Even if excellent results with conventional bearings are claimed [23], usually when a THA is performed as the primary procedure for AVN, problems with polyethylene wear can arise in the medium and long term: in fact several studies have demonstrated high rates of failure with either cemented or cementless components.
These re-intervention rates are similar to what has previously been published, with earlier large cohort studies reporting rates greater than 20%, while summaries of randomized controlled trials report rates increasing from 4.2% to over 20% based upon time from the primary procedure [3, 6].
