title: Contrary view: wear is not an issue.
abstract: Wear was not an issue with total knee replacements that had a round-on-round design such as the Total Condylar and the Insall-Burstein prostheses. As long as designs do not try to reproduce normality in kinematics, wear will not be an issue. To date, there are no data that mobile-bearing knee replacements will decrease wear complications as compared with round-on-round fixed designs. Wear is not an issue if the total knee replacement is done with a round-on-round design with a cobalt chrome femoral component, monoblock tibial component, and an all-polyethylene patella, all with cemented fixation.
