Osteolysis In a Well Fixed Acetabular Cup, Retain or Revise?

Abstract

Wear and Osteolysis are the commonest cause of aseptic loosening in Total Hip Arthroplasty (THA), requiring revision. A less invasive approach could be undertaken in terms of an earlier intervention by isolated the liner change only. Indications and contraindications of each approach are reviewed with some technical tips. Outcome results have shown that isolated liner exchange alone does have a higher risk of instability.
