Absence of osteolysis can be expected for as many as 24 years after patients with osteonecrosis (ON) of the femoral head undergo alumina-on-alumina hip replacement.

Implant long-term durability is a challenge in total hip replacement for ON. Multiple factors may have a negative impact, including the cause of the disease, extensive and bilateral hip involvement, poor bone quality, previous surgery, young age, and high activity level.

To determine if alumina-on-alumina bearings in total hip replacement could provide effective prevention of osteolysis in young patients with ON of the femoral head, Christophe Nich, MD, and colleagues, H
