Engagement-quality mismatch in robot-assisted total knee arthroplasty short videos on TikTok and Bilibili.
Article in Journal of robotic surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Robot-assisted total knee arthroplasty (RA-TKA) is increasingly popular in modern orthopedic surgery, yet the quality and reliability of RA-TKA content on short-video platforms are not well-defined. This cross-sectional study assessed the quality and reliability of short videos related to RA-TKA on TikTok and Bilibili. A systematic search identified the top-ranked 100 videos on each platform, of which 97 videos met the inclusion criteria (68 from TikTok and 29 from Bilibili). The Global Quality Score (GQS) and the DISCERN instrument were utilized to evaluate video quality and reliability. Engagement metrics, uploader characteristics, content categories, and video features were also analyzed. TikTok videos showed higher engagement metrics, while Bilibili videos had better informational quality and reliability, reflected in higher median GQS and DISCERN scores. Videos created by professionals and institutions generally received higher quality scores compared to those by nonprofessionals, though the differences were not always statistically significant. Content focusing on surgical treatment, technology and equipment, and balanced discussions of advantages and limitations showed higher quality and reliability than promotional content. Correlation analysis revealed that engagement metrics were strongly interrelated but did not reliably predict information quality, while longer video duration was associated with higher GQS and DISCERN scores. Videos from professional sources tended to receive higher quality scores, although differences across uploader categories were not consistently statistically significant. These findings suggest a mismatch between popularity and informational value on short-video platforms and suggest that the growing clinical uptake of RA-TKA may not yet be matched by an equally visible supply of structured, balanced public-facing information. Greater professional engagement is warranted to enhance the accurate dissemination of complex robotic orthopedic information in short-video environments.
