Revision total knee arthroplasty of bone grafts versus implant supplementation

Small contained bone defects can be managed by cement either with or without screws. Larger contained defects should be managed using morsellized allograft bone. Uncontained bone defects can be managed with implant supplements or structural grafts depending on the size and location of the defect. In the salvage situation, custom implants and arthrodesis may need to be considered.
