With the increasing number of total knee arthroplasty (TKA) procedures being performed annually, the burden of revision surgery is also expected to increase. Addressing bone loss during revision TKA is a considerable challenge that requires proper preoperative evaluation and surgical planning. In addition to an assessment of femoral and tibial bone loss, a systematic approach to the management of bone loss associated with TKA includes careful implant selection, adherence to the general principles of revision TKA, and an understanding of the available reconstruction options. These options include cement with screws, morcellized allograft, bulk structural allograft, modular wedges, block augments, porous metal cones or sleeves, and megaprostheses.
