Limited accuracy of transtibial aiming for anatomical femoral tunnel positioning in ACL reconstruction.

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
backgroundAnterior cruciate ligament (ACL) rupture is a common knee injury, and with advancements in knee arthroscopy, ACL reconstruction has become common. Techniques like single-double bundle and femoral tunnel drilling via transtibial or anteromedial portal approaches are available. This study evaluates the accuracy of femoral tunnel placement via these approaches in single-bundle ACL reconstruction. MATERIALS AND
methodsForty-three ACL reconstructions using hamstring grafts were analyzed. Initially, femoral tunnels were drilled via the anteromedial portal from 09:30 to 10:00 (14:00 to 14:30 for left knees). Tibial tunnels (mean anteroposterior angle: 63.5°, sagittal: 64.2°) were then created with the same diameter, accompanied by radiological documentation. A femoral aiming device was used to place a K-wire at the center of the femoral tunnel, recorded photographically. Tunnel diameters included 7 mm (20 cases), 7.5 mm (11 cases), 8 mm (7 cases), 8.5 mm (3 cases), and 9 mm (1 case). Two observers evaluated all radiological and photographic data, focusing on the deviation of the transtibial K-wire from the femoral tunnel center.
resultsOf 38 evaluated cases, the transtibial K-wire was within the femoral tunnel in 11 cases (28.9%) - 7 cases with 7 mm, 2 cases each with 7.5 mm and 8 mm diameters. In 23 cases (60.5%), the K-wire was at the perimeter or outside the femoral tunnel - 11 cases with 7 mm, 8 with 7.5 mm, 4 with 8 mm, 3 with 8.5 mm, and 1 with 9 mm diameters.
conclusionTranstibial aiming for anatomical femoral tunnel positioning is challenging. No significant correlation was found between the transtibial deviation and the tibial tunnel diameter.
