This molecular study characterizes the inflammatory mediator profile of the subacromial bursa in rotator cuff disease, using microarray gene expression analysis and immunohistochemistry on bursal biopsies to determine whether subacromial bursitis represents a true inflammatory process and which specific molecules are involved.
When a patient with rotator cuff disease fails conservative management, this molecular evidence supports both pharmacologic anti-inflammatory treatment (NSAIDs, corticosteroids targeting COX and cytokine pathways) and subacromial bursectomy as an active therapeutic step — not merely incidental tissue removal — given that the bursa is confirmed as a significant source of inflammatory mediators including MMPs capable of ongoing tissue degradation.
