This study aimed to: (1) compare published follow-up guidelines for metal-on-metal (MoM) hip patients and analyse protocols in relation to current evidence, and (2) assess the financial implications of these guidelines. Follow-up guidance for MoM hips from five national authorities (MHRA in the UK; EFORT; United States FDA; Therapeutic Goods Administration of Australia; Health Canada) were contrasted and critically appraised. Using National Joint Registry (NJR) data (67,363 MoM hips implanted) the cost of annual surveillance for all MoM hips recorded in the NJR was calculated for each protocol.Introduction
