[Synoviorthesis of the knee joint with 32P-chromic phosphate (author's transl)]

32P-CrPO4 in colloid form has been used for radiosynoviorthesis. There were no acute or subacute side reactions observed. The therapy results were equal to those following 90Y colloid application: 60% very good to good results after 6 months. The substance can be kept on stock since it has a relatively long shelf-life. The cost reduction and the simplification of treatment planning have proved to be the most important advantages of 32P-CrPO4.
