Rotator cuff tear

Rotator cuff tears are frequent shoulder problems that are usually dealt with by surgical repair. Despite improved surgical techniques, the tendon-to-bone healing rate is unsatisfactory due to difficulties in restoring the delicate transitional tissue between bone and tendon (Gomol et all., 2004; Valencia Mora et all., 2015). Although there is a lack of consensus as to whether the application of stem cells to enhance the rotator cuff healing is effective or not, some authors have developed different strategies for clinical application of the experimental findings.
