Focal fibrocartilaginous dysplasia(FFCD) is an uncommon, benign condition associated with unilateral tibia vara among young children. FFCD has a typical plain radiographic finding, which has a concave radiolucent defect in the metadiaphyseal junction of medial aspect of the proximal tibia. The varus deformity occurs at the site of the lesion. Spontaneous remodeling and resolution of bony defect may be expected, but the corrective osteotomy may also be needed in some cases. The authors described a case of unilateral tibia vara caused by FFCD, diagnosed by excisional biopsy and treated with dome-shaped proximal tibial osteotomy and bone graft.
