Abstract：BACKGROUND:Current treatment strategies for chronic non-healing wounds have shown unsatisfactory results,necessitating the exploration of novel therapeutic approaches.Concentrated growth factors,rich in high-concentration growth factors and possessing a stable natural three-dimensional structure,have demonstrated significant application value in the treatment of chronic non-healing wounds. OBJECTIVE:To review the current status of concentrated growth factor application in chronic non-healing wounds,analyze the shortcomings of concentrated growth factor in clinical applications,and propose constructive suggestions and prospects. METHODS:CNKI,WanFang,and VIP databases were searched with the key words of"concentrated growth factor,platelet concentrate products,chronic wound,chronic ulcer,wound healing,platelet-rich plasma,platelet-rich fibrin"in Chinese.PubMed was searched with the key words of"CGF,concentrated growth factor,platelet concentrate products,chronic wound,chronic ulcer,wound healing,PRP,PRF,platelet-rich plasma,platelet-rich fibrin"in English.The articles published from 2000 to 2024 were searched and further analyzed and summarized after screening. RESULTS AND CONCLUSION:Concentrated growth factor,with its diverse application forms,high concentration of growth factors,natural three-dimensional structure,compatibility with various material technologies,relatively low cost,and ease of operation,has demonstrated significant clinical value in the treatment of chronic wounds.Numerous researchers have validated its positive effects in chronic wound therapy through clinical applications.However,there is currently no clear consensus on standardized concentrated growth factor application protocols,and certain deficiencies have been revealed in practical applications,including issues with dosage,centrifugation settngs,identification schemes,and preparation methods for different forms of concentrated growth factor.There is substantial room for research on concentrated growth factor,and it is believed that with a clear consensus on its application in the future,concentrated growth factor could play a significant role in clinical practice.
