Complications following total hip replacement can be broadly divided into systemic and procedure specific complications. Overall, incidence of complications have improved over time as surgical and anaesthetic techniques have improved along with the diagnosis and management of such complications.

The most common systemic complication is a deep vein thrombosis. Infection is the most feared complication but the incidence have reduced with prophylactic antibiotics and improved theatre environment.
