前十字韧带重建术保留残端纤维与本体感觉功能的恢复

 目的 评估前十字韧带重建术中保留残端纤维对本体感觉功能恢复的影响。方法 回顾性分析2009年4至8月接受保留残端纤维的双束前十字韧带 重建术65例患者的病例资料。根据镜下所见断裂前十字韧带胫骨端纤维的残留情况分为四组：无残留组，断裂前十字韧带胫骨端无残余纤维；少量残留组，残余 纤维少于等于全长1/3；中量残留组，残余纤维少于等于全长2/3而多于1/3；多量残留组，残余纤维多于全长2/3。术后1年随访时用磁性角度仪测定三个角度范 围（屈曲90°-60°、屈曲60°-30°、屈曲30°-0°）双下肢被动位置重现误差，对不同组的测量结果进行统计学分析。结果 无残留组和少量残留组在三个测 试角度范围内的手术侧与健侧被动位置重现误差值存在差异（P0.05）。结论 在前十字韧带重建中保留残端纤维对术 后膝关节本体感觉功能的恢复有一定的积极作用。

The relevance of proprioception function and the reservation of residual fiber in the anterior cruciate ligament reconstruction

Objective The purpose of this study is to evaluate the relevance of the recovery of proprioception function and the reservation of residual torn ligamentous fiber in the anterior cruciate ligament (ACL) reconstruction. Methods A retrospective study was carried out in 65 cases of ACL injury, who were treated with double-bundle ACL reconstruction and tibial remnant preservation and tensioning. All the patients were divided into four groups according to the degree of tibial residual fiber observed in the operation, no residual fiber was found(Group A), the length of the residual fiber was less than one third of the normal ACL (Group B), the length of the residual fiber was more than one third less than two thirds of the normal (Group C), the length of the residual fiber was more than two thirds of the normal (Group D). After one year follow-up, the passive angle reproduction test was performed with magnetic angle instrument in 3 flexion ranges (flexion of 90?-60?, 60?-30?, and 30?-0?). All the results were contrasted among the four groups by statistical methods. Results In the passive angle reproduction test of the 3 flexion ranges, Group A and B showed a significant difference between the test side and control side (P0.05). Conclusion During double-bundle ACL reconstruction, with the reservation of tibial residual torn ligamentous and tensioning may have a good effect on the recovery of proprioception function of the knees, which ensure a better functional outcome in the reconstructed knee.
