Fig. 6: Gross image of the rotator cuff and ultrasound image of target muscles at 12 W.

a1 Gross image of the rotator cuff injury area at 12 W. a2 Texture on each longitudinal section of the infraspinatus muscle. b, c Texture analysis parameters angular second moment (ASM) and inverse difference moment (IDM) of the infraspinatus muscle at 12 W (n = 4). d Overall score of degree of subdeltoid adhesion at the repair site at 12 W (n = 5). n.s. P > 0.05, *P < 0.05, **P < 0.01. All the error bars above are defined as standard deviation. Statistical methods, One-way analysis of variance with Tukey’s multiple-comparison test in (b, c) and Kruskal–Wallis test in (d).
