    Abstract:
    Amyloid arthropathy is an important complication of long-term hemodialysis. This condition may lead to destructive bone lesions and to severe functional impairment. We studied with sonography of both knees 32 long-term dialysis patients (mean dialytic age: 69.7 months), whose 7 were carrying palpable joint swellings. In 29/32 patients, ultrasound scans were associated with knee X-rays films, patellar views included. In one case, opaque arthrography was performed too. Sonography demonstrated the presence of fluid collections within the articular space and the synovial cavities in 19/32 patients (59%). Their content was transonic or mildly hypoechoic. X-ray films were positive for amyloid bone involvement in 19/29 cases (66%), with intra-osseous cysts and cortical erosions. There was a good general agreement between the results obtained with the two techniques: therefore, in some cases only one examination was positive. Sonography is proposed, in association with standard X-ray films, as a simple and reliable method for the diagnosis of articular amyloidosis in dialysis patients and for the follow-up of this disease.
