Abstract

Highly porous metaphyseal cones are used for the management of large bone defects in revision total knee arthroplasty. These cones fill defects and allow bony ongrowth while providing several sizing and offset options. In this case series, we evaluated three patients who received these latest generation metaphyseal cones. Specifically, these cases will be explored in detail with respect to history, indications, operative technique, and short-term outcomes. Overall, these newer generation porous coated cones are excellent options for large contained bone loss in the absence of infection, and they have demonstrated good clinical and radiological outcomes at short-term follow-up.
