In total knee arthroplasty (TKA), a treatment of bone defect varies depending on the\nlocation and extent of defect and requires proper surgical procedure. Metal augmentation\nis readily available for both femoral and tibial bone defects. We report the\noperative technique of modular metal augmentation using a downsized block for\nambiguous proximal tibial and distal femoral bone defects in primary and revision\nTKA. Regarding bone defects, bone loss can be minimized by using a different size of\nmetal augmentation, and suitable reinforcement for bone defects can be achieved.\nOnce our technique is properly used, it will be very helpful in treating bone defects.
