The rate of rotator cuff injury repair and retear is high in elderly patients due to the combination of different degrees of osteoporosis. To solve this problem, many surgeons try to reduce retear rate of rotator cuff injuries in these patients by increasing the initial fixation strength of anchors and changing local bone conditions. The rapid advances of tissue engineering have made it possible to use growth factors as an aid. However, repair of rotator cuff injury with osteoporosis is still a great challenge for clinical workers. How to better increase anchor fixation strength, improve micro-environment of tendon and bone healing, reduce the rotator cuff retear rate have become the research focus in recent years. The paper reviewed literatures on the relationshipbetween osteoporosis and rotator cuff injury, effect of osteoporosis in rotator cuff tendon healing, methods of reducing osteoporosis on rotator cuff tendon healing, in order to guide clinical treatment, improve operative effect and postoperative satisfaction.
