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

Dislocation of the polyethylene insert is a rare complication of total knee arthroplasty (TKA), which has only been described in a handful of case reports. Here, we describe a report of a 55-year-old woman presenting 13 months after the primary TKA with signs of neurovascular compromise. A magnetic resonance image showed posterior extrusion of her polyethylene insert causing a mass effect on the gastrocnemius muscle and the popliteal neurovascular bundle. A multidisciplinary team including a joint reconstruction surgeon, vascular surgeon, and nerve specialist performed a revision TKA with peroneal nerve decompression. The polyethylene insert was noted to be dislocated, rotated 90 degrees, and incarcerated in the posterior knee.
