Metallosis and corrosion have been associated with metal-on-metal modular total hip arthroplasty but are rarely described in the setting of primary or revision knee (TKA). In this series, we report on cases metallosis due to mechanically assisted crevice at junctions machined trunnion-bore tapers a TKA system metaphyseal sleeves. The unique design metal used sleeve-based TKA, along potential pa...

The present study deals with the pitting and repassivation behavior of a nickel-reduced austenitic stainless steel different nitrogen contents. While promoted resistance to pitting, no significant effect on was found. also aims address experimental difficulties in determining potentials owing occurrence crevice corrosion. Furthermore, mechanism ongoing reactions investigated, indicating that in...
