Abnormal patellar sagittal spatial kinematics in patients with patellofemoral pain: an in vivo dynamic CT study.

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
backgroundPatellofemoral joint kinematics is a complex three-dimensional(3D) motion, involving shift and rotation in the coronal, sagittal, and axial directions. Quantifying patellar tracking only at the axial level of the patella or with two-dimensional(2D) parameters may not be comprehensive. The current study sought to explore the spatial kinematics characteristics of the patella in three directions, especially the sagittal plane in patients with patellofemoral pain (PFP) based on Four-dimensional computed tomography (4D-CT).
methodsA total of 35 knees with PFP and 35 controls from March 2023 to May 2024 were evaluated. 3D shift and tilt of the patella were measured in the patellofemoral joint coordinate system established by MIMICS. The 3D shift and tilt of the patella in three directions (coronal, sagittal, and axial) were evaluated. Differences between groups were analyzed using two-way repeated measures ANOVA.
resultsThe 3D tilt
conclusionIt is necessary to evaluate the spatial position characteristics of the patellofemoral joint and the stability of the patella from multiple planes and angles at the dynamic level. Analyzing the spatial multi-plane kinematic characteristics of the patellofemoral joint may help in determining the etiology of PFP.
