[Opaque arthrography in the evaluation of gonarthrosis]

The Authors have studied, by means of the arthrographic technique, 24 cases of knee osteoarthrosis in various clinical phases. In the diagnosis of the early phases of the disease, this technique as been helpful in showing alterations, as the widening of the intercartilaginous space, the irregularities of synovial outlines, the enlargement of the normal popliteal space, which common techniques, unusually cannot display. The assay is not needed in the most advanced phases of the disease but it could here as well supply further diagnostic data (i.e. popliteal cyst, etc.). Therefore the authors suggest the arthrographic technique as a complementary assay to the roentgenological one, as well as an elective technique in the early phases of the knee osteoarthrosis.
