Ultrasound quantification of knee meniscal extrusion: the potential of weight-bearing and dynamic evaluations. A systematic review.
Article in EFORT open reviews, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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: Meniscal extrusion (ME) can have detrimental effects. The aim of this study was to analyze the evidence about the reliability, potential of standing and dynamic evaluations, and influencing factors identified by using ultrasound (US) to evaluate knee ME. Methods: A systematic review of the literature was performed in February 2024 on PubMed, Scopus, and the Cochrane Library databases to select all articles, dealing with the US evaluation of ME. Relevant data of the involved articles, including study type, number of patients, age, sex, US technique, and data comparison with other radiological examinations, were extracted and collected for the study analysis. Results: Sixty studies on 4,742 patients were included: 38 cross-sectional, ten longitudinal, two case-control, and ten biomechanical studies. A strong correlation was found between MRI and US, with good US sensitivity (96%) and specificity (82%), and moderate to excellent interrater and intrarater reliability. US examinations in the standing position with weight-bearing or more complex dynamic conditions reported a significant influence of weight-bearing on MME. US was able to identify a relationship between meniscus posterior root tear and MME, as well as between ME and both pain and early osteoarthritis. Conclusions: US is a valuable tool for the study of ME and the identification of the association between ME and various conditions. US in dynamic and weight-bearing evaluations is useful to characterize this anatomical abnormality in different pathologies, including OA, meniscal lesions, and in the follow-up of surgical procedures, providing important data to choose the best treatment to address patients affected by ME.
