Background: The treatment of end-stage osteonecrosis of the femoral
head remains a challenge to the orthopaedic surgeon. Historically, total hip
arthroplasty for this condition has been associated with poor rates of
survival and function when compared with total hip arthroplasty for the
treatment of osteoarthritis. The purpose of this study was to determine the
medium-term clinical and radiographic results of metal-on-metal hip
resurfacing arthroplasty in patients with end-stage osteonecrosis of the
femoral head.
Methods: From June 1994 to March 2004, a consecutive single-surgeon
series of seventy-three hip resurfacing procedures were performed in sixty
patients for the treatment of end-stage osteonecrosis of the femoral head. The
cohort included forty-two men (ten of whom had a bilateral resurfacing) and
eighteen women (three of whom had a bilateral resurfacing). The mean age was
forty-three years (range, seventeen to sixty-nine years). A clinical and
radiographic review was performed.
Results: There were four revision operations and one planned
revision of the seventy-three hips during the follow-up period. Two of these
revisions were necessitated by aseptic failure of the femoral component. This
represents an overall survival rate of 93.2% at a mean of 6.1 years of
follow-up (range, two to twelve years).
Conclusions: On the basis of this study, metal-on-metal resurfacing
of the hip for osteonecrosis can be considered a safe and effective form of
surgery for this group of patients. Longer-term follow-up is required to
confirm the expected continued success of this form of arthroplasty in this
difficult-to-treat population.
