Evaluation of posterolateral tibial plateau fracture treatment using a modified anterolateral bimuscular approach: a technical note and retrospective study.
Article in BMC surgery, 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
backgroundThe treatment of posterolateral tibial plateau fractures(PTPF) is challenging, and 3D printing technology can assist in their management.
objectiveComparative efficacy of modified anterolateral approach versus traditional anterolateral approach in open reduction and internal fixation for posterolateral tibial plateau fractures.
methodsForty-seven patients with PTPF treated at the First Affiliated Hospital of Xinjiang Medical University between February 2018 and May 2022 were analyzed. Group A (n = 24) underwent a modified anterolateral approach, and Group B (n = 23) a traditional anterolateral approach. We compared intraoperative blood loss, operative time, fixation method, fracture healing, and complications. Knee function was assessed with the Rasmussen knee score, and radiographic reduction with the Rasmussen radiographic score.
resultsAll 47 patients were followed up for more than one year postsurgery. All fractures achieved satisfactory union, with no vascular injury, nerve injury, or wound infection observed. The mean duration of surgery in Group A was significantly lower than those in Group B. There was a significant difference in the mean Rasmussen function scores between Group A and Group B. The average Rasmussen radiology scores in Group A were significantly greater than those in Group B. No significant difference was found in the mean time required for bone union and amount of intraoperative blood loss between the two groups.
conclusionIntegrating 3D printing technology with different surgical approaches for PTPF management shows favorable outcomes and enhances postoperative safety. The modified anterolateral approach leads to reduced exposure time, less blood loss, and better knee function recovery than the traditional approach. It is recommended to use the modified anterolateral approach at the time of treating posterior lateral tibial plateau fractures.
