Stability of the Knee Joint After Single and Double Bundle Anterior Cruciate Ligament Reconstruction

The purpose of this prospective study is to evaluate the influence of both bundles on the knee stability - anterior-posterior translation, internal and external rotations after the double-bundle reconstruction of Anterior Cruciate Ligament (ACL) and to compare the stability after single-bundle and double-bundle reconstruction using a computer navigation system. Methods Anterior-posterior translation, internal rotation, and external rotation were recorded in the deficient condition (without ACL), in the anteromedial-reconstructed, posterolateral-reconstructed, and in the whole ACL-reconstructed condition for double-bundle reconstructions and before and after the ACL reconstruction in single-bundle group. KT-1000 was used to evaluate anterior-posterior translation.
