Comparing Simulation Approaches Used in Finite Element Modelling of a Medial Opening Wedge High Tibial Osteotomy.

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.
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
purposeMedial opening wedge high tibial osteotomy is a surgical procedure intended to relieve the symptoms of osteoarthritis in the medial compartment of the knee by addressing malalignment within the structures of the knee. In previous studies, the osteotomy cut and wedge opening in a Medial opening wedge high tibial osteotomy finite element model has been represented using either one of two techniques, which we define herein as wedge opening and wedge removal approaches. The purpose of this study is to determine whether the wedge removal for a medial opening wedge high tibial osteotomy finite element modelling study predicts accurate stresses and strains in the plate, screw, and throughout the proximal tibia, in comparison to the wedge opening.
methodsSeven tibia models were reconstructed from CT scans of seven cadaveric specimen. Two sets of models were created from the same set of specimens to create the wedge opening (n = 7) and wedge removal (n = 7) dataset.
resultsA statistically significant difference in the mean plate stresses, screw stresses, and stresses in the tibia at the region around the apex of the osteotomy were found with the wedge removal, resulting in 4-59% greater stresses.
conclusionThe wedge removal is not an accurate representation of a medial opening wedge high tibial osteotomy with respect to the wedge opening. Selecting the appropriate modelling method that best represents the clinical scenario is the first crucial step in creating a representative finite element model.
