Which of the following statements best describes results that have been reported with roentgen stereophotogrammetric analysis (RSA)?
Cemented total hip stems do not migrate.
Well-fixed total hip stems (cemented or cementless) migrate approximately 3 degrees and 5 mm in the first year.
Any early migration (ie, greater than 0 mm less than 6 months after surgery) portends failure of the component.
Migration greater than 1 mm to 2 mm in the first year is associated with a higher risk of loosening.
