Axial deviations of the knee with secondary arthrosis. Correction by high osteotomy of the tibia and fibula.

The authors describe a surgical technique for high tibio-fibular osteotomy used eighty seven times to correct varus or valgus deviations causing arthrosis of the knee. Osteotomy of the tibia is carried out above the tibial tuberosity. Fixation is by two nails with a compression device. This allows immediate movement of the knee, thereby preventing stiffness. After forty five days the osteotomy is usually consolidated. Of the complications, only the neuro-muscular type is of importance and the possible causes of this are discussed. The overall results are good and the technique described has proved to be effective in the treatment of mechanical arthrosis of the knee.
