Introduction The outcomes of total hip arthroplasty (THA)
for the treatment of posttraumatic arthritis after acetabular
fractures were inferior to those after primary non-traumatic
THA.
Methods This study was performed in academic level I
trauma center. From January 2011 to December 2014, a consecutive
series of 21 patients (9 females), with average age
of 56.7 years (range 29–75 years) who had posttraumatic hip
joint arthritis after acetabular fractures, were included in our
study. All patients underwent cementless THA. The average
duration of follow-up was 26 months (range 24–36 months).
Results At the latest follow-up, all patients could walk
independently, thirteen (62%) patients had excellent Harris
hip score, five (24%) had good HHS, and 3 (14%) had fair
score. WOMAC scale decreased from 63 (range 42–92) to
4 (range 0–19). Two patients (9.5%) had heterotopic bone
formation which did not affect the activity of the patients.
There were no signs of loosening of the acetabular cups or
around the femoral stem.
Conclusion Cementless THA is an ideal treatment for posttraumatic
hip arthritis with anatomic restoration of the hip
center to improve the functional results and decrease the
incidence of complications and revision rate.
