Observations on the Efficacy of Yang's Needle Tapping-cupping Bloodletting Method in Treating Knee Osteoarthritis

Objective To investigate the clinical efficacy of Yang's needle tapping-cupping bloodletting method in treating knee osteoarthritis. Methods Sixty patients with knee osteoarthritis were randomly allocated to treatment and control groups, 30 cases each. The treatment group received Yang's pricking-cupping bloodletting therapy and the control group, conventional acupuncture. The VAS pain scores and the knee osteoarthritis symptom and sign scores were compared between the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups. Results The total efficacy rate was 96.0% in the treatment group and 90.0% in the control group; there was a statistically significant difference between the two groups(P0.05). There were statistically significant pre-/post-treatment differences in the VAS pain score and the symptom and sign score in the two groups(P0.05). There was a statistically significant post-treatment difference in the symptom and sign score between the two groups(P0.05). Conclusion Yang's needle tapping-cupping bloodletting therapy is an effective way to treat knee osteoarthritis.
