Abstract
Background
Previous studies identified corrosion between the modular tibial components of total knee arthroplasty (TKA) devices. In this study, we investigated the damage modes present in titanium-titanium (Ti-Ti) junctions in the knee. We asked: under typical in vivo cyclic loading conditions, will the same alloy damage modes from TKA devices resemble those documented in the hip?
Methods
A total of 50 paired titanium alloy tibial baseplates and stems were collected and semi-quantitatively analyzed using Goldberg corrosion scoring. To characterize damage, a subsection of moderately and severely corroded components was sectioned and imaged using scanning electron and digital optical microscopy.
Results
Of the 100 device components, 95% showed visual evidence of corrosion. The initial contact area between the stem and bore generally occurred 3 mm from the stem taper base. Scanning electron microscopy revealed four damage modes, including oxide film formation, crevice corrosion, selective dissolution, and pitting.
Conclusions
Each of the damage modes identified in modular Ti-Ti tibial junctions was previously reported by total hip arthroplasty retrieval studies. Cumulatively, our results suggest that mechanically assisted crevice corrosion promoted this damage in vivo.

We used 2 SEMs in this study, including one at the Drexel Uni-versity Materials Characterization Core (RRID: SCR_022684) and another at the University of Pennsylvania Singh Center for Nano-technology (supported by the NSF National Nanotechnology Coor-dinated Infrastructure Program under grant NNCI-2025608) . We thank both Kate Vanderburgh, PhD, and Jamie Ford, PhD, for their SEM training, expert assistance, and troubleshooting efforts. We additionally thank Jeff Hancock at the University of Pennsylvania for his assistance with sectioning implants. Last, we thank Jeremy L. Gilbert, PhD, for in-depth discussions on in vivo titanium oxide film growth.
