Abstract:

BACKGROUND: There is no effective treatment for partial rotator cuff tears, and platelet-rich plasma (PRP) is a promising therapy.
OBJECTIVE: To summarize the application status and progress of basic research and clinical trials addressing PRP injection in partial rotator cuff tear healing.
METHODS: A computer-based search of PubMed, MedLine, Springerlink databases was performed for relevant articles published from 2008 to 2018 with “PRP, platelet-rich plasma, partial RCT, partial rotator cuff tear” as key words. Initially, 74 articles were retrieved, and finally 12 eligible articles were included for result analysis.
RESULTS AND CONCLUSION: Few clinical trial or animal experiment addressing the present use of PRP injection in a partial rotator cuff tear are reported. There are more clinical trials about PRP applied in arthroscopic repair of full-thickness rotator cuff tear, but most of them do not show better outcomes than the control group. Some studies show that PRP injection applied in partial rotator cuff tear can obtain better outcomes than corticosteroid injection. The results of PRP injection in partial rotator cuff tear healing still need further investigation. The methods to prepare PRP are varied, whether PRP is injected to the precision site is also important. Further fundamental research and clinical studies are required to verify the method and the result of PRP injection in partial rotator cuff healing.
