Managing very distal femoral periprosthetic fracture above a total knee arthroplasty (TKA) is a difficult problem. When a cruciate sacrificing TKA is used, bone stock around the implant is compromised and, therefore, can limit fixation options. We present technique using the revision system femoral stem for the PFC Sigma TKA (Depuy; Leeds, England) to stabilize this particular type of fracture.
处理全膝关节置换术（TKA）以上的非常远端股骨假体周围骨折是一个难题。当使用牺牲交叉韧带的 TKA 时，假体周围的骨量受到影响，因此，会限制固定选择。我们介绍了一种使用 PFC Sigma TKA（Depuy；英国利兹）的翻修系统股骨柄来稳定这种特殊类型骨折的技术。
