To evaluate outcomes of cementless total hip replacement after acute femoral neck fracture in active patients.
A prospective matched study was conducted to compare the results between 76 patients with fractures and 76 patients with osteoarthritis. The Harris score, short-WOMAC and SF-12 were used for the clinical assessment. The mean follow-up was 7.3 years (range 5-11).
There were no significant differences in medical or surgical complications between the 2 groups. Functional outcomes were similar, but more walking aids were used in fracture group. There were 6 revisions among the fractures group (one dislocation, 2 deep infections, 3 aseptic loosening), and 2 aseptic loosening among controls. There was no significant difference in arthroplasty survival at 10 years (88.7 vs. 96.1%, P=.15). The mortality rates at 2 and 10 years were similar.
Cementless total hip replacement for treatment of acute femoral neck fracture showed similar results to those of elective surgery for osteoarthritis in these selected patients.
