摘要:

文题释义:
运动力学对线:是行全膝关节置换时的一种下肢对线方法,尽可能还原膝关节患关节炎前的运动状态。
机械力学对线:该对线方法已指导全膝关节置换手术近30年,机械力学对线技术的目标是恢复髋-膝-踝0°角,从而使整个下肢恢复到中立位,近些年研究发现该方法指导的全膝关节置换术后1/5患者对置换效果不满意。

背景:机械力学对线技术虽然保证了膝关节假体的长期生存率,但是仍有部分全膝关节置换患者对置换效果及术后膝关节功能不满意。

目的:采用Meta分析的方法评价运动学对线技术和机械力学对线技术指导全膝关节置换的效果。

方法:检索运动学对线和机械力学对线指导全膝关节置换的临床对照研究文献,检索范围包括中国生物医学文献数据库、万方数据、中国知网、维普数据、PubMed、Cochrane图书馆及Embase,检索年限为建库日期至2019年7月。对检索到的文献进行筛选、质量评价及数据提取,并采用Review Manager 5.3软件进行统计分析。

结果与结论:①共纳入12篇文献,包括945例患者,其中运动学对线组470例,机械力学对线组475例;②荟萃分析结果显示,手术时间方面运动学对线组比机械力学对线组更短[MD=-15.44,95%CI(-27.16,-3.71)],西安大略和麦克马斯特大学骨关节炎指数运动学对线组优于机械力学对线组[MD=-8.40,95%CI(-15.39,-1.40)],牛津大学膝关节评分运动学对线组优于机械力学对线组[MD=4.72,95%CI(0.24,9.21)],机械力学对线组术后的机械外侧股骨远端角及机械内侧胫骨近端角显著大于运动学对线组,以上研究P均< 0.05;③运动学对线组与机械力学对线组在平均住院日、出院前最远行走距离、膝关节协会评分、膝关节伸直角度、术后并发症方面差异无显著性意义(P均> 0.05);④提示运动学对线指导全膝关节置换后的膝关节功能优于机械力学对线,但影像学和围术期结果类似,且术后未增加并发症发生率。说明运动学对线可作为一种下肢力线对线方法来指导全膝关节置换。

Abstract:

BACKGROUND: Although mechanical alignment technique ensures the long-term survival rate of knee arthrosis, some patients are still not satisfied with the effect of total knee arthroplasty and the function of knee joint after operation.

OBJECTIVE: Meta-analysis was used to evaluate the effect of kinematic alignment technique and mechanical alignment technique in the guidance of total knee arthroplasty.

METHODS: The literature of clinical controlled study of kinematic alignment and mechanical alignment in the guidance of total knee arthroplasty published from the date of establishment to July 2019 was searched in Chinese Biomedical Literature Database, Wanfang data, CNKI, VIP data, PubMed, Cochrane Library, and Embase. The literature was screened, and evaluated; data were extracted. Review Manager 5.3 software was used for statistical analysis.

RESULTS AND CONCLUSION: (1) A total of 945 cases were included in 12 articles, including 470 cases in kinematic alignment group and 475 cases in mechanical alignment group. (2) The results of meta-analysis showed that the operation time was shorter in the kinematic alignment group than in the mechanical alignment group [MD=-15.44, 95%CI(-27.16, -3.71)]. Western Ontario and McMaster University Osteoarthritis Index was better in the kinematic alignment group than in the mechanical alignment group [MD=-8.40, 95%CI(-15.39, -1.40)]. Oxford knee score was better in the kinematic alignment group than in the mechanical alignment group [MD=4.72, 95%CI(0.24, 9.21)]. Distal angle of mechanical lateral femur and proximal angle of mechanical medial tibia were significantly larger in the mechanical alignment group than in the kinematic alignment group (all P < 0.05). (3) There was no difference in average hospitalization day, maximum walking distance before discharge, knee society score, knee joint straightening angle and postoperative complications between kinematic alignment group and mechanical alignment group (all P > 0.05). (4) The function of knee joint after kinematic alignment for guiding total knee arthroplasty was better than that in mechanical alignment group. However, the imaging and perioperative results were similar, and the incidence of complications was not increased after operation. It is suggested that kinematic alignment may be a lower extremity force alignment method to guide total knee arthroplasty.
