Assessment of Corrosion, Fretting, and Material Loss of Retrieved Modular Total Knee Arthroplasties

摘要

Background: Modular junctions in total hip arthroplasties have been associated with fretting, corrosion, and debris release. The purpose of this study is to analyze damage severity in total knee arthroplasties of a single design by qualitative visual assessment and quantitative material loss measurements to evaluate implant performance and patient impact via material loss.
