Prediction of patellofemoral instability by quantitative ultrasound elastography device: a feasibility study.
Article in BMC musculoskeletal disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThis study evaluated the reproducibility of shear modulus (SM) measurements of the quadriceps muscle in straight and bent knee positions using a quantitative ultrasound elastography device and explored its potential in predicting patellofemoral instability (PFI).
methodsThe study included 13 healthy subjects and 34 patients with anterior knee pain. Among the 68 legs of 34 patients, 23 had lateral patellar tilt and 9 had patella alta. The SM of the lateral femoral muscle (LFM), medial femoral muscle (MFM), and rectus femoris muscle (RFM) was measured in both knee straight and bent positions using a quantitative ultrasound device. Intra-observer and inter-observer reliability were assessed by intraclass correlation coefficient (ICC), and the performance of SM values in predicting lateral patellar tilt and patella alta was analyzed using receiver operating characteristic (ROC) curves.
resultsSM measurements of the LFM, MFM, and RFM showed good to excellent intra- and inter-observer reliability (ICC = 0.770-0.993, all P < 0.001). The group with lateral patellar tilt showed significantly higher SM(LFM)
conclusionsQuantitative elastography ultrasound for measuring quadriceps muscle SM offers a reliable, noninvasive method for assessing mechanical stress around the knee, providing high predictive accuracy for PFI.
