Rotator cuff tendinopathy: immunohistochemical changes across the spectrum of pathology.

The tissue changes associated with spectrum of rotator cuff tendinopathy are poorly understood. The aim of this study was to describe the tissue characteristics of the onset and progression of rotator cuff tendinopathy by using a novel, ultrasound-guided biopsy technique to obtain tissue samples from the supraspinatus tendon in several accurately phenotyped groups representing the spectrum of rotator cuff tendinopathy from normal, healthy tissue through to patients with a full thickness tear of the supraspinatus tendon.
