[Effect of acupuncture on knee injury and osteoarthritis outcome score in patients with knee osteoarthritis].

To verify the clinical effect of acupuncture on knee osteoarthritis (KOA).Forty-two patients with KOA were randomly divided into an acupuncture group (21 cases, 1 case dropped off) and a sham acupuncture group (21 cases, 1 case dropped off). The patients in the acupuncture group were treated with routine acupuncture at 5-6 local acupoints [Dubi (ST 35), Neixiyan (EX-LE 4), Heding (EX-LE 2), Yinlingquan (SP 9), Xuehai (SP 10), Zusanli (ST 36), etc.] and 3-4 distal acupoints [Fengshi (GB 31), Waiqiu (GB 36), Xuanzhong (GB 39), Zulinqi (GB 41), etc.]. The patients in the sham acupuncture group were treated with shallow needling technique at non-acupoint. The needles were retained for 30 min in both groups. All the treatment was given three times a week for 8 weeks. Knee injury and osteoarthritis outcome score (KOOS) were recorded before and after treatment and 18-week follow-up.Compared before treatment, the scores of 5 dimensions of KOOS [pain, symptoms (except pain), daily activities, sports and entertainment, and quality of life] were increased after treatment and during follow-up in the two groups (P<0.05), and the scores of pain and daily activities in the acupuncture group were higher than those in the sham acupuncture group (P<0.05).Acupuncture can reduce the pain symptoms and improve daily activities in patients with KOA.目的：验证针刺治疗膝骨关节炎（KOA）的临床疗效。方法：将42例KOA患者随机分为针刺组（21例，脱落1例）和假针刺组（21例，脱落1例）。针刺组从本课题组制定的半标准化针刺方案穴位库中选取5~6个局部穴位（犊鼻、内膝眼、鹤顶、阴陵泉、血海、足三里等）、3~4个远端穴位（风市、外丘、悬钟、足临泣等）进行常规针刺；假针刺组选取非经非穴浅刺，两组均留针30 min，每周治疗3次，共8周。分别于治疗前后及治疗后18周随访时记录两组患者膝关节损伤与骨关节炎评分（KOOS）。结果：与治疗前比较，治疗后及随访时两组患者KOOS 5个维度[疼痛、症状（除疼痛）、日常活动、体育与娱乐功能及生活质量]评分均升高（P<0.05），且针刺组治疗后及随访时疼痛及日常活动评分均高于假针刺组（P<0.05）。结论：针刺可减轻膝骨关节炎患者疼痛症状，提高其日常活动能力。.
