ABSTRACT
Anterior Cruciate Ligament [ACL] tear is one of the most common sport injuries of the knee and arthroscopic reconstruction by bone drilling and graft placement is the accepted treatment. The aim of this study was to compare the results of two different techniques of ACL reconstruction namely transportal [anatomic] and transtibial [non-anatomic] femoral tunnel drilling. In a comparative clinical study, 60 ACL-deficient patients were operated using transportal ACL reconstruction and compared with another 60 patients treated with transtibial technique. They were compared in terms of performance and ligament stability. Our results showed that comparing the two groups, there were no differences in terms of Lysholm score [transtibial: 96.2 versus transportal: 97.2], post-operative Tegner score [transtibial: 6.3 versus transportal: 6.6] and knee range of motion but IKDC score was significantly better in the transportal group [p<0.001]. Anatomic transportal ACL reconstruction technique yields superior results in terms of knee ligament stability comparing to non-anatomic transtibial femoral tunnel drilling
