Implication

Randomized controlled trial evaluates precision of CT-based analysis for implant migration in knee arthroplasty, indicating sufficient accuracy with varying radiation doses.

Key Points

Precision reached 0.20 mm and 0.17 mm for standard and low radiation doses, respectively, showing minimal difference.
Key outcome was the difference in mean maximum total point motion, with a clinically meaningful threshold of 0.1 mm.
This clinical study evaluated precision through double examinations at different radiation dose levels.
Findings suggest CT-RSA can be reliably used for implant migration analysis in knee arthroplasty.
