In this article, the authors report their experience with structural allografts in revision total knee arthroplasty. The complication rate was high; however, improvements in functional outcome were apparent in patients who did not experience complications.
Revision total knee arthroplasty (TKA) can often be difficult because of large bony defects. Various options are available to overcome bone stock deficiencies intraoperatively, such as the use of cancellous bone grafts, cement, small metal augments, or large megaprostheses. The use of structural allografts has been advocated by some surgeons because of their improved biocompatibility profile and ease of use in recreating bony anatomy. The disadvantages, however, lie in an increased potential for infection, resorption, and non-union.
