title: Intra-articular rheumatoid nodule of the knee joint.
abstract: A 44-year-old woman with a long-standing history of classical rheumatoid arthritis had an intra-articular rheumatoid nodule of the knee joint. The history, symptoms, and signs of this case were, however, almost identical to those cases previously reported. This entity has a classic presentation and distinct findings on examination which distinguish it from other intra-articular lesions of the knee.
