Femoral and Patellar Radiographic Metrics Are Improved With Robotic-Assisted Total Knee Arthroplasty.
Article in Arthroplasty today, 2025. 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
Background: Although robotic technology enhanced surgery does not directly address the patella, its associated improvement in knee reconstruction and flexion balance may result in improved patellar function and radiographs. In this retrospective observational analysis, we aimed to 1) compare patellar and femoral radiographic metrics between robotic-assisted and conventional total knee arthroplasty (RA-TKA and C-TKA) and 2) assess the correlation between these radiographic metrics and postoperative patient-reported outcomes in the RA-TKA cohort. Methods: Fifty RA-TKAs were compared with 50 C-TKAs at an average 2.8 years of follow-up. Age, gender, body mass index, type of arthritis, preoperative range of motion, preoperative pain localization, type of implant, precut patellar thickness at the expected location of the apex, postcut patellar thickness at the same location, patellar button thickness, and length of stay were compared, along with patient reported outcome measures. Descriptive stats, Results: A significantly lower postoperative patellar displacement (1.92 vs 3.16; Conclusions: RA-TKA had better patellofemoral metrics than conventional TKA. The RA-TKA group showed a significant improvement in patellar displacement and posterior femoral overstuffing, and lower incidence of patellar tilt >5 degrees compared to the C-TKA cohort.
