Abstract：
METHODS: Failure of the modular junction in revision total knee arthroplasty is a rare complication. We report a patient with late, atraumatic failure of a modern, modular revision femoral component, with preoperative elevation of serum cobalt and chromium levels. Retrieval analysis showed extensive chemical corrosion.
CONCLUSIONS: Failure of a modern, modular femoral component may cause metal synovitis and elevated serum metal levels. Subtle radiographic changes and preoperative serum metal levels may identify this complication.

摘要：
方法：全膝关节置换术中模块化连接失败是一种罕见的并发症。我们报告一个病人迟到了，现代的无创伤失败，模块化翻修股骨组件,术前血清钴和铬水平升高。反演分析显示广泛的化学腐蚀。
结论：现代的失败，模块化股骨组件可能会导致金属滑膜炎和血清金属水平升高。细微的影像学变化和术前血清金属水平可能会识别出这种并发症。
