A Comparison of Results in Early and Late Arthroscopic ACL Reconstruction Using Autogenous Hamstring Tendon

並列摘要


ACL reconstruction, which has had highly satisfactory results, is the treatment of choice. Controversies exist over whether the most suitable period for reconstructing the ACL is at the early stage or after the joint inflammation has disappeared. The purpose of this study was to evaluate the results of patients with early and late ACL reconstructions. We evaluated the differences in the clinical functional results, as well as any complications that appeared in the two groups, to determine the possible indications and benefits of early and late treatment. Since 1996, 53 patients with primary diagnosis of ACL rupture were selected in our study and underwent arthroscopically assisted ACL reconstruction using autogenous quadrupled semitendinosus tendon. All early and late reconstructions were performed by one surgeon surgeon who used the same technique. In group A (total 24; M=17, F=7; mean age 20.7 yrs.) the ACL reconstruction was done within 3 weeks. In group B (total 29; M=20, F=9; mean age 22.3 yrs.), the ACL reconstruction was done between 3 and 27 months after injury. Clinical evaluation and instability, we used the Lysholm scale, IKDC and KT-1000. In Lysholm’s scale, there were no significant difference between group A and B (good to excellent : 91.7% Vs 92.6% ; P>0.05). In IKDC rating system, there were also no significant difference in both groups (normal to near normal : A Vs B=83.4% Vs 79.5% ; P>0.05). In results of KT-1000, the group B seemed more laxity. The incidence of arthrofibrosis was only 8.3% in the group A. Early reconstruction of the ACL could be advocated in young patients with high professional motivations to prevent the onset of greater instability or secondary degenerative lesions.
