Abstract
A new radiographic grading system for evaluation of juvenile rheumatoid arthritis (JRA) for the knee is presented. The classification is based on known arthritic criteria in childhood. Joints with erosion are given a higher score than growth disturbances alone. Signs of osteoarthrosis including joint space narrowing were excluded from the classification. The femorotibial and patello-femoral joints are assessed together. Verbal definitions are used for the classification, but, regarding the erosions, standard reference films are used. The intra- and inter-observer variations of the method were low. (P <0.01)
