A Multicenter, Randomized, Double-blind, and Placebo-parallel Controlled Trial of Tibetan Medicine Ruyi Zhenbaowan in Treatment of Knee Osteoarthritis增强出版
This study aimed to evaluate the clinical efficacy of Ruyi Zhenbaowan(RYZBW)in the treatment of initial and early knee osteoarthritis (KOA) through a prospective multicenter,randomized,double-blind,and placebo-parallel controlled trial.
Method
2
From October 13
th
, 2021 to December 25
th
, 2021, 240 KOA subjects meeting the acceptance criteria were enrolled in 15 sub-centers including Wangjing Hospital, Chinese Academy of Chinese Medical Sciences, and they were randomly divided into observation group and control group, with 120
cases in each group. The intervention measures for the observation group were RYZBW + health education, and the intervention measures for the control group were RYZBW placebo + health education. The intervention period in both groups was four weeks, and they were followed up for four weeks after the intervention. The primary outcome measure was the total score of Western Ontario and McMaster University Osteoarthritis Index score (WOMAC score), and the secondary outcome measures were the response rate of visual scale (VAS) pain score, WOMAC sub item scores (joint pain, joint stiffness, and joint function), quality of life (SF-12) score, and traditional Chinese medicine (TCM) syndrome score.
Result
2
(1) Efficacy evaluation. The marginal model results showed that the observation group was better than the control group in improving the WOMAC total score and WOMAC pain score in the treatment of KOA with RYZBW, and the difference was statistically significant (
P
<
0.05). There was no significant difference between the two groups in improving VAS score response rate, WOMAC function score, WOMAC stiffness score, SF12-PCS (quality of life-physical health) score, SF12-MCS (quality of life-mental health) score, and TCM syndrome score. (2) Subgroup analysis. ① In terms of VAS score response rate, the response rate of the observation group was higher than that of the control group for subjects with baseline VAS score of (4, 5], and the difference was statistically significant (
P
<
0.05). ② In terms of TCM syndrome score, for subjects aged [56, 60] and [61, 65], the decrease in total TCM syndrome score in the observation group was better than that in the control group, and the difference was statistically significant (
P
<
0.05).
Conclusion
2
Tibetan medicine RYZBW has good clinical efficacy in improving WOMAC total score, VAS score response rate, WOMAC pain score, WOMAC function score, and TCM syndrome score for patients with initial and early KOA, which can fill the lack of Tibetan medicine RYZBW in the treatment of KOA and make a demonstration study for the inheritance and development of ethnic medicine.
