Abstract:
The best strategy to address large bony defects in revision total knee arthroplasty has yet to be determined. The relatively recent development of porous tantalum cones and their use to address massive bone loss in knee arthroplasty has shown promising short- and intermediate-term results. The purpose of this review is to present the current literature on: (1) basic science of porous tantalum, (2) classification and treatment for bone loss, (3) clinical results, and (4) evolution of newer generation cones.
Insights
Porous tantalum cones show promise for addressing large bone defects in revision knee replacement surgery. This review covers their science, use, and clinical outcomes for massive bone loss.
