Purpose: Recurrent hemarthrosis is a common clinical entity in hemophiliacs. They not only interfere with daily life but also trigger hemophilic arthropathy. Synovial hypertrophy has a pivot role in hemarthrosis related joint damage and ablation of the synovium prevents further deterioration. Current treatment strategy is to ablate synovium in the early stages in order to prevent progression of the arthropathy. We report a series of hemophilia patients with advanced arthropathy who had been treated with radionuclide synoviorthesis.

Materials and Methods: The patients who had been treated with radionuclide synoviorthesis for either knee or elbow disease between 2002 and 2004 were included in this study. The inclusion criteria were having > 1 hemarthrosis episode per month in the index joint, chronic synovial hypertrophy, advanced degenerative changes of grade III and IV as defined by Arnold-Hilgartner Classification, F8 inhibitor level < 3. The frequency of hemarthrosis, range of motion of the affected joint, pain level that was evaluated by visual analog scale, was recorded during each follow-up. 90Y was used for the synoviorthesis of the knee, whereas 186Re was used for the elbow cases. Patients were screened for radionuclide leak by using a gamma camera following the injection.

Results: Twenty radionuclide synoviorthesis were performed in 14 knees. The average age was 20 (range, 10–31) with an average follow-up of 17 months (range, 3–29). There were 12 severe hemophilia A and 2 severe hemophilia B patients. The frequency of intaarticular bleeding episodes was significantly reduced at the final follow-up (p< 0,05). Although the range of motion and the pain scores were improved, the change was not statistically significant (p> 0,05). Six patients required repeated treatment because of inadequate response. No radioactive material leakage were detected at the draining lymph nodes.

Conclusions: Our results demonstrate that radionuclide synoviorthesis significantly reduces the number of the bleeding episodes even in the knees presenting with advanced arthritis, and increases the quality of life. Although most patients respond to single injection, some patients may require more than one injection, to achieve a satisfactory clinical outcome.
