The relevance of proprioception function and the reservation of residual fiber in the anterior cruciate ligament reconstruction / 中华骨科杂志

ABSTRACT

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(P＜0.05),and Group C showed a significant difference between the test side and control side at the flexion of 30°-0°(P＜0.05),but Group D showed no significant difference at the 3 flexion ranges(P＞0.05).Conclusion During double-bundle ACL reconstruction,with the reservation of tibial residual tom 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.
