Patients who underwent early total hip arthroplasty experienced better 10-year cup and stem survival compared with patients who underwent late total hip arthroplasty, according to study results.

Researchers searched the Medline databases from January 1990 to January 2014 and retrieved 19 articles reporting on the management of posttraumatic arthritis of the hip following acetabular fractures with the use of late total hip arthroplasty (THA), as well as articles where acetabular fractures were treated with early THA. In all, the researchers assessed THA outcomes following acetabular fracture in 654 patients.

Study results showed 75.7% of 625 fractures were treated with open reduction and internal fixation, and 24.3% were treated with nonoperative methods.

Of 604 hips for which data were available, 80.1% of patients had an uncemented acetabular component vs. 19.9% of cemented component. An uncemented femoral component was used in 59.8% of 569 hips vs. 40.2% of a cemented femoral component. Functional outcomes of 15 studies showed a median Harris Hip Score of 88 points, with 58% of patients treated with primary joint arthroplasty reporting an excellent or good Harris Hip Score vs. 76% of patients who had delayed joint arthroplasty, according to the researchers.

Kaplan-Meier survivorship analysis with any loosening, osteolysis or revision as the end point showed 10-year cup survival was 81% in patients in the early THA group and 76% in patients in the late group. Kaplan-Meier also revealed 10-year stem survival was 95% in the early THA group and 85% in the late THA group.
