Several techniques of anterior cruciate ligament (ACL) double-bundle reconstruction have been introduced to improve the functional
outcome and restore normal kinematics of the knee. Meanwhile, a remnant-preserving technique was developed to preserve the
proprioception and to enhance the revascularization of the reconstructed ACL. We developed double-bundle ACL reconstruction
technique using autogenous quadriceps tendon graft while preserving the remnant. With this technique, two femoral sockets
and one tibial tunnel are made. To preserve the remnant of the ACL, the rotational direction of the reamer was set to counterclockwise
just before perforation of the tibial tunnel. To pass the graft more easily without disturbance of the remnant, the graft
passage was achieved through the tibial tunnel. We suggest that the remnant-preserving technique could be an effective alternative
considering its mechanical stability as well as the proprioception and vascularization recovery in arthroscopic double-bundle
ACL reconstruction.
