Effect of radiosynoviorthesis on the progression of arthropathy and haemarthrosis reduction in haemophilic patients.

RS is an effective method to reduce the number of haemarthrosis episodes in chronic synovitis. Moreover, RS can positively affect arthropathy by slowing down its progression. However, the results obtained suggest that arthropathy may be conditioned by the subject's age, regardless of whether or not the joint has undergone RS.
