Cementless total hip arthroplasty after acute femoral neck fracture in active patients. Prospective matched study with a minimum follow-up of 5 years

Abstract

ObjectivesTo evaluate the outcomes of cementless total hip replacement after acute femoral neck fracture in active patients. Material and methodsA prospective matched study was conducted to compare the results of 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). ResultsThere were no significant differences in medical or surgical complications between the 2 groups. Functional outcomes were similar, but more walking aids were used in the fracture group. There were 6 revisions among the fracture 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. ConclusionCementless total hip replacement for treatment of acute femoral neck fracture showed results similar to those of elective surgery for osteoarthritis in these selected patients.
