猪膝关节与人膝关节的对比及其在生物力学测试中的应用

人膝关节结构复杂,韧带较多,其中交叉韧带对维持膝关节的稳定性至为重要.后交叉韧带(posterior cruciate ligament,PCL)对于维持膝关节的后向稳定性和旋转稳定性具有至关重要的作用.PCL损伤后的主观不适症状要明显少于前交叉韧带损伤,所以过去对PCL的关注及研究要少于前交叉韧带.近年来高能量损伤致使PCL的损伤越来越多,学者们对PCL的关注度也在增加,进行了大量与PCL相关的实验,同时我们发现很多学者用动物的膝关节来代替人尸体进行体外生物力学实验,其中猪膝关节应用的最为广泛,基于这种情况,本文就猪膝关节的解剖结构与人的进行了比较,对其在体外生物力学实验中的应用进行了综述.

The Porcine Knee Joint is Compared with the Knee Joint and theBiomechanical Testing of Application

One knee structure is complex,ligament is more,including cruciate ligament in maintaining the stability of the most important.Posterior cruciate ligament to maintain the stability of the knee joint to rotate and after the stability of vital role.PCL after injury subjective symptoms was less than anterior cruciate ligament damage,in the past,PCL attention and research of less than anterior cruciate ligament.In recent years the PCL high-energy injuries of the damage is more and more,to the attention of scholars PCL also increased,with a lot of experiments PCL related,and we find that many scholars made of animal knee to replace human body in biological mechanics experiments,of which the most extensive application porcine knee,based on this kind of situation,this paper the anatomical structure and porcine knee of comparison,the in vitro biological mechanics experiments in this paper reviewed the application.
