Massive Eccentric Wear of the Acetabular Cup after Polyethylene Liner Abrasion in Hip Arthroplasty may lead to a high Risk of Injury during Revision Surgery.

Progressive eccentric wear of the acetabular cup after fully polyethylene liner abrasion in ceramic-on-polyethylene bearings in hip arthroplasty may be asymptomatic for a long time but may progress rapidly. To prevent patients from extensive revision surgery and the revision surgeon from serious injury due to intraoperatively findings such as razor blade sharp edges, routine long-term follow-up radiographic evaluation is crucial.
