Bilateral Simultaneous Patellar Tendon Rupture in an Adolescent Athlete: A Case Report and Literature Review Highlighting the Role of Vitamin D Deficiency.
Article in Cureus, 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
Simultaneous bilateral patellar tendon rupture is an exceptionally rare injury in the paediatric population. While bilateral patellar tendon rupture in adults is frequently associated with systemic disease or corticosteroid exposure, the few reported paediatric cases have been linked to localised tendinopathy, connective tissue disorders, or repetitive mechanical stress. This report presents a case of simultaneous bilateral patellar tendon rupture in a 15-year-old male following a rugby-related injury. Biochemical investigation revealed severe vitamin D deficiency with secondary hyperparathyroidism in the absence of systemic illness, corticosteroid use, or renal dysfunction. The patient underwent prompt bilateral surgical repair followed by structured rehabilitation and vitamin D supplementation without complications. This case represents an unusual presentation of bilateral patellar tendon rupture in an otherwise healthy adolescent and highlights the coexistence of severe vitamin D deficiency as a potentially relevant metabolic finding. Although causality cannot be inferred from a single case, recognition of potential underlying metabolic abnormalities may aid diagnostic evaluation and inform management in similar rare presentations.
