Novel Utilization of Revision Cones for Femoral Condyle Lysis in Revision Total Knee Arthroplasty.

Novel Utilization of Revision Cones for Femoral Condyle Lysis in Revision Total Knee Arthroplasty.

Significant bone loss is a major challenge in revision total knee arthroplasties (TKAs), especially with large femoral condylar defects. Restoring the metaphyseal-diaphyseal junction and central bone loss is critical for stability and reducing risk of component loosening. We describe a novel technique that uses a helical burr to modify porous metal cones intraoperatively, creating a custom fit without impinging on the femoral component. This approach promoted reliable osseointegration and stability in two patients with femoral condyle osteolysis. Additionally, we present a review of data demonstrating the success of metal cones in achieving osseointegration and decreased instability. Early findings suggest that intraoperative cone sizing and custom modification is a reliable technique for optimizing outcomes in the setting of femoral bone loss in revision TKA.
