Hip arthroplasty is a common and effective operation with a high success rate. The purpose of this essay is to review the various imaging modalities can be used in the assessment of complicated hip arthroplasty. Postoperatively, serial plain radiographs remain the modality of choice to evaluate patients following arthroplasty. The technical assessment of the postoperative radiograph is considered, together with important landmarks and subsequent long-term changes. With proper imaging modification techniques, CT and MRI with their superior resolution and increased sensitivity can evaluate the joint and surrounding osseous and soft tissue structures. CT can assess subtle fractures and extent of osteolysis better than radiographs. MRI has an advantage over the other imaging modalities in its ability to demonstrate both soft tissue and intraosseous abnormalities. This article will review the current and future role of radionuclide imaging in establishing the presence, and determining the cause of prosthetic joint complications
