Clinical efficacy of cutting edge needle for treating KOA and its effect on biomechanical indexes / 重庆医学

ABSTRACT

Objective To investigate the clinical effect of cutting edge needle for treating knee osteoarthritis(KOA) and its effect on biomechanical indexes.Methods Thirty-eight patients with KOA diagnosed in the Ganzhou Municipal Hospital of Traditional Chinese Medicine from March 2016 to December 2016 were selected and divided into the acupuncture group(using traditional acupuncture method) and sham-acupuncture group(using round cutting edge needle method),19 cases in each group.The patient' s pain situation of each group during the treatment process,knee joint function,inflammatory effects and biomechanical indicators after 3-week treatment were observed.Results The total effective rate of the sham-acupuncture group was 94.74％,which was higher than 68.42％ in the acupuncture group,the difference between the two groups was statistically significant(P＜0.05).The visual analog scale(VAS) and Tegner scores before treatment had no statistical difference between the two groups(P＞0.05).The VAS and Tegner scores after treatment had statistical difference between the two groups(P＜0.05).After treatment,the differences of femoral angle(F),joint space angle(JS) and femoral condyle height(H)/width(W) between the two groups were statistically significant(P＜0.05),while the tibial angle(T) and femoral tibial angle(FT) had no statistically significant difference(P＞0.05).Conclusion The clinical efficacy of cutting edge needle in the treatment of KOA is prominent,and the VAS score,Tegner score and biomechanical indexes are significantly improved,which is worthy of clinical promotion.
