1 · What the graph read from 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.

2 · The registry

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

purposeRecent evidence has found the antero-lateral ligament (ALL) may play a role in stabilizing the knee, but its role in anterior cruciate ligament (ACL) reconstruction is controversial. The purpose of the current study is to systematically review and meta-analyze the current evidence in the literature to ascertain whether ACL reconstruction combined with ALL reconstruction affects knee stability, re-rupture rates and patient-reported outcomes compared to ACL reconstructions performed alone.

methodsA literature search was performed based on the PRISMA guidelines. Cohort studies comparing ACL + ALL reconstruction and ACL reconstruction alone were included.

resultsSix clinical trials (LOE I: I, LOE II: 2, LOE III: 3) with 729 patients were included, with a mean follow-up time of 34.2 (24-54.9) months. There was a significant difference in favor of combined ACL + ALL reconstruction for reduced re-rupture rate (2.4% vs 7.3%, p < 0.01), residual positive pivot shift rate (33.3% vs 11.4%, p < 0.01), and reduced KT-arthrometer evaluation (1.6 vs 2.6, p < 0.01). Combined ACL + ALL reconstruction resulted in improved IKDC scores (92.5 vs 87.8, p < 0.01), Lysholm scores (95.7 vs 91.2, p < 0.01) and Tegner scores (6.7 vs 5.7, p < 0.01). There was no significant difference in rate of return to play at the same level (54.3% vs 46.0%, n.s.).

conclusionThe current evidence suggests alongside soft tissue graft ACL reconstruction that concomitant ALL reconstruction improves clinical outcomes, with improved knee stability and lower re-rupture rates. LEVEL OF EVIDENCE: III.
