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

background and purposeMedial opening wedge high tibial osteotomy (MOWHTO) is a well-accepted procedure, which has been widely used for pain relief and varus deformity correction in the osteoarthritic (OA) knee, especially in the young patient. However, in the elderly patient, the efficacy of this procedure is still unknown. Therefore, this study aims to evaluate the survivorship of MOWHTO in elderly patients as the primary outcome. The secondary outcome is to evaluate the loss of correction angle that is the common complication after MOWTHO. MATERIALS AND

methodA retrospective study of 50 elderly patients (≥ 60 years) was conducted to track survivorship of MOWHTO. All patients were diagnosed with varus OA knee and underwent MOWHTO at our institute. The patients who had previous knee surgery or incomplete data were excluded. Medical records and radiographs of eligible patients were reviewed for recruiting the data. Survivorship of MOWHTO was analyzed using Kaplan-Meier curves. The starting point was the time of operation and the end point was the time of subsequent TKA. The loss of correction angle was defined as the change of medial proximal tibial angle (MPTA) between three months and one year post-operatively.

resultsThe mean age of patients was 66 ± 5.0 years. The majority of patients were female (74%). The mean correction angle was 10.6 ± 3.6 degrees. The union rate of osteotomy site was 100%. In survival analysis, the median follow-up time was 6.0 ± 3.0 years. Two patients required subsequent conversions to TKA. The survivorship of MOWHTO at four years was 95.5% (95%CI, 96.0 to 98.0). For radiographic assessment, the loss of correction angle was 1.0 ± 0.5 degrees at one year post-operatively.

conclusionThis study proved that MOWHTO in patient ≥60 years had good mid-term survivorship with acceptable complications. This procedure can be the alternative option for the treatment of varus OA knee in the elderly.
