Quantitative Evaluation of Transtibial Aiming Accuracy in Anterior Cruciate Ligament 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
Background Precise femoral tunnel placement is a critical determinant of anterior cruciate ligament (ACL) reconstruction success. This study aimed to evaluate the accuracy of transtibial aiming in relation to a predrilled anatomic femoral tunnel using radiographic and intraoperative photographic measurements. Methodology In total, 43 single-bundle ACL reconstructions with hamstring autografts were analyzed. After drilling the femoral tunnel through the anteromedial portal, a 4-mm offset guide was inserted transtibially toward its center. Tibial tunnel angles were measured in coronal and sagittal planes, and the absolute distance (D) between the centers of the femoral tunnel and the transtibial K-wire was recorded. A normalized index (I = D/radius, R) was calculated, with I <1 indicating that the transtibial wire remained within the tunnel perimeter. Results The mean femoral tunnel diameter was 7.44 mm (R = 3.72 mm), mean D was 4.50 mm (1.75-6.85 mm), and the overall mean index was 1.2. For tunnels of 7.0 and 7.5 mm, the mean index exceeded 1, while for tunnels of 8.0-9.0 mm, it was less than 1. Deviation showed no correlation with tibial tunnel angulation. In no case did the transtibial K-wire reach the exact femoral center. Conclusions The findings of this study demonstrated that transtibial aiming lacks sufficient precision for anatomic femoral tunnel placement, supporting the anteromedial portal approach as the more accurate technique.
