Abstract
This article aims to clarify the influence of design‐ and manufacturing‐related parameters on wear of metal‐on‐metal (MoM) joint bearings. A database search for publications on wear simulator studies of MoM bearings was performed. The results of published studies were normalized; groups with individual parameters were defined and analyzed statistically. Fifty‐six investigations studying a total of 200 implants were included in the analysis. Clearance, head size, carbon content, and manufacturing method were analyzed as parameters influencing MoM wear. This meta‐analysis revealed a strong influence of clearance on running‐in wear for implants of 36‐mm diameter and an increase in steady‐state wear of heat treated components. © 2009 Orthopaedic Research Society.
