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

purposeThere are two established techniques for high tibial valgisation osteotomy (HTO): medial open wedge (MOW) and lateral closed wedge (LCW). The aim was to analyze the change of the posterior tibial slope (PTS) caused by HTOs dependent on the technique.

methodsFour hundred fourteen cases of HTOs were analyzed retrospectively. Two hundred seventy-nine osteotomies in 247 patients matched the inclusion criteria and were divided into two treatment groups (MOW/LCW). The PTS was determined on pre- and post-surgical lateral knee X-rays by measuring the proximal posterior tibial angle (PPTA).

resultsOne hundred ninety of the included 279 cases were assigned to the MOW and 89 to the LCW group. The mean PPTA in MOW HTOs was 79.9° ± 32° (68-88°) and in LCW HTOs 80.6° ± 2.6° (74-88°). There was no statistically significant change of the PPTA in the MOW group comparing the pre- and post-surgical values (delta PPTA 0.07° ±2.9° (- 12 to 11°)). In the LCW group, the surgery resulted in a statistically significant reduction (p< 0.001) of the PTS (delta PPTA - 3.09° ± 4.5° (- 12 to 5°)).

conclusionThe important finding of this study is that the thesis of a slope increase in MOW osteotomies found in the literature could not be approved regarding our results as no statistically significant change of PTS in MOW HTOs was observed. The findings support the common thesis that LCW osteotomies cause a slope reduction.
