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: Meniscal tears are common sports-related injuries, and surgical repairs continue to have undesirable clinical outcomes. Meniscal allograft transplantation is limited by the availability of suitable age-matched and size-matched allografts and poor long-term survival. Segmental meniscal transplantation may improve outcomes by preserving the meniscotibial ligament complex; however, little is known about how surgical techniques influence the biomechanics of such reconstructions. Purpose: To evaluate the biomechanical performance of 2 surgical reconstruction strategies for segmental meniscal transplantation using a cadaveric bovine meniscus model. Study Design: Controlled laboratory study. Methods: A total of 24 bovine meniscus explants (12 medial, 12 lateral) underwent 2 repair techniques (n = 12 per group; 6 medial and 6 lateral per group): (1) Repair 1, using 2 hashtag, 1 vertical rip-stop, and 2 luggage tag sutures; and (2) Repair 2, using 4 luggage, 1 vertical mattress, and 2 horizontal mattress sutures. Half of the specimens (n = 12) underwent quasi-static uniaxial tensile testing to failure; the remaining half underwent 1000 loading cycles before failure. Outcomes included stiffness, maximum force, failure mode, construct deformation, and cyclic survival. Results: Repair 1 demonstrated significantly higher ultimate failure loads in both static (311.9 ± 26.2 N vs. 209.5 ± 82.6 N; Conclusion: A surgical technique combining hashtag sutures with luggage-tag fixation (Repair 1) increased ultimate failure load and reduced the likelihood of cyclic failure, suggesting it may enhance the stability and durability of segmental meniscal repairs. Clinical Relevance: Robust fixation of segmental meniscal repairs may improve surgical outcomes for meniscal deficiency and offer an alternative to full meniscal transplantation.
