Lateral extra-articular procedures in primary anterior cruciate ligament reconstruction reduce graft failure rates in elite and competitive athletes: A systematic review.
Review in Journal of experimental orthopaedics, 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
Purpose: The aim of this systematic review was to evaluate clinical outcomes of combined primary anterior cruciate ligament reconstruction (ACLR) and lateral extra-articular procedures (LEAP) in elite and competitive athletes. Where enough data were available, the review also aimed to differentiate between various LEAP techniques. Methods: A systematic search was conducted following the preferred reporting items for systematic reviews and meta-analyses guidelines using the PubMed, Scopus, Embase and Web of Science databases. Two independent observers screened and assessed the studies; the data were analysed cumulatively where possible and reported narratively. Results: A total of 12 studies met the inclusion criteria, reporting data on 1.719 knees that underwent primary ACLR. An additional LEAP was performed in 783 cases, including anterolateral ligament reconstruction (ALLR), the modified Lemaire and MacIntosh Coker-Arnold techniques. Notably lower graft failure rates were observed, ranging from 0% to 6.5% in the combined ACLR and LEAP groups, compared to 0%-34.0% in the isolated ACLR groups. The cumulative graft failure rate was 3.4% (10/292) for combined ACLR and ALLR, and 2.5% (4/158) for combined ACLR and modified Lemaire, compared to 10.7% (81/758) for isolated ACLR. Return to sport (RTS) rates were similar, ranging from 85.7% to 100% in the combined ACLR and LEAP group, and from 85.6% to 100% in the isolated ACLR group. Conclusion: Based on this study, adding a LEAP to primary ACLR was associated with lower observed graft failure rates and improved knee stability, while return-to-sport rates remained similar in elite and competitive athletes. Level of Evidence: Level IV, systematic review.
