Intraoperative fluoroscopically assessment underestimates the posterior tibial slope in open-wedge high tibial osteotomy.
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. Cited by 2 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
Purpose: To compare intraoperative and postoperative posterior tibial slope (PTS) measurements and determine whether unintended postoperative changes occur relative to preoperative values. Methods: A total of 79 patients (81 knees) underwent open-wedge high tibial osteotomy (owHTO) using patient-specific instrumentation (PSI) for varus malalignment were included. PTS was assessed pre, intra and postoperatively on short lateral knee radiographs using standardised calibrated software. The hip-knee-ankle angle (HKA) and the medial proximal tibia angle (MPTA) were measured pre and postoperatively on weight-bearing long leg radiographs (LLR). Results: Preoperative (10.3° [7.3-11.7°]) and intraoperative (9.1° [6.7-11.2°]) PTS measurements were significantly lower than postoperative (10.8° [8.5-13.3°]) values ( Conclusion: Intraoperative PTS measurements significantly underestimated postoperative PTS, by a mean of 1.8°, indicating that visual intraoperative assessment based on fluoroscopy should be interpreted with caution when used to evaluate postoperative PTS. Level of Evidence: Level IV.
