Revision Anterior Cruciate Ligament Reconstruction in an Adult Twin With Meier-Gorlin Syndrome.
Article in Ochsner journal, 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: Meier-Gorlin syndrome is a rare autosomal recessive disorder characterized by the clinical triad of microtia, patellar aplasia or hypoplasia, and proportionate short stature. The absence of the patella poses 2 surgical challenges: lack of a donor site for graft harvest and lack of anterior restraint during anterior cruciate ligament (ACL) reconstruction surgery. Given that individuals with Meier-Gorlin syndrome generally exhibit normal cognitive function and life expectancy, ensuring knee stability is essential to support their ability to participate in sports and engage in daily activities independently. Case Report: We present the case of an adult twin with Meier-Gorlin syndrome who had an absent patella and recurrent knee instability after ACL retear. At 2-year follow-up after revision ACL reconstruction, the patient's Single Assessment Numeric Evaluation score had increased to 100 from a preoperative score of 30. The patient reported excellent pain relief and was able to perform all activities of daily living. Conclusion: Successful revision ACL reconstruction is possible in a patient with Meier-Gorlin syndrome. However, these patients may be at higher risk of revision because of the lack of the anterior constraint provided by a normal extensor mechanism with a present patella.
