H&E staining of SS tendon and IS tendon (×100). SS and IS tendons were reattached to humeral head in the three repair groups, though more synovial tissue proliferation and scar tissue was found around the tendon in the three repair groups when compared with the sham group. Only scar tissue was seen between torn tendons and humeral head in the TT group. B, bone; I, interface; T, tendon; ST, scar tissue; S, suture.
