Radiosynovectomy using yttrium-90, phosphorus-32 or rhenium-188 radiocolloids versus corticoid instillation for rheumatoid arthritis of the knee.
Radiosynovectomy (RSO) is widely used in rheumatoid arthritis (RA). Commercially available radiopharmaceuticals are costly, and therefore new agents may be of interest. Radiocolloids labelled with less costly and more accessible radionuclides are of interest to developing countries. We investigated the efficacy of different formulations in RA. ⋯ Therapeutic efficacy of RSO for RA of the knee applying either P-32, Re-188 or Y-90 provides comparable results. Pain relief by RSO is longer lasting as compared to corticosteroid instillation.
