Analysis Techniques for Polyethylene Implants in Total Knee Arthroplasty

Source

Analysis of retrieved implants is a multistep process that can be approached in a variety of ways. To researchers, this analysis is vital to assessing how the implant functioned after surgery. Traditionally, this involves examination of components by one or several experts who then give feedback on the severity of observable damage. Engineering approaches attempt to minimize subjectivity by introducing standardized techniques that can quantify damage, such as microcomputed tomography analysis of retrieved polyethylene components. Methods such as these provide an objective way to measure damage and can be used in addition to subjective techniques such as visual inspection. This chapter will entail a review of the available processes that can be utilized to properly analyze how and why a polymer insert in a total knee arthroplasty implant failed.
