Rotation matters: CT and MRI yield different tibiofemoral rotation angles in patellofemoral patients. An investigational plateau-anchored MRI method is descriptively associated with a smaller mean CT-MRI difference.

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
Purpose: To compare tibiofemoral rotation (TFR) measured on magnetic resonance imaging (MRI) and computed tomography (CT) in patellofemoral (PF) patients and descriptively report mean differences using an alternative plateau-anchored MRI measurement method. Methods: Surgical candidates for tibial derotational osteotomy with both CT and MRI were retrospectively reviewed. Demographics/surgical indication/tibial torsion were recorded. TFR was measured on CT/MRI using standard posterior condylar-posterior tibial axis technique. A plateau-anchored MRI method utilizes the angle between the distal femoral posterior condylar axis and the axis connecting the proximal tibial plateau's most medial and lateral aspects. Paired Results: Fifty-eight knees/46 patients (50 female; mean age 21 ± 7 years; body mass index [BMI] 25 ± 6 kg/m Conclusion: CT and MRI yield systematically different TFR values in the same PF patients; standard MRI yielding lower values than CT. A plateau-anchored MRI method yielded a smaller mean difference relative to CT than the standard MRI method in this cohort. These results should not be interpreted as demonstrating interchangeability, accuracy, or clinical readiness of the plateau-anchored method. Level of Evidence: Level II.
