Total hip arthroplasty (THA) is a definitive option for end-stage osteonecrosis of the femoral head (ONFH). Historically, higher revision rates were observed in this population compared to THA for osteoarthritis (OA). This study provides a comprehensive evaluation of postoperative medical and surgical complications comparing THA in ONFH and OA at 90 days, 1 year, and 2 years after surgery. The PearlDiver database identified 45,002 OA and 8,429 ONFH patients who underwent THA. Mechanical complications (prosthetic loosening and osteolysis, implant failure), dislocation, renal and respiratory complications were significantly increased in the ONFH group within 2 years after THA. Pulmonary embolism rates where increased in younger ONFH patients within 2 years after THA. This data helps clinicians in the postoperative risk assessment of patients with ONFH.
