全膝关节置换后服用健脾益气活血方患者肌力及疼痛的变化

Changes in muscle strength and pain in patients receiving Jianpi Yiqi Huoxue Formula after total knee arthroplasty

背景:全膝关节置换后仍有部分患者存在术肢乏力、疼痛改善不理想的情况,临床发现健脾益气活血方可促进全膝关节置换后康复,但具体疗效仍然有待研究。目的:观察健脾益气活血方对初次单侧全膝关节置换后术肢肌力及疼痛的影响。方法:选择74例行初次单侧全膝关节置换的患者,随机分为试验组及对照组,每组37例。两组患者均采用相同手术方式及假体,对照组术后予常规止痛、抗凝、功能锻炼等治疗;试验组术后在对照组治疗基础上服用健脾益气活血方,持续治疗并随访1个月,统计两组术前、术后肌力(屈伸肌群峰力矩、总功量)、目测类比评分、美国特种外科医院评分的变化。结果与结论:①术后14 d及1个月,试验组的伸肌峰力矩、屈肌峰力距、伸膝总功量、屈膝总功量及美国特种外科医院评分相较于对照组改善更佳(P<0.05);②术后7,14 d及术后1个月试验组的目测类比评分相较于对照组改善更佳(P<0.05);③提示健脾益气活血方可有效提高术肢肌力情况,改善患者术后肢体疼痛,加快患者全膝关节置换后的康复。

BACKGROUND:Some patients still have unsatisfactory improvement of operative limb fatigue and pain after total knee arthroplasty.Clinical findings show that Jianpi Yiqi Huoxue Formula can promote recovery after total knee arthroplasty,but the specific efficacy remains to be studied.OBJECTIVE:To observe the effect of Jianpi Yiqi Huoxue Formula on the muscle strength and pain of the operated limb after the primary unilateral total knee arthroplasty.METHODS:A total of 74 patients undergoing primary unilateral total knee arthroplasty were randomly divided into a trial group and a control group with 37 patients in each group.All patients received the same prostheses and surgical methods during the operation.Patients in the control group were treated with routine analgesics,anticoagulant drugs and functional exercise after the operation.The trial group received Jianpi Yiqi Huoxue Formula after the treatment in the control group.Both groups were treated continuously and followed up for 1 month.The changes in isokinetic muscle strength(peak torque and total work amount of extensor and flexor),visual analog scale score and the hospital for special surgery score of the two groups were analyzed.RESULTS AND CONCLUSION:(1)The trial group had better improvement in peak torque and total work amount of extensor and flexor and the hospital for special surgery score than the control group 14 days and 1 month after surgery(P<0.05).(2)In contrast to the control group,the visual analog scale score of the trial group improved better at 7 and 14 days and 1 month after surgery(P<0.05).(3)It is indicated that Jianpi Yiqi Huoxue Formula can effectively improve the muscle strength of the operated limb,enhance the degree of postoperative joint pain,and promote functional rehabilitation after total knee arthroplasty.
