Dissociation of the polyethylene from the metal baseplate of the patellar component in total knee arthroplasty (TKA) occurred in two patients. Analysis of intraoperative and postoperative photographs of the specimens indicates that "cold flow" of the polyethylene precedes dissociation from the metal baseplate. The diagnosis can be made on the basis of a pathogonomic metallic crepitus.
在全膝关节置换术（TKA）中，两名患者的髌骨组件聚乙烯与金属基板发生分离。对标本的术中和术后照片分析表明，聚乙烯的“冷流”先于其与金属基板的分离。可根据典型的金属摩擦音做出诊断。
