计算机辅助手术系统与关节镜下前交叉韧带重建

COMPUTER ASSISTED SYSTEMS FOR ARTHROSCOPIC RECONSTRUCTION OF ANTERIOR CRUCIATE LIGAMENT

目的针对近年多种导航系统用于前交叉韧带的重建手术,探讨计算机辅助手术系统如何改善前交叉韧带重建。方法广泛查阅近年国内外相关文献,分析目前较常用的计算机辅助系统(OthoPilot系统、Bone Morphing系统及透视导航系统)在术中的应用。结果计算机辅助系统通过三维的可视化定位装置,提高了隧道定位的精确度,按照解剖和等距参数,避免移植腱与股骨髁间窝切迹的撞击,实现了患者个体化前交叉韧带的准确定位植入。结论计算机辅助手术系统能更好地评估手术的精确度和可行性,满足了术者手术优化的要求,改善了手术的临床结果。

Objective To introduce several navigation systems in anterior cruciate ligament reconstruction and to investigate the application of navigation systems for the improvement in reconstruction of the anterior cruciate ligament. Methods The related literature was reviewed extensively, and the main current computer assisted surgery systems （OthoPilot system, Bone Morphing system, Fluoroscopic-based system, etc） for utilization in the anterior cruciate ligament reconstruction were analyzed. Results The computer-assisted systems can enhance the accurate placement of tunnels. According to the anatomical and isometric parameters, graft impingement on the intercondylar notch could be avoided, and individual ideal implantation using 3D visualization localisers was achieved. Conclusion It is possible that computer-assisted systems will enable surgeons to better acquire the accuracy and reliability of the various operative techniques, to meet the demand of surgeon＇s surgical optimisation and to improve the clinical results.
