Abstract:Objective To explore the application effect of Duhuo Jisheng Decoction combined with sodium hyaluronate intra-articular injection in patients with knee osteoarthritis (KOA) of the liver and kidney deficiency type.Methods A total of 60 patients with KOA of the liver and kidney deficiency type admitted to our hospital from April 2023 to April 2025 were retrospectively selected as subjects and divided into two groups according to the treatment method: the single therapy group (n = 30) and the combination group (n = 30). The single therapy group received sodium hyaluronate intra-articular injection, while the combination group received Duhuo Jisheng Decoction in addition to the treatment given to the single therapy group. Clinical efficacy, Traditional Chinese Medicine (TCM) syndrome scores, knee joint function, Visual Analog Scale (VAS) scores, and inflammatory factors were compared between the two groups.Results The total effective rate of clinical efficacy in the combination group was higher than that in the single therapy group (P < 0.05). After treatment, the TCM syndrome scores in the combination group were lower than those in the single therapy group (P < 0.05). The Lysholm Knee Scoring Scale (Lysholm) and Hospital for Special Surgery knee score (HSS) were higher, while the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) was lower in the combination group than in the single therapy group (P < 0.05). At 3 and 5 weeks after treatment, the VAS scores in the combination group were lower than those in the single therapy group (P < 0.05). After treatment, the levels of C-reactive protein (CRP), interleukin-17 (IL-17), and interleukin-8 (IL-8) in the combination group were lower than those in the single therapy group (P < 0.05).Conclusion The application of Duhuo Jisheng Decoction combined with sodium hyaluronate intra-articular injection shows a significant effect in treating KOA of the liver and kidney deficiency type.
