Anteromedial positioning of the femoral tunnel in anterior cruciate ligament reconstruction is the best option to avoid revision: a single surgeon registry.
Article in Journal of experimental orthopaedics, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 5 papers, 1 of them a synthesis that pooled it.
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
purposeThe aim of the study is to compare the risk of revision of single-bundle hamstring anterior cruciate ligament (ACL) reconstruction between the anteromedial, transtibial and outside-in techniques.
methodsThis cohort study was based on data from a single surgeon's registry. Patients who underwent primary single-bundle ACL reconstruction with hamstring tendon using the anteromedial portal, transtibial and outside-in technique, operated between 1 November 2003 to 31 December 2016, were eligible for inclusion. A minimum follow-up of 2 years was used, and the end-point of the study was revision surgery.
resultsThe total number of registered surgeries identified was 665; 109 were excluded, and 556 was the final sample. The overall revision rate was 8.7%. The transtibial technique presented 14/154 [9.9%] of revisions, the transportal 11/96 [11.4%] and the outside-in 22/306 [7.2%]. Separating the outside-in group into central outside-in and anteromedial (AM) outside-in, 18/219 [8.2%] was found for the central outside-in and 4/87 [4.5%] for the AM outside-in technique. Statistical evaluation of the first comparison (transtibial vs. transportal vs. outside-in) obtained p = (n.s.) The second comparison (transtibial vs. central transportal vs. central outside-in vs. AM outside-in, p = (n.s). Placement was also evaluated: high anteromedial placement (transtibial) vs. central (transportal and central outside-in technique) vs. AM placement (AM outside-in). The high AM placement presented 14/154 [9.9%] of revision, the central placement 29/315 [9.2%] and the AM placement 4/87 [4.5%], p = (n.s.) The AM placement was also compared with the other placements (high and central AM), p = (n.s.)
conclusionBased on the registry of a single surgeon during 14 years of ACL reconstruction, the placement of the femoral tunnel in the high anteromedial region was associated with a rupture rate of 9.9%, central placement with 9.2% and anteromedial placement with 4.5%.
