Abstract: BACKGROUND: Studies have shown that microRNAs play an important role in the regulation of inflammation-mediated diseases. miRNAs are involved in a series of processes such as cell differentiation, apoptosis, proliferation, fat metabolism, inflammation, and immune response.
OBJECTIVE: To review the roles of microRNAs in the occurrence and development of osteoarthritis from the pathogenesis of osteoarthritis and the relationship between microRNAs and pain, aging, early diagnosis and treatment, so as to provide new ideas for the diagnosis, prevention and treatment of osteoarthritis.
METHODS: CNKI, VIP, WanFang, PubMed, Biosos Preview and Web of Science were searched for relevant literatures published from 1990 to 2020. The search terms were “Osteoarthritis; miRNAs; Chondrocytes; Gene therapy” in Chinese and English, respectively. After excluding repetitive and obsolete literatures, 76 literatures meeting the inclusion criteria were finally selected.    
RESULTS AND CONCLUSION: MicroRNA is a kind of non-coding protein small molecule RNA, which widely exists in various eukaryotic cells. MicroRNA is widely involved in the regulation of post-transcriptional genes, affects biological processes and cellular signal transduction due to its binding to target genes, and plays a very important role in the development of osteoarthritis. MicroRNAs participate in the regulation of post-transcriptional genes, affects cellular signal transduction and biological processes by binding to target genes, and plays an important regulatory role in the occurrence and development of osteoarthritis. Although the role of microRNAs in osteoarthritis has been studied a lot, the specific mechanism is still unclear.
