(A) Representative trichrome straining of supraspinatus (SS) and deltoid (DL) biopsy specimens. (B) There was a higher percentage of collagen staining in the full-thickness tears compared with the partial tear and DL. (C) Oil Red O evaluation of fatty infiltration (FI) of full-thickness and partial-thickness tears in the SS compared with the control DL. (D) Quantification of FI with significantly more fat in the full-thickness than the partial-thickness tears. (E) Typical immunostaining of full-thickness tears compared with partial tears. Green stains are laminin and red is stained for fibroadipogenic progenitors. *P < .05.
