Malpositioning of metal‐on‐metal hip resurfacing can have catastrophic outcomes. Edge loading especially, in addition to rim impingement and deformation of the acetabular component, can result in bearing failure and metallosis and pseudotumours from cobalt and chromium metal debris. This study has confirmed that the use of functional positioning in hip resurfacing results in improved precision and accuracy in achieving functional acetabular ideal zones. Overall the use of functional navigation in hip resurfacing has achieved both improved clinical outcomes and decreased complication rates leading to revision or failure.
