Higher revision and secondary surgery rates after ACL reconstruction in athletes under 16 compared to those over 16: a case-control study.
Article in Journal of orthopaedic surgery and research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundThe incidence of anterior cruciate ligament (ACL) reconstructions among adolescents, particularly those involved in high-risk sports, has increased. Despite surgical advancements, outcomes remain worse than in adults. This study aimed to assess ACL reconstruction outcomes in patients under 16 years and compared to older patients. The prevalence of high pivoting sports in those undergoing revision or contralateral ACL reconstruction was also analyzed. We hypothesized that younger athletes experience poorer outcomes and higher rates of secondary surgeries.
methodsThis study evaluated ACL reconstruction outcomes in patients under 16 years (Group 1) and compared them with those over 16 years (Group 2). A retrospective analysis was conducted on patients who underwent primary arthroscopic ACL reconstruction between 2007 and 2022. Ipsilateral and contralateral surgeries were analyzed in both groups. Patient-reported outcomes (Lysholm score, Knee Injury and Osteoarthritis Outcome Score [KOOS], Tegner Activity Scale, and International Knee Documentation Committee [IKDC] scores) were compared between the two groups. The impact of sports activity level and sex on revision rates was examined. Statistical tests, including two-sample Z tests and two-sample t-tests, were used for analysis. Secondary surgeries were defined as additional procedures after ACL reconstruction, microfracture, hardware removal, and arthrolysis.
resultsGroup 1 (average age: 15.2 years) included 70 patients with a follow-up of 6.9 years, and Group 2 (average age: 30.8 years) included 87 patients with a follow-up of 3.66 years. A significant age difference was found (p<0.001). Group 1 had higher rates of contralateral ACL surgeries (18.3% vs. 1.1%, p=0.03), meniscus surgeries (26% vs. 4.6%, p=0.003), and secondary surgeries (44% vs. 21%, p=0.01) compared to Group 2. Female athletes under 16 years had a significantly higher rate of contralateral ACL reconstruction (92% vs. 69%, p=0.020). In Group 1, the KOOS Pain score was significantly higher (95.6 vs. 94.0, p=0.033), but the Symptoms score was significantly lower (75.6 vs. 85.0, p<0.005).
conclusionPatients under 16 years undergoing ACL reconstruction had higher rates of both contralateral and ipsilateral ACL surgeries, as well as secondary surgeries, compared to older patients. Female adolescents had a significantly higher incidence of contralateral ACL reconstruction.
