小针刀联合股四头肌运动训练治疗膝骨关节炎临床观察

目的 观察小针刀联合股四头肌运动训练治疗膝骨关节炎（knee osteoarthritis，KOA）的临床疗效。方法 将60例单侧KOA患者随机分为对照组和观察组，每组30例。对照组行股四头肌运动训练，观察组在对照组的基础上行小针刀治疗，疗程均为3周。治疗前、治疗后、随访6周末，分别采用数字评分量表（numerical rating scale，NRS）评价患者膝关节的疼痛程度，采用西安大略和麦克马斯特大学骨关节炎指数（Western Ontario and McMaster Universities osteoarthritis index，WOMAC）评价膝关节病情严重程度。结果 治疗后和随访6周末，两组患者NRS评分和WOMAC的疼痛、僵硬、功能障碍评分和总分均较治疗前显著降低（P＜0.05），观察组患者NRS评分和WOMAC的疼痛、僵硬、功能障碍评分和总分均显著低于对照组（P＜0.05）。结论 小针刀联合股四头肌运动训练治疗KOA具有协同作用，能够减轻膝关节的疼痛、僵硬和功能障碍。

Clinical Effect of Small Needle Knife Combined with Quadriceps Femoris Exercise Training in Treatment of Knee Osteoarthritis

Objective To investigate the clinical effect of small needle knife combined with quadriceps femoris exercise training in the treatment of knee osteoarthritis (KOA). Methods A total of 60 patients with unilateral KOA were randomly divided into control group and observation group, with 30 patients in each group. The patients in the control group received quadriceps femoris exercise training, and those in the observation group were treated with small needle knife in addition to the treatment in the control group; the course of treatment was 3 weeks for both groups. Before treatment, after treatment, and at the end of week 6 of follow-up, numerical rating scale (NRS) was used to evaluate the degree of pain in knee joint, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) was used to evaluate the disease severity of knee joint. Results After treatment and at the end of week 6 of follow-up, both groups had significant reductions in NRS score and the total score and scores of pain, stiffness, and dysfunction of WOMAC (P<0.05), and the observation group had significantly lower NRS score and total score and scores of pain, stiffness, and dysfunction of WOMAC than the control group (P<0.05). Conclusion Small needle knife and quadriceps femoris exercise training have a synergistic effect in the treatment of KOA and can alleviate the pain, stiffness, and dysfunction of knee joint.
