CONTEMPORARY TOTAL HIP ARTHROPLASTY WITH AND WITHOUT CEMENT IN PATIENTS WITH OSTEONECROSIS OF THE FEMORAL HEAD

Abstract

Advancements in surgical technique and better designs have greatly improved the long-term survival of cemented and cementless implants in young patients with osteonecrosis of the femoral head. Although there was no aseptic loosening of the components, a high rate of linear wear of the polyethylene liner and a high rate of osteolysis in these high-risk young patients remain challenging problems.
