The effectiveness of a second intra-articular injection of yttrium-90 colloid was studied in 30 patients with persistent synovitis of the knee. All had responded poorly to a first injection of yttrium-90 yet seemed likely to benefit from this therapy. With a minimum review period of 6 months complete remission of synovitis was obtained in 20%, while 63% gained symptomatic relief, with some reduction of synovitis. No improvement occurred in 17%, and in this group generalised disease activity was more apparent.
对30例膝关节持续性滑膜炎患者进行了第二次关节腔内注射钇-90胶体的疗效研究。所有患者对首次注射钇-90的反应均不佳，但似乎可能从该治疗中获益。在至少6个月的随访期后，20%的患者滑膜炎完全缓解，63%的患者症状缓解，滑膜炎有所减轻。17%的患者无改善，且该组患者全身疾病活动更为明显。
