Aberrant anterior tibial artery on knee MRI: A case report advocating for routine search of this anatomical variant.
Article in Radiology case reports, 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
An aberrant anterior tibial artery is an anatomical variant in which the anterior tibial artery arises anomalously from the popliteal artery and takes an atypical anterior course relative to the popliteus muscle. We report a case of a 56-year-old male who underwent a routine knee MRI following trauma to evaluate for a suspected meniscal tear. MRI revealed an incidental finding of an aberrant anterior tibial artery coursing anterior to the popliteus muscle and near the posterior tibial cortex. Knowledge of this variant is crucial to avoid potential iatrogenic vascular injury during orthopedic surgery, especially in procedures involving the proximal posterior tibia, such as high tibial osteotomy, total knee arthroplasty, fracture surgery, lateral meniscal repair, or posterior cruciate ligament reconstruction.
