Impact of BMI on Two-year Outcomes Following Meniscal Repairs and Meniscectomies in Pediatric and Adolescent Patients: A Nationwide Cohort Analysis.
Article in Journal of the Pediatric Orthopaedic Society of North America, 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
Background: The prevalence of meniscus injuries and subsequent reconstructions is increasing. Youth obesity has also increased and may put patients at a higher risk of post-operative complications. Hypothesis/purpose: Our aim was to assess post-operative medical and orthopaedic outcomes as well as healthcare utilization following meniscus repairs and meniscectomies in pediatric and adolescent patients. We hypothesized that patients with a higher BMI would exhibit higher rates of post-operative complications. Methods: The TriNetX database was queried for patients 21 years of age or younger with a history of meniscus repairs or meniscectomies, yielding 8,355 patients. Three analyses were performed comparing patients with a BMI = 18.5-24.9 (healthy weight) to BMI ≤ 18.5 (underweight), BMI = 25-30 (overweight), and BMI = 30-35 (obese). Frequency of medical and orthopaedic complications as well as healthcare utilization was analyzed at 30, 90, and 180 days. Orthopaedic complications were also assessed at 2 years post-operatively. After Bonferroni correction, Results: Rates of most medical and orthopaedic complications were low in the overall cohort, never exceeding 0.43% and 1.22%, respectively. Prevalence of ED visits peaked at 4.21% at 180-day follow-up. The overall rate of revision meniscal surgery within 2-years was 9.08%. All medical outcomes and healthcare utilization rates were comparable between BMI cohorts. Conclusions: Regardless of a patient's BMI, meniscus repairs and meniscectomies are generally safe in young patients. Key Concepts: (1)Meniscus repairs and meniscectomies are safe procedures for children.(2)Body mass index does not impact post-operative medical outcomes.(3)Unlike adults, obesity does not impact post-operative orthopaedic outcomes and rates of revision surgery. Level of Evidence: III.
