A 52-year-old woman with a medical history of breast cancer metastatic to multiple sites on lapatinib, hypertension, and history of left TKA 9 years prior sustained a Type 3A open periprosthetic left distal femur fracture in a motor vehicle collision (Figure 1). She was continued on IV cefazolin 2 g every 8 h until definitive revision surgery, and in delayed fashion, she was treated with conversion of her TKA to distal femoral replacement (Figure 1).
