Evolution of anatomical anterior cruciate ligament reconstruction: a narrative review of double-bundle and rectangular-tunnel techniques.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeAnatomic anterior cruciate ligament (ACL) reconstruction has evolved substantially from procedures aimed primarily at restoring anterior stability toward strategies designed to restore both anterior and rotational stability by reproducing native ACL anatomy, biomechanics, and physiologic knee kinematics. This narrative review summarizes the surgical, biomechanical, and biological concepts underlying this evolution.
methodsA narrative review of the literature on the development of anatomic ACL reconstruction was performed, focusing on tunnel positioning, graft configuration, tensioning, remnant preservation, concomitant meniscal injury, extra-articular augmentation, and posterior tibial slope correction.
resultsThe transition from isometric, transtibial single-bundle reconstruction toward anatomic techniques was driven by recognition of the ACL's dual-bundle structure and broad insertion morphology, leading to double-bundle reconstruction and later morphology-based rectangular tunnel bone-patellar tendon-bone reconstruction. Concurrently, graft tensioning philosophy shifted toward lower, more physiologic tension guided by reciprocal anteromedial-posterolateral bundle behavior, and remnant-preserving techniques emerged to enhance proprioception, vascularity, and graft integration. Concomitant meniscal injury, including ramp lesions and lateral meniscal posterior root tears, is now recognized as an integral determinant of knee kinematics and long-term joint health rather than an incidental finding, reinforcing the concept of ACL injury as a multi-structural pathology. Lateral extra-articular procedures and tibial slope-reducing osteotomy have further addressed graft failure and residual rotational instability in high-risk patients.
conclusionAnatomic ACL reconstruction has progressively shifted from isolated ligament substitution toward individualized, anatomy- and biomechanics-based restoration of comprehensive knee stability, aiming to achieve durable, physiologic knee function through tailored surgical planning.
