Radiological and clinical outcomes of open-wedge high tibial osteotomy with and without grafting.
Article in The Journal of international medical research, 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
ObjectiveThe role of autologous bone grafting in medial open-wedge high tibial osteotomy remains controversial. This study compares the clinical and radiological outcomes of open-wedge high tibial osteotomy performed with and without autologous bone grafting.MethodsThis nonrandomized two-center prospective cohort study recruited 73 patients who underwent open-wedge high tibial osteotomy. The radiological union status was assessed using a modified van Hemert scoring system and modified Radiological Union Scale for Tibia score. Clinical measures included the International Knee Society Score, clinical union time, and postoperative complications with a minimum 1-year follow-up.ResultsRadiological union at 1 year was significantly higher in the graft group, with 80.0% achieving complete union across all five zones compared with 44.7% in the no-graft group (p = 0.002). However, no significant differences were observed in the postoperative International Knee Society Scores (168 ± 15.7 vs. 168 ± 14.6; p = 0.920), hip-knee-ankle angle correction (181° in both groups; p = 0.687), or clinical union time (10.2 ± 1.77 vs. 10.7 ± 1.35 weeks; p = 0.133).ConclusionAutologous iliac crest bone grafting significantly improved the radiological healing in open-wedge high tibial osteotomy without increasing the incidence of complications.
