title: [Application of interactive virtual reality technique in biomechanical analysis of knee joint stability].
abstract: OBJECTIVE
  To test the feasibility of using interactive virtual reality technique for three-dimensional reconstruction and image segmentation for biomechanical analysis of the knee joint structures.
  
  
  METHODS
  The muscular and fat tissues along with the connective tissues were removed from the knee joint, and the femur and tibia were embedded in polymethacrylate gel. The knee joint was reconstructed with three-dimensional analysis system after calibration of the sequence of the three-dimensional markers attached to the femur and tibia.
  
  
  RESULTS
  The knee joint model was reconstructed and verified by three-dimensional analysis. This model provided information of the motions of the internal and external knee joint structures.
  
  
  CONCLUSIONS
  This method is useful for reconstructing human joints and provides a new and highly efficient experimental method for biomechanical simulation of human joints.
