Accuracy of matching tibial slope in manual kinematically aligned total knee arthroplasty.
Article in Journal of orthopaedics, 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: Reproduction of the posterior tibial slope (PTS) during total knee arthroplasty (TKA) improves patient outcomes and minimizes complications including subsidence, polyethylene wear, and instability. The use of imaging has been previously studied as a way of measuring PTS angle and its association with surgical outcomes. There is a lack of literature on the accuracy of matching PTS during manual kinematically aligned (KA) TKA. Methods: This is a retrospective study including 299 primary manual KA TKAs between October 2021 and August 2024 by a single surgeon. The primary outcome was comparison of pre-operative and post-operative PTS angles. Measurements were performed on lateral radiographs as the angle between the tangent line of the tibial plateau and a line perpendicular to the tibial shaft axis. Results: The average pre-operative tibial slope was 10.3 Conclusion: In this study, we found a significant difference in pre-operative and post-operative tibial slope angle on radiographic measurements following manual KA TKA.
