The authors present the study of 53 synovial membranes using histology and morphometry. The sinovyal menbrane was collected from ostheoarthritic knees which presented lymphoscintigraphic abnormalities. The morphometric study showed inflammatory infiltrate, congestive vessels and fibrosis. Articular lymphoscintigraphy, with 99mTc labelled dextran, demonstrated that at 24 hours the tracer disappeared more slowly from the abnormal joint but accumulated more intensely in regional lymph nodes on the diseased side. Statistical analysis of the morphometric and lymphoscintigraphic data shows a significant correlation between lymphatic dysfunction and the synovial menbrane fibrosis. There is no significant correlation between other morphometric data (vessels and inflammatory infiltrate) and articular lymphoscintigraphic results.
