The proprioceptive sense of the knee is closely related with the function of the knee. It is an unavoidable problem that the proprioceptive sense of the knee alter after ACL being injuried and reconstructed,which deserve far-reaching studies and might affect the therapeutic concept of the injuried ACL or even the injuried knee.We observed the changes of the proprioceptors in the partly injuried ACL and the xenogeneic graft/artificial graft being used to reconstructing the injuried ACL with gold chlorid staining method and laser copolymerization electron micrography method to observe the morphological changes of the neuromechanism in the ligament tissue,with RT-PCR method to evaluate the proportion and the regeneration of the nerve component and with HRP retrograde tracking technology and electrophysiologic study(including SEPs and EMG) to judge the functional changes of the neuromechanism in the ligament tissue,respectively.This paper included 3 sections:Changes of the proprioceptors in the partly injuried ACL;the neural regeneration study after injuried ACL being reconstructed with xenogeneic graft;the neural regeneration study after injuried ACL being reconstructed with artifical graft. |
