[Value of contrast arthrography in the diagnosis of hemophilic arthropathy]

X-ray semiotics of changes in the roentgen-negative components of the knee joint at different stages of hemophilic arthropathy has been described basing on the study of 46 contrast arthrography ++ of the joint, and their correlation with the results of macroscopic and histological investigations of the tissues removed during surgery. Identification of the character of the damage in the soft-tissue and cartilage components of the joint is particularly important at the early stages of arthropathy, as it enables determining the optimum therapeutic tactics when the data of routine roentgenography give insufficient information, and changes in the bones are limited and, as a rule, reversible.
