Regional histologic diﬀerences in the long head of the biceps tendon following subpectoral biceps tenodesis in patients with rotator cuﬀ tears and SLAP lesions
Prospectively enrolled patients undergoing an open subpectoral LHBT tenodesis in the setting of a rotator cuﬀ (RTC) tear or SLAP lesion. Perioperative data were collected and the excised LHBT was analyzed by a fellowship trained pathologist. Tendons were sectioned into proximal (biceps anchor), middle (bicipital groove), and distal (myotendinous junction) portions. Sections were stained with Movat’s pentachrome stain and digitized for analysis. Comparisons were made between the histologic ﬁndings present in the setting of a rotator cuﬀ tear with those seen in the setting of a SLAP tear.
