Fracture of femoral component in total knee arthroplasty (TKA) has become a rare complication with improvements in metal alloy manufacturing technology. We report two cases of fracture of femoral components 9 and 10 years after primary TKA. The Buechel-Pappas (BP) knee system used in our two cases w...
