Unicompartmental Knee Arthroplasty Offers More Natural Feeling Joints Compared with Total Knee Arthroplasty: A Systematic Review and Meta-Analysis.
Review in JB & JS open access. 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
Background: Unicompartmental knee arthroplasty (UKA) preserves healthy cartilage and may provide a more "natural-feeling" joint compared with total knee arthroplasty (TKA). The Forgotten Joint Score (FJS) is increasingly used to assess joint awareness. We aimed to systematically compare FJS outcomes in patients undergoing UKA versus TKA. Methods: Following Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, we searched PubMed, Embase, Scopus, and Web of Science. We included studies reporting FJS in UKA vs. TKA, assessed risk of bias using the Newcastle-Ottawa Scale, and Cochrane RoB-2, and conducted random-effects meta-analyses to calculate pooled mean differences (MD), and sensitivity analyses were performed to assess the robustness of the findings. Results: Ninteen studies (16 cohort, 3 randomized clinical trials; 4,500 knees) were included. Overall, the pooled MD in FJS favored UKA by 8.45 points (95% CI: 6.03-10.88; p < 0.001), indicating lower joint awareness. However, heterogeneity was high (I Conclusion: Despite substantial heterogeneity, these findings suggest that UKA may offer superior joint awareness compared with TKA. Level of Evidence: Level III.
