[Septic arthritis in newborns and infants--the value of arthrography in diagnosis of post-inflammatory knee defects].

Double-contrast arthrography of the knee was performed on 16 knees in 14 children, who after septic arthritis of the knee in newborn and neonatal period, showed defects of the secondary ossification centers of the femur or tibia on plain radiographs. Cartilaginous epiphysis, normal in shape and volume, was present in 11 cases. In 3 cases cartilaginous epiphysis of the femur was present, but had diminished size.
