“…3 Currently, hard-on-soft combinations are most commonly used for hip arthroplasty. 3,9 Surgical approaches for hip arthroplasty include the anterior, anterolateral, direct lateral, lateral transtrochanteric, and posterior approach, with ongoing debate on the best approach. 14,15 The posterior and direct lateral approaches are the most common.…”

“…Loosening refers to complete loss of fixation of an implant component and is a leading cause of revision arthroplasty. 5,9 Mechanical stress over time can lead to component loosening through stimulation of synoviocyte migration into the bone-implant and bone-cement interfaces, resulting in fibrous membrane formation and the release of cytokines that stimulate osteoclasts. 5 Other causes of loosening include poor osseous integration of a noncemented component and circumferential osteolysis in the setting of component wear, as discussed later.…”

“…5,7,31 Metalon-metal hip arthroplasty systems have higher rates of ALTR than initially thought, with decreased use in recent years. 7,9 Aseptic lymphocytic vasculitis associated lesion (ALVAL) refers to the histologic appearance of ALTR with features of hypersensitivity. Microscopically, there are varying percentages of histiocytes, lymphocytes, plasma cells, and eosinophils, with variable degrees of tissue necrosis and infarction.…”

“…Mechanical loosening and dislocation are currently the most common causes of revision total hip arthroplasty in the United States. 9 Due to the wide range of potential arthroplasty-related complications and the overlapping, often nonspecific clinical symptomatology, imaging is routinely obtained to aid diagnosis and guide management. 10 Both primary hip arthroplasty and revision total hip arthroplasty rates are projected to increase dramatically in the future.…”

“…10 Both primary hip arthroplasty and revision total hip arthroplasty rates are projected to increase dramatically in the future. 7,9 Longer life expectancies, active lifestyle trends, and the growing use of arthroplasty in younger patients contribute to the escalating rates of hip arthroplasty. 7,11 As a result, there is a greater demand for imaging of hip arthroplasty across modalities.…”

Hip arthroplasty is a common and largely successful surgical procedure, often used for the treatment of advanced osteoarthritis. Imaging plays a key role in routine postoperative imaging surveillance as well as the evaluation of post-arthroplasty pain. Radiographs are the first-line imaging modality and may be followed by computed tomography (CT), ultrasound, and/or magnetic resonance imaging (MRI). Recent advancements in imaging techniques allow for metal artifact reduction on CT and MRI. A variety of complications can arise in the setting of arthroplasty: mechanical loosening, component wear-induced synovitis and osteolysis, adverse local tissue reaction, infection, periprosthetic fracture, implant dislocation and/or component displacement, tendinopathy, and neurovascular injury. This article reviews normal and abnormal imaging findings of hip arthroplasty.
