Background: The influence of pre-existing radiographic osteoarthritis on the functional outcome of elderly patientents with displaced intracapsular fractures of the femoral neck treated by hemiarthroplasty is unclear. Methods: We prospectively examined the impact of pre-existing osteoarthritis on the functional outcome of 126 elderly patients with displaced intracapsular fracture of the femoral neck treated by hemiarthroplasty. Results: The mean age of the cohort was 82.7 years. At 12 months, we observed no statistically significant differences in the Harris hip score (p∈=∈0.545), the timed up and go test (p∈=∈0.298), the Tinetti test (p∈=∈0.381) or the Barthel Index (p∈=∈0.094) between patients with Kellgren and Lawrence grades 3 or 4 osteoarthritis, and patients with grades 0 to 2 changes. Furthermore, there were no differences in complication or revision rates. Conclusions: Our findings challenge the hypothesis that pre-existing osteoarthritis is a contraindication to hemiarthroplasty in elderly patients with femoral neck fracture.
