This study aimed to explore the mechanism of Modified Danggui Sini Decoction in the treatment of knee osteoarthritis via a combination of network pharmacology and molecular docking. Methods. The main chemical components and corresponding targets of Modified Danggui Sini Decoction were searched and screened in TCMSP database. The disease targets of knee osteoarthritis were summarized in GeneCards, OMIM, PharmGkb, TTD, and DrugBank databases. The visual interactive network of \u201cdrugs-active components-disease targets\u201d was drawn by Cytoscape 3.8.1 software. The protein-protein interaction network was constructed by STRING database. Then, GO function and KEGG pathway enrichment were analyzed by Bioconductor\/R, and the pathway of the highest degree of correlation with knee osteoarthritis was selected for specific analysis. Finally, molecular docking was used to screen and verify core genes by AutoDockTools software. Results. Seventy-one main components of Modified Danggui Sini Decoction and 116 potential therapeutic targets of knee osteoarthritis were selected. The KEGG pathway and the GO function enrichment analysis showed that the targets of Modified Danggui Sini Decoction in the treatment of knee osteoarthritis were mainly concentrated on PI3K-Akt signaling pathway, TNF signaling pathway, IL-17 signaling pathway, apoptosis signaling pathway, Toll-like receptor signaling pathway, Th17 cell differentiation signaling pathway, HIF-1 signaling pathway, and NF-\u03baB signaling pathway. It mainly involved inflammatory reaction, regulation of apoptotic signaling pathway, cellular response to regulation of inflammatory response, cellular response to oxidative stress, and other biological processes. The molecular docking results showed that ESR1-wogonin, MAPK1-quercetin, RELA-wogonin, RELA-baicalein, TP53-baicalein, TP53-quercetin, and RELA-quercetin have strong docking activities. Conclusion. Modified Danggui Sini Decoction has the hierarchical network characteristics of \u201cmulticomponent, multitarget, multifunction, and multipathway\u201d in the treatment of knee osteoarthritis. It mainly regulates the proliferation and apoptosis of chondrocytes by regulating the PI3K-Akt signaling pathway and establishes cross-talk with many downstream inflammatory-related pathways to reduce the overall inflammatory response. Meanwhile, HIF-1 expression was used to ensure the normal function and metabolism of knee joint under hypoxia condition, and the above processes play a key role in the treatment of knee osteoarthritis.<\/jats:p>","DOI":"10.1155\/2021\/6680637","type":"journal-article","created":{"date-parts":[[2021,2,14]],"date-time":"2021-02-14T04:41:20Z","timestamp":1613277680000},"page":"1-11","source":"Crossref","is-referenced-by-count":42,"title":["Mechanism of Modified Danggui Sini Decoction for Knee Osteoarthritis Based on Network Pharmacology and Molecular Docking"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3210-9791","authenticated-orcid":true,"given":"Chaoqun","family":"Feng","sequence":"first","affiliation":[{"name":"Department of Orthopedics, Hospital of Chengdu University of Traditional Chinese Medicine, Chengdu 610075, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Min","family":"Zhao","sequence":"additional","affiliation":[{"name":"Chengdu University of Traditional Chinese Medicine, Chengdu 610075, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leiming","family":"Jiang","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Hospital of Chengdu University of Traditional Chinese Medicine, Chengdu 610075, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ziang","family":"Hu","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Hospital of Chengdu University of Traditional Chinese Medicine, Chengdu 610075, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7313-139X","authenticated-orcid":true,"given":"Xiaohong","family":"Fan","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Hospital of Chengdu University of Traditional Chinese Medicine, Chengdu 610075, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.2460\/javma.236.1.67"},{"issue":"3-4","key":"2","doi-asserted-by":"crossref","first-page":"840","DOI":"10.1089\/ten.tea.2014.0375","article-title":"Collagen VI enhances cartilage tissue generation by stimulating chondrocyte proliferation","volume":"21","author":"S.
