広範囲な骨欠損に対し腫瘍用人工膝関節を用いた再置換術の治療経験 The Use of A Tumor Prosthesis in Revision Total Knee Arthroplasty with Severe Bone Defects ; A Case Report
This report describes a case of revision total knee arthroplasty (TKA) using a tumor prosthesis. The patient was a 79 year-old woman who had undergone left TKA at the age of 65. After her primary TKA, she continued working on a farm, but 13 years after that surgery, she became unable to walk due to severe left knee pain and instability. The x-ray images of her left knee showed a breakage of the tibial metal tray and severe bone defects of her distal femur and proximal tibia. Revision TKA was performed using a Kyocera Physio Hinge total knee system. At present, 3 years after operation, she is able to walk with a cane, and there is no loosening on x-ray images.
