Double-Bundle ACL Reconstruction

Abstract

Although the outcomes of single-bundle anterior cruciate ligament (ACL) reconstruction have been favorable, multiple authors have noted persistent instability and residual pain in a subset of patients following this surgery. Consequently, interest has increased in the use of double-bundle ACL reconstruction to provide a better restoration of knee anatomy, kinematics, and biomechanics. Recent biomechanical studies have suggested that double-bundle ACL reconstruction may provide better anteroposterior and rotational stability than single-bundle reconstruction. Short-term results have been favorable; however, long-term clinical studies are needed to determine whether double-bundle ACL reconstruction results in improved patient outcomes compared with single-bundle techniques.
