Mitigation Of Inflammation In Early Post-Traumatic Osteoarthritis Through Low-Intensity Ultrasound, Shahid Khan

Dissertations

Post-traumatic osteoarthritis (PTOA), a subset of OA caused by direct injury or repetitive microtrauma, results in a robust release of inflammatory mediators. If inadequately controlled, this pro-inflammatory phase leads to early tissue damage. The biomedical burden of PTOA is significant and inadequately addressed due to difficulties in identifying the disease onset, slow progression, and incomplete understanding of its etiology and pathogenesis. However, PTOA's distinct initiating events allow for early intervention. This thesis investigates whether fibronectin fragments (FnFs) can induce an early inflammatory response in a triple cellular in vitro model of early PTOA and whether continuous low-intensity ultrasound (cLIUS) can …
