Summary

The purpose of this study is to utilize Shear Wave Elastography (SWE) to study the viscoelastic properties of tendons to understand the functional differences between normal/asymptomatic and symptomatic tendon states. The study will also assess the degree of tendon healing following standard of care treatment.

Detailed description

Tendinopathy is a common affliction in athletes, recreational exercisers, the general population and even inactive people. Tendon pathology presenting clinically is most commonly seen in the chronic state related to tendon degeneration manifested as intra-tendinous mucoid degeneration and chondroid metaplasia, which in many cases is accompanied by superimposed small intrasubstance/interstitial tears. Then a vicious cycle of attempted inadequate healing with superimposed acute pathology ensues leading to significant pain and discomfort over time significantly limiting physical activity. The exact pathogenesis of this disease has not been clarified scientifically. The first part of this study aims to establish the difference between asymptomatic and symptomatic tendons among patients affected by moderate-to-severe, chronic (\>6 months of symptoms) tendinopathy in comparison to asymptomatic patients. After establishing a range of elastography normal to severe pathologic measurements, a second part of the study will focus on utilizing ultrasound elastography imaging follow up to assess degree of tendon healing after various standard of care treatments. The purpose of this prospective observational study is to utilize a ultrasound modality known as real-time Shear Wave Elastography (SWE) to study the viscoelastic properties of tendons, such as the Achilles, patellar, quadriceps, epicondylar, and rotator cuff, to understand the functional differences between normal/asymptomatic (n=75) vs symptomatic (n=75) tendon states (total n=150). The secondary aim will be to assess the degree of tendon healing after standard of care treatment. The clinical implications are very significant because it will provide insights into the mechanism of tendon healing.

Conditions

• Tendinopathy

Interventions

Type	Name	Description
DEVICE	Shear Wave Elastography	An ultrasound (US) technique, known as shear wave elastography (SWE), is used to examine structure and biomechanical function. The examination takes place in the ultrasound room at the study site and lasts for approximately 20 minutes.
