摘要:
目的:观察关节腔内注射倍他米松和玻璃酸治疗老年膝骨关节炎的临床疗效及安全性.方法:选取我院2012年7月-2015年7月收治的老年膝骨关节炎患者76例,以随机数字表法分为对照组和观察组,各38例.对照组患者给予关节腔内注射玻璃酸钠注射液2 mL,每周1次,连用3周;观察组患者第1周给予复方倍他米松注射液1 mL,后两周给予玻璃酸钠注射液,每次2 mL,每周1次.比较两组患者的临床疗效和不良反应发生情况,以及治疗前后的视觉模拟评分法(VAS)评分、西安大略和麦克马斯特大学骨关节炎量表(WOMAC)评分、生活质量综合评定问卷(GQOLI-74)评分和基质金属蛋白酶(MMP)水平.结果:观察组患者的总有效率为92.11%,显著高于对照组的73.68%,差异有统计学意义(P0.05);治疗后,两组患者的VAS、关节僵硬、关节疼痛和日常活动受限评分,以及MMP-1、MMP-3水平均较治疗前显著下降,躯体疼痛、生理功能、生理职能、活力、社会功能、情感职能、精神健康及GQOLI-74总评分均较治疗前显著升高,且观察组各指标显著优于对照组,差异均有统计学意义(P0.05). After treatment,VAS,joint stiffness,joint pain and daily activity re-striction score as well as MMP-1,MMP-3 were decreased significantly in 2 groups,compared to before treatment;physical pain, physiological function,physiological limitations,vitality,social function,emotional function,mental health and GQOLI-74 total score were increased significantly,and the each index of observation group was significantly better than that of control group,with statistical significance(P<0.05). No obvious ADR was found in 2 groups during treatment. CONCLUSIONS:The intraarticular in-jection of betamethasone and sodium hyaluronate in the treatment of elderly knee osteoarthritis can effectively reduce pain degree, improve knee function and quality of life,have good therapeutic efficacy and safety,the mechanism of which may be associated with the reduction of MMP level.
