RESUMO
<p><b>OBJECTIVE</b>To compare the difference in the efficacy on osteoarthritis of the knee between the ultrastructural acupotomy therapy at the counter-Ashi points and the conventional acupuncture-moxibustion therapy.</p><p><b>METHODS</b>Sixty cases were randomly devided into an ultrastructural acupotomy therapy group (group A) and a conventional acupuncture-moxibustion group (group B), 30 cases in each one. In the group A, the ultrastructural acupotomy therapy was applied to the counter-Ashi points in which pain was alleviated or disappeared on pressure. The treatment was given once a week, lasting for 1 month. In the group B, the acupuncture-moxibustion therapy was applied to Dubi (ST 35), Neixiyan (EX-LE 4), Zusanli (ST 36), Yanglingquan (GB 34), etc. The treatment was given once daily, lasting for 1 month. Before and after treatment, the Visual Analogue Scale (VAS), Lysholm knee joint scale and the affected knee joint flexion angle were observed in the two groups. The clinical efficacy was compared between the two groups.</p><p><b>RESULTS</b>After treatment, the scores of VAS, Lysholm knee joint scale and the affected knee joint flexion angle were improved obviously as compared with those before treatment in either group (P < 0.01, P < 0.05). The results of them in the group A were superior apparently to those in the group B (all P < 0.05). The total effective rate in the group A was superior to that in the group B [80.0% (24/30) vs 60.0% (18/30), P < 0.05].</p><p><b>CONCLUSION</b>The ultrastructural acupotomy therapy at the counter-Ashi points achieves the superior clinical efficacy on osteoarthritis of the knee as compared with the conventional acupuncture therapy. It relieves pain and improves the motion range of knee joint effectively. It is simple in operation and less in treatment frequency.</p>
