The effect of radiation synovectomy with phosphorus-32 on the pain and swelling in 31 RA patients with resistant monoarthritis of the knee.

In our study, we demonstrated that pain, tenderness, effusion, and ROM are improved after radiation synovectomy with phosphorus-32. We also showed that there was no serious adverse effect like infection and necrosis. However, more than half of our patients experienced pain and swelling of injection site at the time of administration. Key points • We demonstrated the efficacy of radiation synovectomy as a medication for monoarthritis. • The results of our study can lead to a bigger clinical trial to assess the benefits and adverse effects of radiation synovectomy in comparison to treatment with local or systemic corticosteroids.
