[Effect of acupoint application of Zhanjin Huoxue formula combined with local cold compress on swelling and pain after knee arthroscopy in patients with knee osteoarthritis].

To compare the effect between acupoint application of Zhanjin Huoxue formula combined with local cold compress and simple local cold compress on swelling and pain after knee arthroscopy in patients with knee osteoarthritis (KOA).A total of 62 KOA patients with knee swelling after knee arthroscopy were randomly divided into an observation group and a control group, 31 cases in each group. In the control group, cold compress was adopted after surgery, 3 times a day. On the basis of the treatment as the control group, acupoint application of Zhanjin Huoxue formula (angelicae sinensis radix, chuanxiong rhizome, cinnamon twig, poria, etc.) was applied at Liangqiu (ST 34), Xuehai (SP 10), Zusanli (ST 36), Fenglong (ST 40), Sanyinjiao (SP 6), Yinlingquan (SP 9), Yanglingquan (GB 34), Xuanzhong (GB 39) on the affected side in the observation group, 4 h each time, 2 times a day. The treatment was given 7 days in both groups. Before treatment and 1,3,5 and 7 days into treatment, the pain visual analogue scale (VAS) score and swelling value of knee joint (2 cm above the patella upper pole, patella midline, 5 cm below the patella lower pole) were compared in the two groups.The VAS scores 3, 5 and 7 days into treatment were lower than those before treatment in the two groups (P<0.05), and those in the observation group were lower than the control group (P<0.05). The swelling values of 2 cm above the patella upper pole 3, 5 and 7 days into treatment were lower those before treatment in the two groups (P<0.05), and those in the observation group were lower than the control group (P<0.05). The swelling values of patella midline 1, 3, 5 and 7 days into treatment were lower than those before treatment in the two groups (P<0.05), and except for 1 day into treatment, those in the observation group were lower than the control group (P<0.05). The swelling values of 5 cm below the patella lower pole 1 day into treatment in the observation group and 3, 5 and 7 days into treatment in the two groups were lower those before treatment (P<0.05), and except for 1 day into treatment, those in the observation group were lower than the control group (P<0.05). The total effective rate in the observation group was 93.5% (29/31), which was higher than 74.2% (23/31) in the control group (P<0.05).Acupoint application of Zhanjin Huoxue formula combined with cold compress could effectively improve the knee joint swelling and pain after arthroscopy in KOA patients, and the curative effect is better than simple cold compress.目的：比较展筋活血方穴位贴敷联合局部冷敷与单纯局部冷敷对膝骨关节炎（KOA）患者膝关节镜术后肿胀、疼痛的影响。方法：将62例膝关节镜术后伴有膝关节肿胀的KOA患者随机分为观察组和对照组，每组31例。对照组于术后采用冰袋冷敷治疗，每日3次；观察组在对照组的基础上选取展筋活血方（当归、川芎、桂枝、茯苓等）进行穴位贴敷，穴取患侧梁丘、血海、足三里、丰隆、三阴交、阴陵泉、阳陵泉、悬钟，每次4 h，每日2次，两组均治疗7 d。比较两组治疗前和治疗第1、3、5、7天后疼痛视觉模拟量表（VAS）评分和膝关节（髌骨上极上2 cm、髌骨中线和髌骨下极下5 cm）肿胀值，并观察疗效。结果：治疗第3、5、7天，两组患者VAS评分均较治疗前降低（P<0.05），且观察组低于对照组（P<0.05）。治疗第3、5、7天，两组患者髌骨上极上2 cm肿胀值均较治疗前降低（P<0.05），且观察组低于对照组（P<0.05）。治疗第1、3、5、7天，两组患者髌骨中线肿胀值均较治疗前降低（P<0.05），且除治疗第1天外，观察组均低于对照组（P<0.05）。观察组治疗第1天及两组治疗第3、5、7天髌骨下极下5 cm肿胀值均较治疗前降低（P<0.05），且除治疗第1天外，观察组均低于对照组（P<0.05）。观察组总有效率为93.5%（29/31），高于对照组的74.2%（23/31，P<0.05）。结论：展筋活血方穴位贴敷联合冷敷能有效改善KOA患者膝关节镜术后关节肿胀、疼痛，疗效优于单纯冷敷治疗。.
