Background: Cold-dampness-type knee osteoarthritis is a common middle-aged and elderly disease, but its pathogenesis is not fully understood, and its clinical treatment has limitations. Glucosamine sulfate capsules are commonly used for treating arthritis, and San Bi Tang is a classic formula of traditional Chinese medicine (TCM) that has the effects of warming yang, dispelling dampness, relaxing muscles, and activating collaterals. This research hypothesized that the combination of modified San Bi Tang and glucosamine sulfate capsules could enhance the clinical efficacy of treating cold-dampness-type knee osteoarthritis through complementary effects.
Aim: To analyze the clinical efficacy of San Bi Tang combined with glucosamine sulfate capsules when treating cold-dampness-type knee osteoarthritis.
Methods: A total of 110 patients with cold-dampness-type knee osteoarthritis were selected as research subjects and randomly divided into a control group and an experimental group of 55 cases each. The control group received only treatment with glucosamine sulfate capsules, while the experimental group received additional treatment with modified San Bi Tang for a duration of 5 wk. The patients' knee joint functions, liver and kidney function indicators, adverse reactions, and vital signs were evaluated and analyzed using SPSS 26.0 software.
Results: Before treatment, the two groups' genders, ages, and scores were not significantly different, indicating comparability. Both groups' scores improved after treatment, which could indicate pain and knee joint function improvement, but the test group had better scores. The TCM-specific symptoms and the clinical efficacy of the treatment in the test group were higher. Before and after treatment, there were no abnormalities in the patients' liver and kidney function indicators.
Conclusion: The combination of modified San Bi Tang and glucosamine sulfate capsules is superior to treatment with sulfated glucosamine alone and has high safety.
