RESUMEN
Objective To observe the clinical efficacy of oral use of Bushen Huoxue Recipe (BHR) and steam washing with Shujin Waixi Granules for the treatment of knee osteoarthritis (KOA) with kidney deficiency and blood stasis. Methods One hundred and twenty KOA patients with kidney deficiency and blood stasis were divided into western medicine group, combination group and BHR group, 40 cases in each group. Western medicine group was treated with oral use of Diclofenac Sodium Sustained-release Tablets, combination group was treated with oral use of BHR and steam washing with Shujin Waixi Granules, and BHR group was given BHR orally alone. Western Ontario and McMaster Universities (WOMAC) osteoarthritis index and knee osteoarthritis severity index (ISOA) were used to evaluate the clinical efficacy of patients after treatment for 4 weeks. Results (1) After treatment, the scores of WOMAC osteoarthritis index and ISOA in the three groups were decreased(P< 0.01 compared with those before treatment), and the decrease in the combination group was superior to that in the western medicine group and BHR group(P< 0.05).(2) After treatment for 4 weeks, the total effective rate of western medicine group, combination group and BHR group was 82.5％, 95.0％, 80.0％ respectively, and the combination group had the strongest effect (P < 0.05). Conclusion Oral use of BHR combined with steam washing with Shujin Waixi Granules is effective for the treatment of KOA patients with kidney deficiency and blood stasis by relieving local pain and improving knee joint function.
