Traditional Chinese medicine external treatment combined with sodium vitrate injection for the treatment of knee osteoarthritis: A meta-analysis.

Abstract

Osteoarthritis of the knee is a clinically common degenerative joint disease that has a high prevalence and, if left untreated, can seriously affect a patient's quality of life. The objective of this article is to systematically evaluate the efficacy and safety of the combination of traditional Chinese medicine external treatment with sodium vitrate injection in the treatment of osteoarthritis of the knee. By searching China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP), Wanfang Database (WF), Chinese Biomedical Literature Database (CBM), Embase, Pubmed, Cochrane Library. The search time was set from 2010 to March 2023. Revman 5.4 software was used for data analysis. The protocol was registered in the PROSPERO database (ref. CRD42023426707). A total of 3239 patients from 31 RCTs were finally included. Meta-analysis showed significant differences in the Total clinical Efficiency (mean difference (MD) = 4.62, 95% Confidence Interval (CI) = 3.52-6.08, P < .01), WOMAC score (MD = 6.57, 95% CI = 5.78-7.36, P < .01), VAS score (MD = 0.26, 95% CI = 0.14-0.37, P < .0001), Lysholm scores (MD = 5.21, 95% CI = 4.51-5.90, P < .0001), and Lequesne index (MD = 5.21, 95% CI = 4.51-5.90, P < .0001) between the Traditional Chinese Medicine External Treatment combined with sodium vitrate injection group and control group. The efficacy of traditional Chinese external treatment combined with sodium vitrate injection for osteoarthritis of the knee was superior to that of sodium vitrate injection only in all cases. Due to the limitations of the quantity and quality of the included literature, more high-quality literature is needed to validate this conclusion at a later stage.
