Component fracture is a rare complication after knee replacement, especially in contemporary designs. We report the first case of a fractured femoral component in a cemented Oxford unicondylar knee prosthesis, 9 years after its implantation. Factors leading to this rare kind of component failure are discussed. Revision should be warranted in cases of unicondylar femoral component loosening, eliminating the risk of component fracture, especially in obese patients.
组件骨折是膝关节置换术后一种罕见的并发症,在当代设计中尤为如此。我们报告了首例骨水泥型牛津单髁膝关节假体植入9年后股骨组件骨折的病例。文中讨论了导致这种罕见组件故障的因素。对于单髁股骨组件松动的病例,应进行翻修,以消除组件骨折的风险,尤其是在肥胖患者中。
