Overall outcome better with THA vs hemiarthroplasty in elderly with hip fracture .
Outcome of hemiarthroplasty and total hip replacement for active elderly patients with displaced femoral neck fractures: a meta-analysis of 8 randomized clinical trials
PLoS One. 2014 May 22;9(5):e98071. doi: 10.1371/journal.pone.0098071.8 randomized controlled trials (n=983) were included in this meta-analysis comparing outcomes between total hip arthroplasty and hemiarthroplasty in elderly patients. Results indicated significantly higher Harris Hip scores and a significantly lower risk of revision in the total hip arthroplasty group when compared to hemiarthroplasty. There was, however, a trend towards a higher rate of dislocation for total hip arthroplasty, although not statistically significant. The most common complication requiring revision surgery was acetabular erosion. As a whole, total hip arthroplasty appeared to be favoured over hemiarthroplasty in this population.
