title: VersaBond bone cement prospective randomized study of the clinical properties of a new bone cement in total knee replacement.
abstract: VersaBond is a newly developed bone cement. To investigate its clinical performance, VersaBond was compared to Palacos R in a prospective randomized study in total knee replacement. Fifty-nine patients (61 knees) undergoing total knee replacement were randomized to either VersaBond or Palacos R bone cement and followed for 24 months using radiostereometric analysis (RSA). Up to 2 years there were no significant differences in clinical performance between the two cements. The mean/median values for implant migration were very similar for the two bone cements, as were the dispersion, and distribution of outliers. Also the proportion "stable" and "continuously migrating" implants was similar between the two cements. The result of this study indicates that VersaBond bone cement will perform at least equally as well as Palacos R in total knee replacement as regards as aseptic loosening.
