Abstract:

BACKGROUND: Platelet-rich plasma has no significant impact on functional outcomes and repair integrity, but may be advantageous in small and medium tears of rotator cuff. Further studies should focus on leukocyte-rich versus poor preparations and the use of platelet-rich plasma in patients that are high risk for repair failure.

OBJECTIVE: To summarize the current status and progress of basic research and clinical trials on biologic adjuvants in the repair of rotator cuff, and to review the latest scientific findings.
METHODS: A computer-based search of PubMed, MedLine, and Springerlink databases was performed for relevant articles published from 2008 to 2018 with the keywords of “biological therapy, biotherapy, RCT, rotator cuff tear”. Initially, 168 articles were retrieved, and finally 32 eligible articles were included for result analysis.
RESULTS AND CONCLUSION: Biologic and synthetic patches or augments provide mechanical stability for large and massive rotator cuff tears and decrease re-tear rate. Mesenchymal stem cells can improve healing rate without an impact on outcomes. Cytokines and growth factors are promising in animal experiments, but need to be verified by clinical trials. In massive or revision repairs, allograft or synthetic patch augmentation should be considered. Platelet-rich plasma may be available for small tears. Further investigations are needed to evaluate the value of mesenchymal stem cells and various chemical signals.
