Femoral tunnel placement has a great influence on the clinical outcome after PCL reconstruction.
Using a robotic/universal force moment sensor (UFS) testing system, we examined joint kinematics and in situ forces of human knees following soft-tissue single bundle PCL reconstruction fixed at the center of the femoral attachment.
Posterior tibial translation significantly increased at all flexion angles after transsection of the posterior cruciate ligament (p<0.05). PCL reconstruction resulted in significantly less posterior tibial translation at all flexion angles when compared to the PCL deficient knee (p<0.05). The differences in the in situ force between the intact ligament and the reconstructed graft were statistical significant (p<0.05).
Single bundle PCL reconstruction with a soft-tissue graft fixed at the center of the femoral attachment is able to reduce the posterior tibial translation significantly. However, it cannot restore kinematics of the intact knee and in situ forces of the intact PCL.
在PCL重建术后,股骨隧道的位置对临床结果有很大影响。
使用机器人/通用力传感器(UFS)测试系统,我们检查了在股骨附着点中心固定的软组织单束PCL重建术后人体膝关节的关节运动学和原位力。
在切断后交叉韧带后,所有屈曲角度下胫骨后移均显著增加(p<0.05)。与PCL缺损膝关节相比,PCL重建在所有屈曲角度下均导致胫骨后移显著减少(p<0.05)。完整韧带与重建移植物之间的原位力差异具有统计学意义(p<0.05)。
采用固定于股骨附着点中心的软组织移植物进行单束PCL重建能够显著减少胫骨后移。然而,它无法恢复完整膝关节的运动学和完整PCL的原位力。
