A Useful Tip for Removal of a Well-fixed Trabecular Metal Tibial Cone

We present a technique for removal of a well-fixed porous tantalum tibial cone in the setting of a revision total knee arthroplasty. The following case is of a 56-year-old man who required a repeat 2-stage revision of an infected total knee implant that included a porous tantalum tibial cone (Trabecular Metal). The patient had previously undergone a 2-stage revision and achieved excellent fixation with a stemmed, posterior stabilized, rotating platform revision implant, and a well-ingrown porous tantalum tibial cone. To potentiate a successful outcome and avoid further bone loss, this technique was implemented for tibial cone extraction. Using the Ultra-Drive Ultrasonic Revision System the well-fixed porous tantalum tibial cone was removed with minimal bone loss and without intraoperative fracture. While this was only 1 case, it provides a strategy for arthroplasty surgeons to successfully remove well-ingrown porous tantalum tibial cones in the setting of infection.
