What this trial studies

This project aims to collect ultrasonic spectrum information from fibrotic tissue in the shoulder and knee joints. By utilizing machine learning, the study will investigate the mechanisms of ultrasound imaging of fibrosis and develop a model to establish the relationship between joint stiffness and fibrosis formation. The ultimate goal is to create a method for ultrasonic localization and evaluation of joint fibrosis, which could lead to new conservative treatment methods and improved surgical positioning. This research seeks to reduce the occurrence of joint fibrosis and enhance patient recovery and functionality.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 with unilateral shoulder or knee joint stiffness lasting more than three months.

Not a fit: Patients with non-healing wounds, joint dislocations, or other conditions that prevent ultrasound examination will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic and treatment methods for patients suffering from joint stiffness due to fibrosis.

How similar studies have performed: While this approach is innovative, similar studies utilizing ultrasound imaging for fibrotic tissue have shown promise in other contexts.
