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

Patellectomy, an uncommon procedure in the current era, poses a challenge in total knee arthroplasty (TKA), creating anteroposterior instability, anterior knee pain, and loss of mechanical advantage. The TKA is even more complicated when the patellectomy is performed secondary to lower limb malalignment with patellofemoral pain and instability. Here, we describe a case of patellectomy and malalignment, and the surgical technique for patellar reconstruction with concomitant TKA to address this complex scenario.
