Objective: To explore the clinical intervention effect of applying Huoxue Jiangu Decoction in the treatment of patients with osteoarthritis. Methods: Research work was carried out in our hospital from December 2018 to December 2019. A total of 100 patients with osteoarthritis received treatment during this period were selected and divided into two groups using random number method. One group was given sodium hyaluronate injection for treatment, which was the control group, and the other group was given Huoxuejiangu Decoction combined with sodium hyaluronate injection, which was the experimental group. The clinical treatment of the two groups of patients was compared and analyzed. Results: The patients' pain levels were compared. There was no significant difference between the groups before the intervention treatment. After treatment, the experimental group score was (3.05±0.55), which was lower than the control group, the improvement effect was more significant, and the difference between the groups was significant (P< 0.05), the experimental group had a better effect. The clinical treatment of the two groups of patients was compared and analyzed. There was no significant difference in the WOMAS index between the two groups before treatment. After treatment, the score of the experimental group was (34.33±6.98), and the improvement rate was (37.45±13.22). After treatment, the score was lower and the improvement rate was higher, which was significantly higher than the control group (P <0.05), which was significant. The treatment effective rate of the patients in the experimental group was 80.00%, and the treatment effective rate of the patients in the control group was 64.00%. When comparing, the effective rate of the experimental group was higher, and the data comparison between the groups was significantly different. Conclusion: For the patients with osteoarthritis, the application of Huoxue Jiangu Decoction has a significant clinical effect, which can reduce the patient's pain level, improve the patient's clinical symptoms, have high clinical value, and it can be promoted.
