Radiostereometry in Knee Arthroplasty

Radiostereometry (Model Based RSA) in the Assessment of Knee Prosthesis Outcome:a Prospective,Pilot,Single-center Study.

The innovative aspect of this research is the possibility of combining the data collected with radiostereometric model based Radiostereometry with the data collected through the Galeazzi Institute Registry.This opens the prospect of an earlier identification of patients undergoing prosthetic knee replacement with initial aseptic loosening.
