We have reviewed the results of 99mtech-netium-methylene diphosphonate (Tc-MDP) bone scintigrams performed on patients following total knee arthroplasty. In addition, 67gallium (Ga) citrate scintigrams were carried out sequentially on 29 patients. Three groups of patients were identified: those with asymptomatic knees (undergoing scans for other reasons); those with aseptic or septic loosening; and those with pain without radiologic evidence of loosening. There was good correlation between the results of the scans and the final outcome. We conclude that sequential 99mTc-MDP and 67Ga citrate scintigrams are useful for demonstrating the presence of aseptic and septic loosening in knee prostheses, and pain with a normal scan appearance is probably not due to loosening or infection.
我们回顾了全膝关节置换术后患者进行的99m锝-亚甲基二膦酸盐（Tc-MDP）骨闪烁扫描结果。此外，还对29例患者依次进行了枸橼酸镓（Ga）闪烁扫描。确定了三组患者：无症状膝关节患者（因其他原因接受扫描）；无菌性或感染性松动患者；有疼痛但无影像学松动证据的患者。扫描结果与最终结局之间存在良好的相关性。我们得出结论，连续的99mTc-MDP和枸橼酸镓闪烁扫描有助于显示膝关节假体无菌性和感染性松动的存在，扫描表现正常的疼痛可能并非由松动或感染引起。
