Genu valgum secondary to focal fibrocartilaginous dysplasia of the distal femur

J Pediatr Orthop. 2004 Jul-Aug;24(4):408-13. doi: 10.1097/00004694-200407000-00012.


We report a case of unilateral genu valgum secondary to focal fibrocartilaginous dysplasia (FFCD) isolated in the posterolateral cortex of the distal femur. This case is the first incidence of a discrete fibrous band occurring in conjunction with a FFCD lesion in the distal posterolateral femur treated with excision of the tether and the overlying periosteum with curettage of the cortical focal fibrocartilaginous defect. Treatment was considered successful with gradual resolution of the 30 degrees valgus deformity over 24 months, and we avoided the necessity of corrective osteotomy and its associated risks. To our knowledge, resolution of genu valgum secondary to FFCD in the distal posterolateral femur after curettage has not been previously described in the literature.
