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

backgroundTo report the long-term results for a single-surgeon consecutive series of Scorpio non-restrictive geometry (NRG) posterior stabilised (PS) total knee replacement (TKR). MATERIALS AND

methodsForty-six consecutive patients who underwent 53 Scorpio NRG PS were identified. Change in range of motion (ROM) and Oxford Knee Score (OKS) over time were recorded. Radiographs were evaluated for alignment and radiolucent lines. Survival analysis for the prosthesis was calculated.

resultsAt a mean of 10.1 years (range 9.1-10.9) following exclusions thirty-seven (69.8%) knees in thirty-one (67.4%) patients (6 bilateral) were available for review. None of the patients required revision surgery. Mean OKS score at 10 years was 37.8. The mean ROM significantly improved from 95° pre-operative to 117.5° at 5 years and 115° at 10 years (p = < 0.001). This equates to a value-added range of motion (VAROM) of 19° at 5 years and 15.6° at 10 years. There was a correlation between OKS and VAROM at 5 and 10 years. Radiological assessment did not reveal any evidence of progressive cement radiolucent lines nor component migration.

conclusionIn this series the Scorpio NRG PS showed 100% 10-year survivorship. We found a significant improvement in ROM and VAROM over time. This was not associated with increased signs of loosening.
