BACKGROUND: The optimum treatment method for large femoral @entity79 during revision knee replacement has not been established. The purpose of the present study was to determine the initial results associated with the use of porous @entity11608 metaphyseal cones for the treatment of severe femoral @entity604 at the time of revision total knee arthroplasty. METHODS: Porous @entity11608 metaphyseal cones were implanted during twenty-four revision total knee replacements. The study group included thirteen @entity1 and eleven @entity1 with a mean age of sixty-four years at the time of the procedure. The indications for the revision procedure included @entity2096 (eleven @entity1 ), second-stage reimplantation for the treatment of @entity281 (seven @entity1 ), severe @entity3061 around a well-fixed femoral component (three @entity1 ), @entity3330 (two @entity1 ), and severe knee instability (one @entity1 ). RESULTS: The @entity1 were followed for an average of thirty-three months (range, twenty-four to fifty months). Overall, the average Knee Society clinical score improved from 55 points preoperatively to 81 points at the time of the latest follow-up. Radiographic evaluation was completed for twenty @entity1 after a mean duration of follow-up of thirty-five months. All femoral cones appeared well fixed radiographically, with no evidence of complications related to the cone. CONCLUSIONS: At the time of short-term follow-up, the porous @entity11608 metaphyseal femoral cones effectively provided structural support for the femoral implants of a revision total knee arthroplasty in this series. The potential for long-term biologic fixation may provide durability for reconstructions. Long-term follow-up and comparison with alternative reconstructive techniques will be required to evaluate the true effectiveness of this implant.
