- Abstract: BACKGROUND:The reduction of contact area,edge load,and stress increase of adjacent cartilage caused by knee cartilage defect are considered to easily cause degenerative changes in this tissue,which may develop into knee osteoarthritis.Growth factors are considered to be a treatment method to promote the healing of damaged cartilage and delay the progression of degenerative arthritis.OBJECTIVE:To analyze the hotspots and prospects of growth factor-promoted knee cartilage regeneration research by bibliometric methods.METHODS:The first author retrieved 321 articles related to growth factor-promoted knee cartilage regeneration research from the Web of Science core set database.VOSviewer 1.6.19 software was used to analyze the publication volume,country,institution,keyword,and literature citation status of the articles,and investigate the research hotspots.RESULTS AND CONCLUSION:(1)From 2000 to 2024,the annual number of publications in the field of growth factor-promoted knee cartilage regeneration showed an overall upward trend,with the highest number of publications in 2021.Harvard University in the United States published the most papers.(2)Keyword analysis showed that the frequency of keywords such as growth factor,cartilage,cartilage repair,platelet-rich plasma,and cartilage regeneration was high.In addition,the keyword co-occurrence network diagram showed that growth factor was closely related to keywords such as cartilage repair and cartilage regeneration,indicating that growth factor research plays an important role in the field of cartilage regeneration.(3)The results of literature citation analysis showed that the combination of platelet-rich plasma and muscle-derived stem cells may provide a new and effective treatment strategy for patients with osteoarthritis,which can deepen the understanding of cartilage repair mechanisms by promoting stem cell proliferation and cartilage formation.Fibroblast growth factor 2,fibroblast growth factor 18,and insulin growth factor 1 play a key role in cartilage repair and can promote chondrocyte proliferation and matrix synthesis.In particular,fibroblast growth factor 18 can promote the repair of damaged cartilage,thereby alleviating patients'pain and dysfunction,which deserves further in-depth study in the future.The latest research has developed a new Polyhedrin Delivery System(PODS)that can continuously release growth factors such as bone morphogenetic protein 2 and 7,significantly promoting chondrocyte proliferation and cartilage repair.This system provides a new perspective and potential therapy for the treatment of osteoarthritis.(4)Therefore,bone morphogenetic protein 2,7,insulin growth factor 1,and recombinant human fibroblast growth factor 18 are promising growth factor therapies for promoting cartilage regeneration.In the future,further in-depth research on the mechanism of action of growth factors,optimization of treatment strategies,and strengthening of long-term efficacy and safety evaluation are needed.
