Spontaneous resolution of angular deformity of the distal femur in focal fibrocartilaginous dysplasia: a case report.
Focal fibrocartilaginous dysplasia (FFCD) is a rare cause of angular deformities around the knee in children. The FFCD lesion most commonly affects the proximal tibia and less commonly the distal femur. We report a case of distal femoral varus deformity secondary to FFCD. Spontaneous resolution of the deformity occurred during a 7-year period. Previous reported femoral cases showed progressive deformity and required treatment with soft-tissue releases with or without osteotomy. This is the first reported femoral case of spontaneous resolution of angular deformity secondary to FFCD. We recommend a trial of observation for distal femoral lesions before surgical intervention.
