The synovial membrane of normal and experimentally induced hemarthrotic knee joints of the rabbit was studied using the scanning electron microscope. In a normal synovial membrane, three kinds of villi are recognized: a) macrovilli observed easily with low magnification stereomicroscopy, b) medium size villi corresponding to protruded synovial lining cells and large cytoplasmic processes and c) microvilli equivalent to fine cytoplasmic processes. Early reactions of the synovial surface to the blood injection are seen in medium size villi and microvilli, which increase in number and size. Subsequently hypertrophy and hyperplasia of macrovilli take place. By light microscopy of the synovial fluid, phagocytosed erythrocytes and numerous vacuoles are found in the cytoplasm of detached synovial cells and monocytes. The injected blood seems to be removed in 1 week. Regressive changes of the synovial membrane begin 2 weeks after the blood injection and they are conspicuous 4 weeks post injection. Medium size villi are flattened and microvilli are decreased in number and height at that time.
