Fig. 8From: Fixation technique of biodegradable magnesium alloy suture anchor in the rotator cuff repair of the shoulder in a goat model: a technical noteThe histological analysis of goat implanted with Ti suture anchor. a Periosteum connecting the detached tendon and bone. Note the discontinuous interface with adipose infiltration (black arrows), which might reduce the tensile strength compared with the healthy tissue. H&E stain, scale bar = 100 μm. b Masson trichrome staining indicated collagen secretion on Fig. 1A, and the amount of collagen (white arrows) was reduced. MT stain, scale bar = 100 μm. c Periosteum of the undetached tendon revealed robust and continuous interface between the tendon and bone (*). H&E stain, scale bar = 100 μm. d Healthy tendons exhibiting dense and uniform collagen on the periosteum. MT stain, scale bar = 100 μmBack to article page
