Biomechanical effects of LCWHTO vs. MOWHTO on medial meniscus posterior root repair: a finite element analysis.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
Whether isolated high tibial osteotomy (HTO) or HTO combined with medial meniscus posterior root (MMPR) repair is the optimal surgical treatment of MMPR tears remains controversial. This study compared the biomechanical effects of isolated HTO versus MMPR repair combined with medial open wedge HTO (MOWHTO) or lateral closed wedge HTO (LCWHTO) using finite element analysis (FEA). In this study, the MRI and CT data of the knee joint were used to create an FEA model. MOWHTO and LCWHTO simulations adjusted the mechanical axis to the Fujisawa point, with MMPR conditions simulated as intact, tear, or repaired. The ankle center was fixed and a 1000 N force was applied to the knee. In the LCWHTO models, the posterior tibial slope (PTS) decreased, whereas it increased in the MOWHTO models. Changes in the PTS following HTO influenced the stress distribution in the MMPR. HTO combined with MMPR repair showed a reduction in the maximum contact stress by 5.4-11.4% and increased contact area by 29.5-41.0% in the medial knee compartment relative to isolated HTO. This study demonstrated that MMPR repair combined with LCWHTO would be more protective against stress loading in the MMPR than MMPR repair combined with MOWHTO or isolated HTO.
