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 .
Inferior performance of Boneloc bone cement in total knee arthroplasty: a prospective randomized study comparing Boneloc with Palacos using radiostereometry (RSA) in 19 patients.
We compared Boneloc bone cement with conventional cement ( Palacos ) in fixating the tibial component during 2 - 5 years in 19 patients with gonarthrosis undergoing total knee arthroplasty in a prospect i ve r and omized study .  Boneloc displayed significantly larger migration , subsidence and lift-off than Palacos . The difference was identifiable already within 3 months postoperatively , but became significant at 12 months . In the Boneloc group , all components showed subsidence of the posterior part and lift-off of the anterior part of the tibial component , whereas in the Palacos group , the locations of subsidence and lift-off were evenly distributed about the edge of the implant . At 5 years , both Boneloc knees so far investigated were clinical failures with high migration rates . We conclude that , even in total knee arthroplasty , there is a substantial risk that Boneloc leads to inferior clinical results , but later than in hip replacements
