Factors influencing results of high tibial osteotomy in gonarthrosis.
Based on our results with high tibia osteotomy for gonarthrosis in 96 knees, the type of primary deformity was found to significantly influence the patient's subjective assessment of the results. Knees with valgus deformity secondary to changes in other joints are not suitable for correction by HTO. Knees with varus deformity exceeding 10 degrees and with roentgenological signs of reduction of the medial tibial condyle are seldom corrected by HTO and the results in these knees are poor. There is a clear correlation between patient's satisfaction with HTO done for gonarthrosis and the correction of femorotibial deformity.
