In this systematic review , we determined how well studies have adhered to these guidelines .
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
