Abstract

Purpose: The purpose of this study was to compare the clinical outcomes of ACL reconstruction using autogenous hamstring tendon and allo-tibialis tendon. Materials and Methods: Between March 2002 and March 2005, We performed 30 ACL reconstuructions using hamstring autograft and 20 ACL reconstuructions using tibialis tendon allograft. The average follow up period was 22 months in auto-hamstring tendon and 18 months in allo-tibialis tendon. For the clinical evaluation, we measured the Lysholm score, International Knee Documentation Committee(IKDC) score and anterior laxity by KT-2000 arthrometer at final follow up and compare the results between two groups. Results: The Lysholm score improved from 69.5 preoperatively, to 95.3 at final follow-up in the hamstring autograft groups and from 69.0 to 90.4 in the tibialis allograft groups. According to the IKDC evaluation form, 80% of autogenous hamstring tendon group and 73% of allograft group were good results, higher than B(almost normal)(p>0.05). The average KT-2000 arthrometer side-to-side difference, decreased from 7.1mm preoperatively, to 1.8mm at final follow-up in the hamstring autograft groups and from 7.4 mm to 2.4mm in the tibialis allograft groups. Conclusion: The clinical results of ACL reconstruction using auto-hamstring tendon and allo-tibialis tendon showed no significant differences. The allo-tibialis tendon is an acceptable substitute for auto-hamstring tendon in ACL reconstruction.
