Evidence-based computer-navigated total hip arthroplasty: an updated analysis of randomized controlled trials

Data from 7 randomized controlled trials were pooled to compare the effects of computer-navigated and conventional free-hand techniques in THA. Primary outcomes included abduction angle, anteversion angle, operation time, decrease in haemoglobin after 24 hours and the number of acetabular outliers. Results indicated a significant increase in accuracy and longer operation time in the computer-navigated technique compared to the free-hand technique. There was no difference in the reduction in haemoglobin after 24 hours between the two groups.
