Background: Total hip arthroplasty in patients
with posttraumatic arthritis has produced results inferior to those in
patients with nontraumatic arthritis. The use of cementless acetabular
reconstruction, however, has not been extensively studied in this
clinical context. Our purpose was to compare the intermediate-term results
of total hip arthroplasty with a cementless acetabular component
in patients with posttraumatic arthritis with those of the same
procedure in patients with nontraumatic arthritis. We also compared
the results of arthroplasty in patients who had had prior operative
treatment of their acetabular fracture with those in patients who
had had prior closed treatment of their acetabular fracture.
Methods: Thirty total hip arthroplasties were performed
with use of a cementless hemispheric, fiber-metal-mesh-coated
acetabular component for the treatment of posttraumatic osteoarthritis
after acetabular fracture. The median interval between the fracture
and the arthroplasty was thirty-seven months (range, eight
to 444 months). The average age at the time of the arthroplasty
was fifty-one years (range, twenty-six to eighty-six
years), and the average duration of follow-up was sixty-three
months (range, twenty-four to 140 months). Fifteen patients had
had prior open reduction and internal fixation of their acetabular
fracture (open-reduction group), and fifteen patients had had closed
treatment of the acetabular fracture (closed-treatment group). The results
of these thirty hip reconstructions were compared with the intermediate-term
results of 204 consecutive primary total hip arthroplasties with cementless
acetabular reconstruction in patients with nontraumatic arthritis.
Results: Operative time (p < 0.001), blood
loss (p < 0.001), and perioperative transfusion requirements
(p < 0.001) were greater in the patients with posttraumatic
arthritis than they were in the patients with nontraumatic arthritis.
Of the patients with posttraumatic arthritis, those who had had
open reduction and internal fixation of their acetabular fracture had
a significantly longer index procedure (p = 0.01), greater
blood loss (p = 0.008), and a higher transfusion requirement
(p = 0.049) than those in whom the fracture had been treated
by closed methods. Eight of the fifteen patients with a previous open
reduction and internal fixation required an elevated acetabular
liner compared with one of the fifteen patients who had been treated
by closed means (p = 0.005). Two of the fifteen patients
with a previous open reduction and internal fixation required bone-grafting
of acetabular defects compared with seven of the fifteen patients
treated by closed means (p = 0.04).
The thirty patients treated for posttraumatic arthritis had an
average preoperative Harris hip score of 41 points, which increased
to 88 points at the time of follow-up; there was no significant
difference between the open-reduction and closed-treatment groups
(p = 0.39). Twenty-seven patients (90%)
had a good or excellent result. There were no dislocations or deep
infections. The Kaplan-Meier ten-year survival
rate, with revision or radiographic loosening as the end point,
was 97%. These results were similar to those of the patients
who underwent primary total hip arthroplasty for nontraumatic arthritis.
Conclusions: The intermediate-term clinical
results of total hip arthroplasty with cementless acetabular reconstruction
for posttraumatic osteoarthritis after acetabular fracture were
similar to those after the same procedure for nontraumatic arthritis,
regardless of whether the acetabular fracture had been internally fixed
initially. However, total hip arthroplasty after acetabular fracture
was a longer procedure with greater blood loss, especially in patients
with previous open reduction and internal fixation. Previous open
reduction and internal fixation predisposed the hip to more intraoperative
instability but less bone deficiency.
