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

objectiveTo propose and verify the biomechanical properties of a new double-row suture anchor combined with figure-of-eight cross tension band technology for the treatment of inferior pole fractures of the patella, in order to overcome the shortcomings of traditional fixation methods in achieving stable fixation and reducing implant-related complications.

methods(1) Based on clinical CT data, a three-dimensional finite element model of patellar inferior pole fracture was reconstructed, and the new fixation technology (deep double-row anchors in the proximal bone fragment combined with figure-of-8 sutures) and Kirschner wire tension band wire fixation (TBW) were simulated and analyzed. Mechanical performance in the treatment of inferior pole fracture of the patella; (2) Divide the model into two groups according to surgical methods: suture anchor (SA) fixation group and TBW fixation group; (3) Carry out finite element analysis to compare the two groups at 500 Displacement and stress distribution of the knee joint at 45°and 135°of flexion under N load.

resultsFinite element analysis and biomechanical test results showed that there was no significant difference in displacement and stress between the two groups at different flexion angles.

conclusionDouble-row anchors combined with figure-of-eight suture technology exhibited excellent biomechanical properties, and is a feasible fixation solution for the treatment of inferior pole fractures of the patella.This technology can significantly reduce stress concentration and the risk of implant complications, providing a minimally invasive solution to replace traditional metal implants and helping patients recover early, but its long-term efficacy still requires further clinical verification.
