Anteroposterior radiographs of a 48-year-old woman who underwent revision THA for periprosthetic joint infection. a Radiograph prior to stage 2 revision THA showing the antibiotic-loaded spacer in situ. b Radiograph immediately after revision THA using a cementless extensively porous-coated stem without cortical strut allografts. c Postoperative radiograph at 1 year showing loss of cortical density and thickness in the proximal femur, suggesting moderate area and severity of stress shielding. d Postoperative radiograph at 5 years showing severe stress shielding and distal cortical hypertrophy on both the medial and lateral sides. e Postoperative radiograph at 10 years showing more severe bone loss and distal cortical hypertrophy
