Early Experience With New Femoral and Tibial Cones in Revision Total Knee Arthroplasty: A Case Series

Highly porous metaphyseal cones have proven useful in revision total knee arthroplasty in providing surgeons with improved metaphyseal fixation when large contained and uncontained bony defects are encountered. In this case series, we demonstrate three patients who received the latest generation of metaphyseal cones. Specifically, these cases will highlight this new system description and its operative techniques as well as the indications for metaphyseal cone use with various real-world applications. These newer-generation porous-coated cones are excellent options for large bone defects in the absence of infection, providing adequate metaphyseal fixation without constraining final implant positioning.
