Abstract accepted for a poster presentation at the 2024 Madigan Research Day

Little is known about the pathobiology of unidirectional anterior and posterior shoulder instability. The purpose of this study was to compare gene expression differences in the peripheral blood and capsular tissue of young patients with recurrent anterior shoulder instability and those patients with unidirectional posterior shoulder instability.

There are significant gene expression differences in the shoulder capsule of anterior and posterior shoulder instability patients. This transcriptomic data may provide an improved understanding of the pathobiology of various forms of shoulder instability which could lead to future precision medicine approaches.
