Standing X-rays of bilateral tibia/ femora and pelvic bones (AP view) at the presentation showing bilateral asymmetric genu valgus, but no reduction of bone density or abnormalities suggestive of rickets in epiphyseal plates (A). Follow-up x-ray of the same projection one year later demonstrating corrective left distal femoral osteotomy with internal fixation screws on the medial aspect of the distal femoral epiphysis and metaphysis. A more pronounced deformity is evident compared to the prior X-ray causing a mild pelvic tilt in the standing position (B)
