Cemented and uncemented tibial components had different migration patterns .
For cemented tibial components there was no difference in migration between all-poly and metal-backed components , between mobile bearing and fixed bearing , between cruciate retaining and posterior stabilized .
Furthermore , no difference existed between TKR measured with model-based RSA or marker-based RSA methods .
For uncemented TKR there was some variation in migration with the highest migration for uncoated TKR .
Interpretation - The results from this meta- analysis on  RSA migration of TKR  are in line with both the survival analyses results from joint registries of these TKRs as well as revision rates results from meta-analyses , thus providing further proof for the association between early migration and late revision for loosening .
Purpose - We performed a systematic review and meta-analyses to evaluate the early and long-term migration patterns of  tibial components of TKR of all known RSA studies .
VersaBond bone cement prospective randomized study of the clinical properties of a new bone cement in total knee replacement.
VersaBond is a newly developed bone cement . To investigate its clinical performance , VersaBond was compared to Palacos R in a prospect i ve r and omized study in total knee replacement . Fifty-nine patients ( 61 knees ) undergoing total knee replacement were r and omized 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
