OBJECTIVE@#To observe the effect on supplementary analgesia after total knee arthroplasty (TKA) treated with electroacupunture, and explore it's mechanism.@*METHODS@#A total of 40 patients with severe knee osteoarthritis were randomized into an observation group and a control group, 20 cases in each one. During the operation, patients were given epidural anesthesia in the two groups, conventional patient controlled epidural analgesia and oral celecoxib were applied after the operation. In the observation group, electroacupunture was used at Liangqiu (ST 34), Xuehai (SP 10), Yinlingquan (SP 9), Zusanli (ST 36), Fenglong (ST 40) and Qiuxu (GB 40) on the operation side from the 1st to 7th day after the operation to support analgesia, 30 min for each time, once a day. The visual analogue scale (VAS) was used to record postoperative pain of resting state and active state. The levels of serum prostaglandin E and β-endorphin were measured on the 1st and 7th day after surgery in the two groups.@*RESULTS@#In the observation group, the VAS scores of resting state and active state were superior to the control group on the 3rd, 5th and 7th day after the operaton (all <0.05); after the treatment, the level of serum β-endorphin was increased and the level of serum prostaglandin E was reduced in the two groups (all <0.05), and the change of the observation group was larger than that of the control group (both <0.05).@*CONCLUSION@#Electroacupunture has the effect of supplementary analgesia for patients after TKA, the mechanism may be related to promote the synthesis of β-endorphin and inhibit the synthesis of prostaglandin E.

OBJECTIVE@#To compare the therapeutic effect between thunder-fire moxibustion combined with external applicaion of powder and thunder-fire moxibustion alone for mild and moderate knee osteoarthritis.@*METHODS@#A total of 70 patients with mild and moderate knee osteoarthritis were randomly divided into an observation group and a control group, 35 cases in each group. In the observation group, thunder-fire moxibustion combined with external applicaion of powder were applied, Thunder-fire moxibustion was applied at Xuehai (SP 10), Liangqiu (ST 34), Neixiyan (EX-LE 4), Yanglingquan (GB 34) and point, external applicaion of powder was given to the affected knee after the treatment of thunder-fire moxibustion. Simple thunder-fire moxibustion was given in the control group. All patients in the two groups were treated once a day, 7 days as one course and the consecutive 4 courses were required, with an interval of 1 day between courses. Before and after treatment, the visual analogue scale (VAS) score and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score were used to assessed knee pain, stiffness and physical function in the two groups. In addition, the efficacy was evaluated.@*RESULTS@#Compared before treatment, the VAS scores, total scores of WOMAC, pain scores, stiffness scores and physical function scores were reduced after treatment in the two groups (<0.01), and the scores in the observation group were significantly lower than those in the control group (<0.01, <0.05). The total effective rate was 97.0% (32/33) in the observation group, which was superior to 91.2% (31/34) in the control group (<0.05).@*CONCLUSION@#Thunder-fire moxibustion combined with external applicaion of powder are superior to simple thunder-fire moxibustion in improving the symptoms and delaying the development of the disease for mild and moderate knee osteoarthritis.
