Two regimens to immobilise the knee after injection were compared in patients receiving intra-articular yttrium-90 for persistent synovitis of the knee, the patients being randomly allocated to receive either complete bed rest or full mobilisation with the affected knee in a firm splint. There was no difference in the percentage of the radioisotope retained in the knee or in that taken up by other tissues between the two regimens. It is concluded that after intra-articular injections of yttrium-90 strict bed rest in hospital is unnecessary.
在接受关节腔内注射钇-90治疗膝关节持续性滑膜炎的患者中，比较了注射后两种固定膝关节的方案，患者被随机分配接受完全卧床休息或用坚固夹板固定患膝并完全活动。两种方案在膝关节中保留的放射性同位素百分比或其他组织摄取的放射性同位素百分比方面没有差异。得出的结论是，关节腔内注射钇-90后，无需在医院严格卧床休息。
