Single Bundle Anterior Cruciate Ligament Reconstruction

ABSTRACT

Anterior cruciate ligament (ACL) reconstruction is generally accepted as the most reliable method of re-establishing knee kinematics so as to prevent various symptoms related to the instability and subsequent injuries to the knee. Double bundle ACL reconstruction has emerged as a potential solution for single bundle reconstruction, as the latter can restore anteroposterior stability, but it had limitations for improving the rotational stability. However, double bundle reconstruction is a more complex surgical procedure and it remain unclear whether double bundle reconstruction has better results than single bundle reconstruction on long term follow-up. Recent studies have demonstrated that a femoral tunnel could be created independently of the tibial tunnel and in a more anatomic position by using the anteromedial portal technique, so that that there is better restoration of the rotational stability as well as anterior stability than that with performing the transtibial technique.
