The patient has a 100% radiolucent line around the femoral component as well as a distal pedestal indicating loosening of the femoral component. With these findings, there is no need to do further workup for loosening with a bone scan. Infection is unlikely with the normal laboratory findings so an indium scan is not necessary. Allograft for the femur may improve pain with a stress fracture but not in the setting of a loose femoral component. Revision of the femoral component with a cementless stem after removing the fibrous endosteal tissue and the distal pedestal is associated with the best results. Cemented revision stems in this setting are associated with early failure.
