Achilles tendon ruptures are traumatic injuries, and techniques for assessing repair
outcomes rely on patient-based measures of pain and function, which do not directly assess
tendon healing. Consequently, there is a need for a quantitative, in vivo measure of tendon
properties. Therefore, the purpose of this study was to validate ultrasound imaging for
evaluating collagen organization in tendons. In this study, we compared our novel, high-
frequency ultrasound (HFUS) imaging and analysis method to a standard measure of …

Achilles tendon ruptures are traumatic injuries that frequently occur in active individuals and
result in significant medical expense. Common techniques for assessing outcomes of
surgical repair and rehabilitation rely heavily on patient-based measures of pain and
function. While these measures can provide evidence for recovery of functional
performance, they do not directly assess tendon healing which, if insufficient, can lead to re-
rupture. The clinical evaluation of collagen organization following Achilles tendon injury may …
