Return to sport outcomes after inverted V-shaped (IV) high tibial osteotomy were comparable to those after medial opening-wedge high tibial osteotomy, even though the IV cohort had more severe preoperative disease.

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

Purpose: The primary aim was to compare return to sport (RTS) outcomes following inverted V-shaped high tibial osteotomy (IV-HTO) versus medial opening-wedge (OW)-HTO for medial knee osteoarthritis (OA). The secondary aim was to compare patient-reported outcomes and radiographic parameters between the procedures. Methods: This retrospective cohort study included patients who underwent HTO for medial knee OA between 2017 and 2022. Inclusion criteria were preoperative sports participation and 2-year follow-up. Patients were allocated to IV-HTO (IV group) or OW-HTO (OW group) according to indications based on the planned correction angle and patellofemoral OA grade. Outcomes were assessed preoperatively and at 2 years. Between-group comparisons used appropriate parametric/nonparametric tests, with Results: A total of 107 patients were analysed (IV group: 54 patients; OW group: 53 patients). Mean age was 58.4 years, body mass index (BMI) 25.6 kg/m Conclusions: IV-HTO achieved RTS and patient-reported outcomes comparable to OW-HTO at 2 years in patients with more severe preoperative disease. Level of Evidence: Level III, retrospective comparative study.
