1 · What the graph read from 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.

2 · The registry

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

Objectives: Two frequently used surgical interventions for knee joint osteoarthritis include closing wedge high tibial osteotomy (CW-HTO) and opening wedge high tibial osteotomy (OW-HTO). Studies showed that, most to near all cases lead to failure, requiring a total knee arthroplasty (TKA). This systematic review aimed at answering this question: What are the outcomes of TKA following CW-HTO and OW-HTO? Methods: The main electronic databases were searched up to November 2025. Only studies that included comparative arms for both closing-wedge high tibial osteotomy (CW-HTO) and opening-wedge high tibial osteotomy (OW-HTO) were considered for further assessment. The primary outcomes included knee joint function scores, such as the International Knee Society (IKS) score and the Knee Society Score (KSS). A meta-analysis was not feasible because of heterogeneity in the reported data and follow-up periods. The Joanna Briggs Institute (JBI) critical appraisal tool was used to assess the methodological quality of each included study. Results: Of the 6,756 records identified and screened, three comparative clinical studies, including a total of 541 TKA cases, were included in this systematic review. Two studies reported no significant difference in KSS or range of motion after TKA between patients who had previously undergone CW-HTO and those who had undergone OW-HTO. However, one study reported improvements in walking ability in both groups after 80-90 months of follow-up. Post-operative complication rates were comparable between groups (OW-HTO: 12.3% vs. CW-HTO: 8.3%); however, one study noted a significantly higher incidence of specific complications, such as skin necrosis and nerve injury, in the CW-HTO cohort (12% vs. 6%, P<0.05). Intra-operative complications were rare, affecting 2.8% of cases with no significant between-group difference. Conclusion: The limited available evidence precludes definitive conclusions. Current data suggest potential benefits after TKA following either CW-HTO or OW-HTO, including earlier relief of joint loading, shorter recovery time, and improved clinical outcomes, with no significant differences in clinical outcomes and complications between the two HTO techniques.
