For the purposes of classification, it should be specified whether osteoarthritis (OA) of the
knee is of unknown origin (idiopathic, primary) or is related to a known medical condition or
event (secondary). Clinical criteria for the classification of idiopathic OA of the knee were
developed through a multicenter study group. Comparison diagnoses included rheumatoid
arthritis and other painful conditions of the knee, exclusive of referred or paraarticular pain.

Abstract
For the purposes of classification, it should be specified whether osteoarthritis (OA) of the knee is of unknown origin (idiopathic, primary) or is related to a known medical condition or event (secondary). Clinical criteria for the classification of idiopathic OA of the knee were developed through a multicenter study group. Comparison diagnoses included rheumatoid arthritis and other painful conditions of the knee, exclusive of referred or paraarticular pain. Variables from the medical history, physical examination, laboratory tests, and radiographs were used to develop sets of criteria that serve different investigative purposes. In contrast to prior criteria, these proposed criteria utilize classification trees, or algorithms.
