(A) This proximal tibial plateau fracture was treated with open reduction and internal fixation. Elevation of the depressed plateau created a bone void in the lateral condyle which was filled with a composite of α-tricalcium phosphate, calcium carbonate and monocalcium phosphate (Norian™) (white arrow). (B) Radiograph taken 4 years later shows no remodelling of this very stable ceramic. (C) The patient presented again at 6.5 years after implantation of the ceramic with an abscess over the lateral tibia (white arrows) and septic arthritis of the knee. The ceramic material remains unchanged and is now involved in the infection. It was difficult to remove at surgery.
