Equal Kinematics Between Central Anatomic Single-Bundle and Double-Bundle Anterior Cruciate Ligament Reconstructions

Can Joint Contact Dynamics Be Restored by Anterior Cruciate Ligament Reconstruction?

“…The ability of DB ACL reconstruction to restore normal rotational kinematics during functional activity remains controversial [18,20,24,26]. We therefore determined whether the in vivo knee kinematics (tibial anterior translation and axial rotation) and joint contact mechanics (tibiofemoral sliding distance) during a high-demand, functional activity (downhill running) would be restored to normal by the DB or SB ACL reconstruction.…”

“…Advocates of DB ACL reconstruction propose DB reconstruction could provide better rotational stability than SB reconstruction based on several in vitro studies [7,31,39,40], although other in vitro studies do not support this [19,20,24]. Several recent in vivo studies using dynamic, functional activities (ie, jumping and cutting) [13,18,26] demonstrated rotational kinematics after DB ACL reconstruction were closer to normal than that after SB ACL reconstruction while other reports of rotational kinematics during walking, descending from a platform, and pivoting [11,34] have found no differences between SB and DB ACL reconstructions.…”

Technique of anatomical single bundle ACL reconstruction with rounded rectangle femoral dilator

“…Therefore, our rationale for developing the rounded rectangle dilators was the ability of the rounded rectangle tunnels to more closely mimic the femoral footprint (compared to the rounded tunnels). In addition, Ho et al [18] and Sastre et al [10] have reported that anatomical single bundle ACL reconstruction and double bundle ACL reconstruction provide very similar stability. Thus, attention has returned to single bundle reconstruction with the graft placed at the center of the anatomical position.…”

Anatomical single bundle anterior cruciate ligament reconstruction

“…They concluded that double bundle reconstruction may not offer a significant advantage over single bundle [38]. Ho et al showed equal kinematics using central anatomic single bundle compared to double bundle reconstruction [39].…”
