title: [Advancement of rotational alignment of femoral prosthesis in total knee arthroplasty].
abstract: OBJECTIVE
  To introduce the concept and clinical applications of rotational alignment of the femoral prosthesis in total knee arthroplasty (TKA) so as to avoided the postoperative complications caused by rotational alignment.
  
  
  METHODS
  The clinical and experimental research literature about rotational alignment of the femoral prosthesis in TKA was extensively reviewed and analyzed.
  
  
  RESULTS
  Femoral prosthesis malrotation can lead to flexion gap unbalanced and undesirable patellar track. Rotation alignment of the femoral prosthesis is defined with radiological and computer assisted technique at pre- and post-operation, which can make the rotation alignment of the femoral prosthesis and the function of the knee favorable.
  
  
  CONCLUSIONS
  In recent years, many surgical skills and new techniques of defining the rotational alignment are developed, and good clinical results are achieved.
