摘要:

背景:目前计算机辅助导航技术已经越来越多地应用于全膝关节置换中。计算机辅助导航全膝关节置换是否比传统全膝关节置换更具优势目前尚无定论。
目的:系统评价计算机辅助导航和传统全膝关节置换后肢体和假体力线的恢复情况。
方法:计算机检索2013年6月前PubMed/Medline、EMBASE、Cochrane CENTRAL、ScienceDirect数据库,纳入计算机辅助导航和传统全膝关节置换的随机对照试验,应用Cochrane协作网提供的RevMan 5.2.5软件进行Meta分析。选取髋-膝-踝机械轴或胫股关节角、股骨假体冠状角、股骨假体矢状角、胫骨假体冠状角、股骨假体矢状角5个指标进行比较,以偏离中线2°或3°确定为力线不良。
结果与结论:共纳入19篇随机对照试验文献,共2 654例(3 392膝)。Meta分析结果显示,计算机辅助导航全膝关节置换后机械轴恢复精确率明显优于传统全膝关节置换,其中偏倚3°时,P < 0.000 01;偏倚2°时,P=0.000 8。计算机辅助导航全膝关节置换后股骨假体冠状角恢复精确率(3°)明显优于传统全膝关节置换(P=0.002);偏倚2°时两种方案差异无显著性意义(P=0.290)。计算机辅助导航全膝关节置换后股骨假体矢状角恢复精确率(3°)明显优于传统全膝关节置换(P=0.040);偏倚2°时两种方案差异无显著性意义(P=0.950)。计算机辅助导航全膝关节置换后胫骨假体冠状角恢复精确率明显优于传统全膝关节置换,偏倚3°时,P=0.000 7;偏倚2°时,P=0.002。计算机辅助导航全膝关节置换后股骨假体矢状角恢复精确率(3°)明显优于传统全膝关节置换(P=0.030);偏倚2°时两种方案差异无显著性意义(P=0.260)。提示计算机辅助导航全膝关节置换后肢体力线、股骨/胫骨假体力线偏倚3°以内的精确率均优于传统全膝关节置换,但股骨假体冠状角、股骨假体矢状角、股骨假体矢状角偏倚2°以内的精确率两种方案无明显差异。

Abstract:

BACKGROUND: Computer-assisted navigation technique has been widely applied in total knee arthroplasty. However, whether computer-assisted navigation total knee arthroplasty is better than traditional total knee arthroplasty remains unclear.
OBJECTIVE: To systemically evaluate and compare the limb and prosthesis alignment restoration post computer-assisted navigation and traditional total knee arthroplasty.
METHODS: The PubMed/Medline, EMBASE, Cochrane CENTRAL, ScienceDirect database were searched from established to June 2013 and the randomized controlled trials about computer-assisted navigation and traditional total knee arthroplasty were selected. Meta analysis was performed with Rev Man 5.2 software. The evaluating data included the hip-knee-ankle mechanical axis or tibiofemoral angle, femoral prosthesis coronal angle, femoral prosthesis sagittal angle, tibial prosthesis coronal angle, and tibial prosthesis sagittal angle. The malalignment was defined as a deviation 2° or 3° from the natural line.
RESULTS AND CONCLUSION: 19 randomized controlled trials involving 2 654 cases (3 392 knees) were included in this study. Meta-analysis showed that, the limb alignment restoration post computer-assisted navigation was significantly better than traditional total knee arthroplasty (3°, P < 0.000 01 and 2°, P=0.000 8). The 3° of femoral prosthesis coronal angle deviation post computer-assisted navigation was significantly superior to traditional total knee arthroplasty (P=0.002), while the 2° deviation had no significant difference between the two surgeries (P=0.290). The 3° deviation of femoral prosthesis sagittal angle post computer-assisted navigation was significantly better than traditional total knee arthroplasty (P=0.040); however, the 2° deviation had no significant difference between the two surgeries (P=0.950). 3° and 2°tibial prosthesis coronal angle deviation post computer-assisted navigation was significantly superior to traditional total knee arthroplasty (3°, P=0.030); the 2° deviation had no significant difference between the two surgeries (P=0.260). Computer-assisted navigation has better limb alignment, femoral and tibial prosthesis alignment 3° deviation than the traditional total knee arthroplasty, but the 2° deviation of femoral prosthesis coronal angle, femoral prosthesis sagittal angle, and tibial prosthesis sagittal angle had no significant difference between the two surgeries.
