摘要(Abstract)：

目的分析等速肌力运动对膝关节骨关节炎(knee osteoarthritis,KOA)患者择期关节置换术后预后的影响。方法选取2017年3月至2020年3月青岛市市立医院收治的100例KOA患者为研究对象,使用随机数字表法将入选患者按1～100编号,将奇数编号者纳入研究组,偶数编号者纳入对照组,每组各50例,所有患者均行择期关节置换术治疗并予常规术后功能锻炼指导。研究组患者在此基础上加用等速肌力运动训练,持续8周。对比两组患者术前、术后8周膝关节功能评分、等速肌力测试结果、膝关节活动度、疼痛评分。结果两组患者手术均顺利完成,随访时间8～17周,中位随访时间10周。术后8周,两组患者患侧膝关节Lysholm评分均显著高于本组术前(均P<0.05),患侧膝关节屈肌、伸肌60°/s、90°/s等速肌力测试峰值力矩(peak torque,PT)、总功量(total work,TW)、平均功率(average power,AP)、单次最大做功量(max rep total work,MRTW)及患侧膝关节屈曲度、屈伸弧度、伸直度均显著大于本组术前(均P<0.05),视觉模拟评分法(visual analogue scale,VAS)评分均显著低于本组术前(均P<0.05)。术后8周,研究组患者患侧膝关节Lysholm评分显著高于对照组(P<0.05),患侧膝关节屈肌、伸肌60°/s、90°/s等速肌力测试PT、TW、AP、MRTW及患侧膝关节屈曲度、屈伸弧度、伸直度均显著大于对照组(均P<0.05),VAS评分显著低于对照组(P<0.05)。结论与常规康复训练相比,接受择期关节置换术的KOA患者术后行等速肌力运动训练能够进一步改善膝关节功能,提高膝关节稳定性和活动度,减轻患者疼痛感。
