Artificial intelligence in ACL injury prediction and prevention: a systematic review.
Synthesis in Journal of orthopaedic surgery and research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundAnterior cruciate ligament (ACL) injuries are prevalent in sports, with significant physical, economic, and long-term health impacts. Artificial intelligence (AI) offers promising solutions for predicting and preventing ACL injuries through advanced data analysis. This systematic review evaluates AI applications in ACL injury prediction and prevention, focusing on techniques, performance metrics, sports contexts, and intervention effectiveness.
methodsFollowing PRISMA 2020 guidelines, we searched PubMed, Scopus, Google Scholar, and Web of Science from inception to November 1, 2025 for peer-reviewed studies in English using AI for ACL injury prediction or prevention. Studies were excluded if they focused on other injuries or were non-original research. Two reviewers independently screened articles, extracted data (e.g., AI techniques, sample size, outcomes), and assessed methodological quality using the PROBAST + AI. Narrative synthesis was conducted due to methodological heterogeneity.
resultsSeven studies, published between 2019 and 2024, were included, involving 5-880 participants (age range 13-22.8 years) across sports like basketball, handball, and soccer. AI techniques included machine learning (e.g., support vector machines, random forest) and deep learning (e.g., convolutional neural networks), with applications in risk prediction and biomechanical assessment. Predictive models achieved accuracies of 79.5-96% and AUCs of 0.63-0.85, while prevention-focused studies reported high validity (e.g., R
conclusionAI demonstrates significant potential in predicting ACL injury risk and informing prevention strategies through biomechanical and kinematic analyses. However, small sample sizes, heterogeneous methodologies, and practical barriers (e.g., equipment costs) limit clinical adoption. Future research should focus on larger, diverse cohorts and standardized protocols to enhance generalizability and implementation. REGISTRY NUMBER: CRD420251230914.
