Comparison of the Mechanical and Osseointegrative Performance of Porous Tantalum and Titanium for Acetabular Implantation in Total Hip Arthroplasty: A Literature Review

Introduction: Stability of the acetabular component is a critical factor in success primary and revision total hip arthroplasty (THA) procedures. As such, identification implant surface characteristics that maximize stability cup an important research objective. While titanium has historically been most commonly used material, proportion THA procedures utilizing porous tantalum (PTa) implants increased recent years. The objective this review to examine comparative mechanical osseointegrative performance PTa (PTi) interpret these results context secondary THA, as characterized by strength initial attachment successful interlocking at bone-implant interface, respectively. Methods: A literature search using predetermined protocol inclusion criteria yielded 7 articles presenting testing or osseointegration PTi THA. Results: Neither nor presented consistently superior tests designed correlate metallo-biological measures intended represent Discussion: In comparing PTi, it appears coating's pores may have more significant impact on factors affecting than metal selected. However, determining ideal pore morphology for application complex; would suggest compatibility conflict with those encourage effective osseointegration. Conclusion: When extrapolated be indicators hypothetical clinical success, are consistent recently released macro-analyses outcomes: cups, they currently manufactured, produce clinically equivalent outcomes. development comparison coating options, its complex effects must adequately accounted for; only then can we reach faithful conclusion regarding adhesion
