Anatomic Double-Bundle Anterior Cruciate Ligament Reconstruction
A review of the literature suggests that a significant number of patients undergoing anterior cruciate ligament (ACL) reconstruction continue to suffer residual pain and instability after surgery. Consequently, there remains considerable room for improvement in surgical ACL reconstruction. Anatomically, the ACL can be divided into 2 major functional bundles, the anteromedial and the posterolate...
متن کاملAnatomic double-bundle anterior cruciate ligament reconstruction: kinematics and knee flexion angle-graft tension relation.
PURPOSE The purpose of this study was to compare the bundle tension curves and resultant knee kinematics between 2 tensioning protocols in anatomic double-bundle anterior cruciate ligament (ACL) reconstruction. METHODS Anatomic double-bundle ACL reconstruction was performed in 7 male cadaveric knees. Each graft was tensioned to 22 N under 2 conditions: (1) both bundles tensioned at 20 degrees...
متن کاملIn vitro and intraoperative laxities after single-bundle and double-bundle anterior cruciate ligament reconstructions.
PURPOSE The purpose of this study was to objectively evaluate whether double-bundle anterior cruciate ligament (ACL) reconstruction can better restore the normal translational and rotational laxities than the conventional single-bundle ACL reconstruction among the reported biomechanical studies. METHODS A systematic literature search was conducted to identify in vitro and in vivo (intraoperat...
متن کاملBiomechanical comparison of anatomic single- and double-bundle anterior cruciate ligament reconstructions: an in vitro study.
BACKGROUND Arthroscopic identification of the anteromedial (AM) and posterolateral (PL) bundle locations of the anterior cruciate ligament (ACL) has facilitated an improved quantitative description of ACL anatomy. Few studies have directly compared the biomechanical laxity of anatomic single-bundle (SB) versus anatomic double-bundle (DB) ACL reconstruction techniques based on precise anatomic d...
