“…However, that is rarely the case. The release of corrosion products may elicit an adverse biological reaction in the host, and several authors have reported increased concentrations of local and systemic trace metals in association with metal implants [3,4]. Titanium alloys possess attractive properties for biomedical applications, the most important being biocompatibility.…”

The purpose of this study was to characterize the prevalence of taper damage in modular TKA components. 198 modular components were revised after 3.9±4.2y (range: 0.0–17.5y). Modular components were evaluated for fretting corrosion using a semi-quantitative 4-point scoring system. Flexural rigidity, stem diameter, alloy coupling, patient weight, age and implantation time were assessed as predictors of fretting corrosion damage. Mild-to-severe fretting corrosion (score≥2) was observed in 94/101 of the tapers on the modular femoral components and 90/97 of the modular tibial components. Mixed alloy pairs (p=0.03), taper design (p<0.001), and component type (p=0.02) were associated with taper corrosion. The results from this study supported the hypothesis that there is taper corrosion in TKA. However the clinical implications of fretting and corrosion in TKA remain unclear.

“…32 However, significantly high metal concentrations in body fluids of patients with Co-Cr alloy metalon-metal bearing hip implants have been reported. [33][34][35] Similar to Co-Cr alloy, when Co-Cr-Mo alloy was used, 50 times that of the normal values of Co and Cr in the lung, kidney, liver, and spleen have been detected after 6 months of successful implantation. 4,36 The wear debris, generated primarily at the interface between the femoral head and the acetabular cup, was identified as the main factor limiting the life of the implant.…”
