Intra-rater and inter-rater reliability of robotic arthrometer DYNEELAX®.
Article in Journal of experimental orthopaedics, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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.
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
Purpose: The purpose of our study was to test the intra-rater and inter-rater reliability of the DYNEELAX® arthrometer in healthy subjects. Since rotational laxity will be measured for the first time in humans, indications for normative values will also be presented. Methods: Knee anterior laxity and rotational laxity using a DYNEELAX® arthrometer were assessed in 73 subjects (39 females and 34 males). An intraclass correlation coefficient was calculated to evaluate the intra-rater and inter-rater reliability of the DYNEELAX®. Results: An intraclass correlation coefficient for intra-rater reliability ranges from 0.631 (95% confidence interval; [CI]: 0.47-0.75) to 0.699 (95% CI: 0.56-0.80) and from 0.916 (95% CI: 0.87-0.95) to 0.94 (95% CI: 0.91-0.96) for anterior knee laxity and rotational knee laxity, respectively. An intraclass correlation coefficient for inter-rater reliability ranges from 0.578 (95% CI: 0.40-0.71) to 0.646 (95% CI: 0.44-0.78) and from 0.822 (95% CI: 0.57-0.91) to 0.933 (95% CI: 0.89-0.96) for anterior knee laxity and rotational knee laxity, respectively. Conclusions: The DYNEELAX® arthrometer has good to excellent intra-rater and inter-rater reliability for rotational knee laxity and moderate intra-rater reliability for anterior knee laxity in healthy subjects. Future studies should investigate the clinical significance of anterior and rotational laxity measured with the DYNEELAX® arthrometer in patients with knee pathology, as both laxities are critical for assessing the integrity of the intra-articular structures of the knee in clinical practice. Level of evidence: Level IV.
