Computed tomography-based radiostereometric analysis achieves sufficient precision for femoral implants in total knee arthroplasty: a randomized controlled trial
Randomized controlled trial confirms CT-RSA's precision for femoral implant migration in knee arthroplasty, suggesting comparable outcomes at different radiation doses.
Key Points
Precision for CT-RSA was achieved at 0.20 mm for standard dose and 0.17 mm for low dose, with a p-value of 0.031.
Clinical study assessed femoral component migration in a randomized controlled trial of 50 patients with Tritanium and GMK Sphere implants.
No significant clinical difference in precision between standard and low radiation doses highlights the method's efficacy.
Findings support the use of CT-RSA in clinical settings, making it suitable for migration analysis in total knee arthroplasty.
