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: There is an opportunity to implement improved techniques for the repair of radial meniscus tears; previous studies have shown a benefit to the addition of rebar or "ripstop" sutures parallel to the tear, forming "hashtag constructs" to strengthen the repair of radial meniscus tears. Studies have not directly compared different types of rebar constructs. Purpose/Hypothesis: The study purpose is to evaluate the biomechanical properties of different suture repair patterns for lateral meniscus tears, including patterns with and without rebar sutures, as well as all-inside and capsule-based constructs. It was hypothesized that the patterns with reinforcing rebar sutures will have a significantly higher load to failure (N). Study Design: Controlled laboratory study. Methods: A total of 68 fresh-frozen lateral human menisci were randomized into 8 groups in 2 rounds of testing. The first round compared rebar and nonrebar suture constructs: 2 simple repairs (double horizontal [DH], cross-stitch [CS]), 1 "hashtag" construct with 2 reinforcing rebar-type sutures parallel to the tear and 2 sutures crossing the tear (all-inside rebar 1 [AIR1]), and an experimental hybrid construct (oblique box [OB]). The second round focused on 4 rebar suture repair constructs that included the box-type "hashtag" suture repair, comparing all-inside and capsule-based repairs: the same all-inside rebar 2 (AIR2) construct as in round 1, 1 all-capsule rebar (ACR) construct with knots tied on the lateral surface, and 2 combined all-inside and capsule-based rebar constructs (combined rebar 1 [CR1] and combined rebar 2 [CR2]). The repaired menisci underwent cyclic loading and load-to-failure testing. Ultimate failure load data were analyzed using analysis of variance testing to compare multiple groups, along with Tukey-adjusted Results: In the first round, the rebar suture construct (AIR1) sustained a higher ultimate load to failure than the other 3 constructs, at 168.6 N, compared with DH (60.3 N), CS (58.2 N), and OB (102.5 N) (analysis of variance Conclusion: Our cadaver study demonstrated that in a model of lateral meniscus radial tear repair, constructs using rebar sutures parallel to the tear provided reinforcement for the sutures spanning the tear and resulted in a higher load to failure when compared with nonrebar suture repair constructs. Clinical Relevance: Surgeons should consider adding parallel rebar sutures to their suture constructs when repairing radial tears arthroscopically to improve the strength of the construct, while maintaining flexibility for various techniques.
