Adolescence risk factors for meniscus and ligamentous knee injuries in adulthood: A longitudinal study.
Article in Knee surgery, sports traumatology, arthroscopy : official journal of the ESSKA, 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
purposeOur aim is to investigate the influence of adolescent health-related behaviours on the occurrence of meniscus and ligament injuries in a large cohort of Finnish adolescents with an average 27-year follow-up.
methodsThe baseline data were surveys conducted biannually from 1981 to 1997, and these were individually linked to outcomes, as well as meniscus and ligamentous knee injuries obtained from the Care Register for Health Care. A total of 47,747 participants were included. Of these, 22,020 were male and 25,727 were female. A Cox regression model was used to analyze the associations between exposure variables in adolescence (physical activity in sports clubs, other physical activity, overweight, smoking, monthly drunkenness, presence of chronic disease, family socioeconomic status) and the risk for knee injuries. Adjusted hazard ratios (aHR) with 95% confidence intervals (CIs) were computed.
resultsThe mean follow-up time among the participants was 26.8 years (standard deviation [SD]: 4.1 years). A total of 1163 (2.4%) persons suffered a meniscus injury, and 1831 (3.8%) suffered a ligament injury. High physical activity in sports clubs (aHR: 2.02, CI: 1.85-2.21), overweight (aHR: 1.37, CI: 1.12-1.68), monthly drunkenness (aHR: 1.37, CI: 1.19-1.57) and presence of chronic disease (aHR 1.30, CI 1.08-1.56) increased the risk for meniscus injuries. Similarly, high (aHR: 1.72, CI: 1.60-1.84) physical activity in sports clubs, overweight (aHR: 1.26, CI 1.07-1.47), monthly drunkenness (aHR: 1.26, CI 1.13-1.41) and presence of chronic disease (aHR: 1.36, CI: 1.17-1.57) increased the risk for ligament injuries.
conclusionsFrequent physical activity in sports clubs presented a higher risk for meniscus and knee ligament injuries in individuals under 40, compared to degenerative factors such as being overweight or smoking. Interventions focusing on the suitable load level among adolescents with frequent and high-intensity physical activity, in addition to efforts to reduce negative habits should be prioritized to lower the knee injury risk. LEVEL OF EVIDENCE: Level II.
