Performing a Safe and Effective Total Hip Arthroplasty on Patients With Inactive or Stably Active Systemic Lupus Erythematosus With Osteonecrosis.

Performing THA for patients with SLE in an inactive or stably active disease condition resulted in comparable postoperative HHS and MCS scores, a lower PCS score, and shorter term postoperative complications compared with patients with ONFH resulting from nonrheumatic diseases. Patients with SLE had a higher risk for postoperative complications. It is generally safe and effective to perform THA in patients with inactive or stably active SLE. However, they still have an increased risk of short-term complications.
