Osteonecrosis was recorded when there was radiological evidence. Patients who developed AVN within the first year of SLE diagnosis were compared to those at a later stage as well as all AVN patients to 197 patients without AVN matched for disease duration. SLICC SLE damage index (SDI), and the disease activity (SLEDAI-2K) were determined at AVN diagnosis.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The prevalence of symptomatic AVN in our SLE cohort (\n                      <jats:italic>n<\/jats:italic>\n                      = 912) was 11.6% (\n                      <jats:italic>n<\/jats:italic>\n                      = 106).
