Figure 3.

74 year-old man with left total knee arthroplasty hardware failure and metallosis. Lateral (Fig. 3a) and AP (Fig. 3b) radiographs of the left knee were obtained after TKA revision (refer to Figs. 1a and 1b for preoperative radiographs), showing postoperative cutaneous staples. The lateral view demonstrates a small linear metallic density of the patellar polyethylene liner (arrow) in appropriate position. Notice there is now a tibial rod component in place. A joint effusion is also present.
