Summary. The results of 247 osteotomies at the knee were analysed in 195 patients with Kashin-Beck disease. Since 1983, 37 varus and 210 valgus deformities have been operated on. Supracondylar osteotomy was carried out so that there is a cortical spike in the distal metaphysis which is impacted into the femoral condyle. A U-shaped tibial osteotomy is made 0.5 cm below the growth plate and around the insertion of the patellar ligament. The mechanical axis is corrected and stability obtained by impacting the fragments; internal fixation is not used. Correction of the initial angular deformities was achieved after the osteotomies, and function was improved.

Résumé. Les résultats de 247 ostéotomies du genou sont analysés sur 195 patients atteints de la maladie de Kashin-Beck. La technique d’ostéotomie utilisée se caractérise, au niveau de la métaphyse distale du fémur, par la réalisation d’une section supracondylienne présentant un ergot cortical et au niveau de la métaphyse proximale du tibia par une section respectant l’insertion du ligament rotulien en la contournant distalement. Vu l’absence de matériel de fixation interne ou externe, l’impaction des fragments permet de stabiliser efficacement la correction de l’axe mécanique. Depuis 1983, 37 genu vara et 210 genu valga ont été ostéotomisés. Les résultats présentent la distribution des déformations angulaires initiales et les corrections obtenues après ostéotomie. L’amélioration fonctionelle confirme l’intérêt de cette technique en l’absence de matériel d’ostéosynthèse.
