刃针松解法治疗KOA的临床疗效及对生物力学指标的影响

Clinical efficacy of cutting edge needle for treating KOA and its effect on biomechanical indexes

目的探讨刃针松解法治疗膝关节骨性关节炎(KOA)的临床疗效及对生物力学指标的影响。方法选择2016年3-12月在江西省赣州市中医院确诊的KOA患者38例,依据患者接受的治疗方法,分为针刺组(采用传统针刺法)和刃针组(采用圆形刃针松懈法),每组19例。观察治疗过程中每组患者的疼痛情况,治疗3周后患者膝关节功能、炎性作用及生物力学指标情况。结果刃针组患者的总有效率为94.74%,高于针刺组的68.42%,两组比较差异有统计学意义(P<0.05)。治疗前两组患者视觉模拟评分法(VAS)及Tegner评分比较,差异无统计学意义(P>0.05);两组患者治疗后组内、差值及组间的VAS、Tegner评分比较,差异有统计学意义(P<0.05)。治疗后,两组患者股骨角(F)、关节间隙角(JS)、股骨内外髁高(H)/宽(W)值比较,差异有统计学意义(P<0.05),而胫骨角(T)、股骨胫骨角(FT)比较,差异无统计学意义(P>0.05)。结论刃针松解法治疗KOA的临床疗效突出,VAS、Tegner评分及生物力学指标均明显改善,值得临床推广。

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.
