Rotator cuff injury, considered as a resource of pain, disability and dyssomnia to serious decline in the quality of life, is a common disorder of the shoulder joint. Basic principles of rotator cuff repair aim at achieving high initial ifxation strength, maintaining mechanical stability and restoring the anatomic healing of the cuff tendon. After the routine surgical procedure for rotator cuff repair, the biology and histology of the normal enthesis are not restored. Tendon-to-bone healing occurs with a ifbrovascular scar tissue interface that is mechanically inferior to the native insertion site, which may lead to high re-rupture rate. For these reasons, new approaches are required to improve structural healing. Tissue engineering strategies have been suggested to improve the biological environment around the bone-tendon interface and to promote regeneration of the native insertion site. Although experimental applications of growth factors and scaffolds on animal models demonstrate promising results, tech
