Imaging After Hip Joint Replacement Surgery in the Elderly Population

Purpose of Review
The aim of this paper is to provide an overview of the hip after joint replacement and to illustrate imaging modalities and findings in the evaluation of hip arthroplasty and related complications, introducing recent diagnostic approaches.
Recent Findings
Radiography is still central and fundamental in the postoperative evaluation and follow-up. All imaging techniques play a role in the diagnosis and characterization of complications, with CT and MRI providing the most relevant recent progresses, especially focused on artifact reduction.
Summary
Hip arthroplasty is a common orthopedic procedure in elderly patients, and this is increasing in parallel to the aging of the population. Radiologists have to be familiar with surgical technique and normal postoperative findings, as well as with abnormal and pathologic conditions since several complications may occur. A correct imaging acquisition of the hip after replacement is also extremely important. This review covers imaging aspects related to the hip after joint replacement.
