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

purposeHigh tibial osteotomy (HTO) is a recognised treatment for medial compartment knee arthritis and in recent years has regained popularity. Preoperative planning of wedge opening is based on standing AP radiographs, aiming to deliver the WBL to a desired point. Clinical results can be unpredictable, and this may be due to an inability to deliver the preoperative plan. This study explores the theoretical wedge opening accuracy required to deliver preoperative plans, based on clinical AP radiographs.

methodsA theoretical 2-D model of osteotomy was developed to determine the degree of radiological wedge opening accuracy required to deliver the weight-bearing line to a preoperative target of 62-66 % of the width of the tibial plateau.

resultsThis model suggests that, to deliver the weight-bearing line to the preoperative target on plane radiographs, the theoretical medial wedge must be opened to an accuracy of ±0.9 mm.

conclusionAlthough this study only explores a model of wedge opening based on AP radiographs, with current surgical systems, it is unlikely that the surgeon can achieve this level of accuracy within a real-life surgical setting. Surgical accuracy in HTO is known to be important for both short- and long-term clinical outcomes. This study highlights the need for improved surgical accuracy aids and/or patient stratification to mitigate the effects of surgical errors. LEVEL OF EVIDENCE: II.
