Recurrent knee valgus deformity in Ellis-van Creveld syndrome.

Abstract

We report a case of recurrent knee valgus deformity in a patient with Ellis-van Creveld syndrome. Varus osteotomy, distraction osteogenesis, or epiphyseal stapling is one treatment option for valgus malalignment to improve appearance, gait, and function. However, surgical correction of valgus knee deformity by varus osteotomies of the proximal tibia was not maintained postoperatively, necessitating additional varus osteotomies of the distal femur in this case. The main cause of recurrence was attributed to large bony defect of the anterior segment of the proximal tibia, in addition to depression of the lateral tibial plateau.
