Addressing large tibial osseous defects in primary total knee arthroplasty using porous tantalum cones.

Background: Tibial osseous defects can present a serious challenge in primary total knee arthroplasty. We describe a technique of using porous tantalum cones along with primary arthroplasty implants to address large tibial osseous defects in primary total knee arthroplasty and present the short-term results.

Methods: We present 17 cases (15 patients) in which primary total knee implants and porous tantalum cones were used to address large tibial bony defects.
