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 .
Fixation of the tibial component using CMW-1 or Palacos bone cement with gentamicin: Similar outcome in a randomized radiostereometric study of 51 total knee arthroplasties
We studied CMW-1 bone cement with gentamicin in the laboratory and in a r and omized clinical study . Palacos bone cement containing gentamicin was used as the control . In the pre clinical evaluation , the CMW cement had slightly less mechanical strength . In the clinical study , 51 patients ( 51 knees ) operated on with total knee arthroplasty were studied for 2 years . We used radiostereometric analysis to measure migration of the tibial components , r and omized to fixation with either of the two types of cement . The extent and pattern of migration were similar in both groups , and we found no differences in the number , size and extent of radiolucent lines or clinical outcome . No complications occurred . Our findings suggest a need for more studies of CMW-1 bone cement containing gentamicin in a larger cohort of patients
