[Indications for arthrodesis of the knee joint in modern orthopedics].
BACKGROUND
Indication for arthrodesis of the knee joint is nowadays most frequently failure of a total endoprosthesis, usually septic. A less frequent indication is purulent gonitis, frequently after corticoid administration, the condition after a complicated intraarticular fracture with subsequent arthritis or oncological disease of the bones in the area of the knee joint.


METHODS
In the course of 2000 to 2002 at the authors' department 15 arthrodeses were implanted. In three cases the indication for arthrodesis was purulent gonitis, in three cases the condition after an open articular injury associated with infectious complications and in the remaining nine cases failure of an endoprosthesis of the knee, incl. seven caused by infection. The patients were three men and 12 women, mean age 64 years (30-75 years). For stabilization of the arthrodesis 9x external fixation was used, 5x plates and 1x intramedullary osteosynthesis.


RESULTS
In all cases consolidation of the arthrodesis was achieved. In one case the external fixation had to be replaced by a system of two fixation devices and in one case correction of the axial position of the extremity was made. The presence of external fixation was perceived negatively in particular by female patients.


CONCLUSIONS
Plate osteosynthesis and the use of external fixation devices are relatively quick, cheap and considerate methods of arthrodesis. External fixation must be used in acute virulent infections while plate osteosynthesis can be indicated in its absence. The characteristic of intramedullary fixation is similar, however special nails used for arthrodesis of the knee are several times more expensive than the previous types of stabilization. The advantage is the possibility to use a massive bone graft to fill the defect.
