Anterior cruciate ligament (ACL) tears are rarely found without remnant tissue. Remnant tissue is usually found either attached to the posterior cruciate ligament (PCL) or bridging the femoral and tibial footprints. Keeping the remnant tissue intact during ACL reconstruction has been favored because it has been thought to promote revascularization of the graft and recovery of joint position sense. However, in our experience, we found that using the remnant preserving technique for ACL reconstruction led to unexpected complications such as blockage of the arthroscopic view by the remnant tissue itself and separation of the remnant tissue during tunnel formation. To overcome these complications associated with the remnant-preserving technique, we developed a novel technique using an adjunct anterolateral portal and a polydioxanone suture to stabilize remnant ACL tissue in place.
