Learning curve of augmented reality surgical application for reverse shoulder arthroplasty.
Article in Archives of orthopaedic and trauma surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundAccurate positioning of the glenoid component in reverse total shoulder arthroplasty is important since it reduces prosthesis-related complications. Conventional instrumentation is still the gold standard. However, patient-specific instrumentation using 3-D printed guides, as well as computer-assisted navigation, is gaining more and more importance. Augmented reality has been established to enable the surgeon to have more precision in the positioning and inclination of the glenoid component. A new technique called "NextAR" (©Medacta) supports the surgeon during operation by guidance on bone preparation, instrument navigation, and implant placement, using virtual reality goggles or displays. The aim of this study was to determine a learning curve for reversed total shoulder arthroplasty by a high-volume single shoulder surgeon using the NextAR system.
methodsWe performed retrospective data analysis of the first 20 cases of one high-volume single shoulder surgeon performing reversed total shoulder arthroplasty using the NextAR system. Parameters such as anesthesia time, surgical time, length of hospital stay, classification of the American Society of Anesthesiologists, body mass index, intraoperative blood loss, and complications were analyzed.
resultsWe found significant decreases in measures like surgery time (p = 0,001), amount of blood loss during surgery (p = 0,005), and anesthesia time (p = 0,08). A remarkable turning point of blood loss occurs within the fifteenth surgery. A significant reduction of the operation time is shown at the fourteenth operation. Looking at blood loss and operation time together using a standardized cumulative curve, a significant reduction of the cumulative score is found within the fifteenth surgery.
conclusionSignificance was found in surgery time as well as in the amount of blood loss. However, these results may not be generalizable since they depend on further conditions. Future studies could provide information about other outcome parameters and learning curves of several surgeons performing reversed total shoulder arthroplasty with augmented reality applications.
