Augmented Reality With Dynamic Anatomy Modelling for Knee Arthroscopy.
Article in Healthcare technology letters. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Research on augmented reality (AR) for knee arthroscopy has not adequately focused on knee flexion during surgery. To overcome major AR errors caused by knee movement, this study presents an association model between the finite-element models of the knee surface and bones to enable dynamic anatomy modelling. The association model allows the displacement of the knee surface elements and the reaction force of the bone elements to interact with each other. During knee flexion, the real-time shape of the knee is captured with a colour and depth camera, and the association model deforms accordingly from the extension to the flexion state. The proposed model was evaluated using computed tomography data from the knees of six participants. The results showed that the association model successfully compensates for the movement of the femur and tibia within an error margin of only 3.85 mm around the drilling area. The proposed model could therefore enable effective AR-based surgical navigation during knee surgeries.
