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

Hinge constructs can be used in revision total knee arthroplasty in cases of major collateral ligament deficiency, global knee instability, repeated failure of constrained implants, or large bone defects. Although the success of this construct in revision total knee arthroplasty varies depending on the type of surgery and bone quality, hinged implants can solve a wide array of complex problems while preserving stable flexion-extension motion for ambulation. The most common reasons for re-revision include patellofemoral complications, aseptic loosening, and infection. Most cases of mechanical failure for these hinged constructs occur at the hinge component. Here, we report the first instance of catastrophic femoral component failure in a modular rotating hinge via a low-energy mechanism.
