Background:
Total hip arthroplasty (THA) is a common surgical treatment when significant joint changes and pain are present after acetabular fracture. Few series have been reported in the literature with cemented and uncemented acetabular components. The aim of this study was to analyze the long-term results of cementless acetabular components inserted in acetabula that had been altered with previous fracture and to compare these results to those of routine THA.
Methods:
Twenty-four uncemented total hip arthroplasties were performed for the treatment of posttraumatic arthritis after acetabular fracture. The mean age and follow-up was 56 years and 8.4 years, respectively. The results were compared with 48 primary uncemented total hip arthroplasties in patients with nontraumatic arthritis. Clinical assessment with Harris hip score and radiologic with special interest in the socket was made.
Results:
No significant difference between the two cohorts was found with regard to postoperative follow-up, perioperative transfusion requirements, reoperations, and acetabular survival. Between both cohorts, there were significant differences with regard to operative time and postoperative Harris score.
Conclusions:
Cementless THA is a suitable treatment for posttraumatic arthritis after acetabular fracture.
Level Of Evidence:
Therapeutic study, level III.
