Revision strategies in total hip arthroplasty with respect to articulation materials
Revision of a total hip arthroplasty needs comprehensive knowledge of the characteristics of the articulating materials. A wrong re-implanted wear couple can lead to early re-failure.
Selection of articulation in primary THA can be influenced by possible revision scenarios. Today the new XL-PE, metal-on-metal and ceramic-on-ceramic articulations offer excellent wear behaviors. Concerning the amount of wear, ceramic-on-ceramic seems to be the favourite. Nevertheless, a certain amount of risk for fractures has to be considered.
