Study Summary
The purpose of this study is to determine the amount of polyethylene wear associated with knee replacement designs that incorporate either a fixed or mobile bearing. Tibial polyethylene inserts retrieved from modular total knee replacements during revision operations will be analyzed by obtaining micro-CT images of the retrieved inserts. The components of total volumetric polyethylene loss, including wear associated with the medial articular, lateral articular and backside regions of the insert be quantified by comparing the worn insert with an unworn control. The investigators hypothesize that the fixed bearing inserts where the polyethylene is locked to the metal baseplate will demonstrate more volumetric wear than the mobile bearing inserts that are designed to slide or rotate on the metal baseplate.
Primary Outcome
Total volumetric polyethylene wear will be measured among mobile and fixed bearing tibial inserts retrieved during a revision surgery.
