Radiologic classification of knee joint destruction in juvenile chronic arthritis
Abstract:
A new radiologic classification of juvenile chronic arthritis (JCA) of the knee joint is presented. Osteoporosis, epiphyseal enlargement, erosions, subchondral cyst formation and deformity of the joint surfaces are expressed in terms of a score. No attention is paid to the joint space or soft tissues. Thirty knee joints in 15 patients with JCA were evaluated according to the radiologic classification. There was a good correlation between the radiologic score and the clinical findings. The inter- and intraobserver variation was low. The classification system is proposed as a valuable tool for measuring the degree of knee joint destruction in evaluation of the natural course or results of treatment in JCA.

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
