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

Background: Posterior medial meniscal root (PMMR) tears drastically alter knee biomechanics and reduce degenerative risk from a functional meniscectomy. While transtibial pullout (TTP) is a common repair technique, all-suture anchor (ASA) repair alternatively offers a tunnel-less repair construct. This study aimed to compare the radiologic and clinical outcomes of ASA versus TTP repair techniques in patients with PMMR tears. Hypothesis: The ASA technique would yield superior outcomes compared to the conventional TTP method. Study Design: Cohort study; Level of evidence, 3. Methods: This ambidirectional cohort study analyzed patients who underwent repair for isolated PMMR tears between 2018 and 2024. Participants were divided into the ASA and TTP groups with a 1-year follow-up. Radiologic evaluation included magnetic resonance imaging at 9 months and weightbearing radiographs at 1 year postoperatively to assess medial meniscal extrusion (MME), healing status, and cartilage progression according to the International Cartilage Repair Society grading system. Clinical outcomes were assessed concurrently using the International Knee Documentation Committee (IKDC) scores. Results: The final cohort comprised 36 patients (12 ASAs, 24 TTPs) with comparable baseline characteristics. Radiologically, mean postoperative MME increased in both groups (ASA: 3.63 ± 0.82 mm; TTP: 4.32 ± 1.24 mm), although the difference between groups was not statistically significant ( Conclusion: Both ASA and TTP techniques significantly improve functional outcomes for repairing PMMR tears with comparable clinical efficacy. While both groups experienced postoperative meniscal extrusion, the ASA technique showed a trend toward better extrusion control, without significant differences in healing rates or osteoarthritic progression. These findings suggest that ASA repair is a viable alternative to the transtibial pullout method.
