Abstract
<p class="first" id="d3775902e93">Total hip arthroplasty is the most widely used procedure
to treat avascular necrosis
(AVN) of the femoral head. Few studies have compared the outcomes of THA in femoral
head AVN and primary hip osteoarthritis. Therefore we performed a case-control study
to compare THA for femoral head AVN vs. primary hip osteoarthritis in terms of: (1)
prosthesis survival, (2) complication rates, (3) functional outcomes and radiographic
outcomes, (4) and to determine whether specific risk factors for THA failure exist
in femoral head AVN.
