Evaluation of migration analysis with AI-based CT-RSA and preoperative 3D-planning in total hip arthroplasty

AI-based CT-RSA demonstrated accuracy comparable to MBRSA, with slightly improved precision and reduced user-dependence. The same system also provided an accurate and predictable preoperative implant plan.
