Does the Risk of Rerevision Vary Between Porous Tantalum

In our study, risk of rerevision for any cause or for infection did not differ between the porous tantalum group and the uncemented control group. Results have been reported in which rerevision rates after acetabular revision with the porous tantalum cup have been lower compared with the results of other uncemented revision cup designs .

Use of porous tantalum for acetabular reconstruction in

Over the past decade, porous tantalum has emerged as a powerful tool for reconstruction of the failed acetabular component. The increased porosity, high coefficient of friction, and favorable elastic modulus of porous tantalum compared with traditional titanium mesh or cobalt chromium acetabular components allow for greater bone ingrowth potential, implant stability, and host bone preservation
