title: Cemented versus uncemented femoral components in total knee arthroplasty.
abstract: OBJECTIVE
  The aim of this study is to analyse the influence of femoral cement on clinical and radiological results after total knee arthroplasty.
  
  
  METHODS
  Preoperatively 130 patients were randomly assigned to treatment in either the Cement Group or the Hybrid Group. The International Knee Society scores, femoral radiolucent lines and bone transparencies were compared.
  
  
  RESULTS
  There were no significant differences concerning postoperative knee and function scores. We observed a significant difference in radiolucent lines (Cement Group, 24%; Hybrid Group, 2%; P < 0.001) as well as bone transparencies (Cement Group, 21%; Hybrid Group, 62%; P < 0.001). All radiolucent lines measured less than 2 mm in width.
  
  
  CONCLUSIONS
  Cementing the femoral component of a total knee arthroplasty does not appear to influence the clinical results. A longer follow-up period is required to determine the influence of radiological findings on final outcome.
