Similar secondary patellar resurfacing but higher tibial revision risk with posterior stabilized versus medial pivot total knee arthroplasty: A registry analysis.
Article in Journal of experimental orthopaedics, 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
Purpose: Patellar complications are among the most frequent causes of revision after primary total knee arthroplasty (TKA). The primary study objective is to compare the rate of secondary patellar resurfacing between medial pivot (MP) and posterior stabilized (PS) designs in TKAs. Methods: Analysis of the Swiss national knee joint registry, including TKAs without patellar resurfacing at index surgery performed between 2012 and 2023. Only TKAs with MP and PS designs featuring cemented femoral and tibial components were included. Time-to-event analysis was performed using Kaplan-Meier curves and Cox proportional hazards regression. Multivariable models adjusted for age, sex and BMI. Results: A total of 32,540 TKAs were included in the final analysis. Component revision was performed in 5.8% ( Conclusion: No difference in secondary patellar resurfacing rates was observed between MP and PS designs in primary TKA. However, PS designs are associated with increased tibial revision risk compared to MP designs. Level of Evidence: Level III.
