Stochastic Simulation of Modular Connections in Total Hip Replacement

Several modern Total Hip Arthroplasty (THA) implants have been associated with increased release of metallic debris through combined mechanical fretting wear and chemical corrosion. These particles can lead to painful Adverse Reaction to Metallic Debris, often requiring early revision [1]. While much research has focused on improving the performance of bearing surfaces, the key parameters driving release of metallic debris at modular junctions remains unclear.
