Does Augmented Reality-based Portable Navigation System Improve the Accuracy of Acetabular Component Orientation During THA?

CONCLUSIONS: This system yielded no differences in acetabular anteversion accuracy, and no clinically important differences in acetabular inclination. Therefore, at this time we cannot recommend this device as its costs and risks cannot be justified based on the absence of a clinically meaningful difference in cup placement accuracy. Although we detected no complications, this was a small series, and this approach adds both surgical time and pins in the ilium.
LEVEL OF EVIDENCE: Level I, therapeutic study.
