Revision of well-fixed cemented, porous total knee arthroplasty. Report of six cases.
Revision of cemented, porous ingrowth total knee arthroplasties poses several technical problems that are unique to these implants, especially component extraction. Six cases are presented to illustrate these difficulties, with particular attention given to revision techniques. The revisions were performed not for aseptic loosening but for causes in which all the implants were securely affixed to bone. To avoid large amounts of bone loss during extraction, the cement-prosthesis interface should be disrupted with high-speed instruments, such as a high-speed burr or oscillating saw. The tibial component may need to be disassembled to gain access to the tibial fixation peg. The potential problems of revision of cemented, porous total knee implants may necessitate bone grafting or custom-designed prostheses.
