简要总结
Knee osteoarthritis(OA), also known as degenerative arthritis, have affected a lot of people. Patients with severe osteoarthritis frequently develop one or more of the typically following symptoms: joint pain, stiffness, activity with joint friction noise, limited mobility, such as difficulty walking and climbing. Now there are many western medicine treatments including symptom relief and joint cartilage protective agents for OA, but the results have not yet satisfied. TCM treatment of osteoarthritis has remarkable curative effect and unique advantage.Tong-Luo-Qu-Tong Plaster is a common method to treat osteoarthritis of the knee for thousands of years in China. It lacked a large sample randomised, double-blind, parallel positive controlled, multicenter clinical trial, and the clinical evidence of Tong-Luo-Qu-Tong Plaster for Knee Osteoarthritis need to be further completed.
详细描述
A randomised, double-blind, parallel positive controlled, multicenter clinical trial will be conducted to assess the effectiveness and safety of Tong-Luo-Qu-Tong Plaster on patients with knee osteoarthritis. A total of 2000 patients with knee osteoarthritis will be recruited and randomly allocated into experimental group(1500) or control group(500). Each patient will undergo a 2-week treatment with herbal patches for one session per day.The western Ontario and McMaster universities osteoarthritis index (WOMAC) as objective indicators of efficacy is the primary efficacy endpoint of the study.The secondary outcome measures are the changes in TCM syndrome quantitative score, Visual Analog Scale/Score (VAS) score of pain, and the effective time of pain relief of drug from the baseline to 1 week, 2 weeks' follow-up.
