization on clinical ultrasound images. Therefore, the purpose of this project is to extract the effusion and damaged tendon while performing tendon repair therapy in patients with tendon tears, and to analyze the tendon-related transcription factors from histology and cytology to understand the changes in tendon homeostasis. At the same time, the interpretation of clinical ultrasound images was combined to establish the relationship between the biochemical factors of the cell tissues of chronic tendon lesions and the clinical ultrasound image. This study will help us to understand the mechanism of chronic tendinopathy.
