Postoperative imaging of the hip used to be dominated by radiographs, computed tomography, and occasionally nuclear medicine studies, given that most surgeries were arthroplasties or, less commonly, core decompressions. The indications and procedures performed have expanded well beyond arthroplasties and now include labral procedures (resections, repairs, and reconstructions), osteochondroplasties, acetabuloplasties, and removal of loose bodies, among others. As a result, postoperative evaluation of the hip now often includes MR imaging and MR arthrography. This article discusses normal postoperative appearances and some of the more common complications associated with hip arthroscopy and hip arthroplasty with a focus on MR imaging.
