title: Elevation of the medical plateau of the tibia in the treatment of Blount disease.
abstract: Seven children, between ten and thirteen years old, had elevation of the medial plateau of the tibia for correction of severe varus deformity secondary to Blount disease. The deformity was severe (grade V or VI according to the system of Langenskiöld and Riska) in all patients; the average preoperative varus deformity, determined by the angle formed by the femoral shaft and the tibial shaft, was 25 degrees. The goal of the operation was restoration of a more normal configuration of the articular surface of the proximal end of the tibia. This was accomplished by direct elevation of the depressed medial tibial plateau. All patients had an osteotomy to correct the alignment of the tibia. The osteotomy was performed concomitant with the elevation of the plateau in three patients, before the elevation in three, and after the elevation in one patient. Four patients had a concomitant osteotomy of the femur to align the knee joint parallel to the floor. The results were good in five patients and fair in two.
