No significant benefits with computer navigation for THA acetabular component positioning .
OrthoEvidence Journal (OE Journal) - ACE Report
OE Journal. 2014;2(8):2 J Arthroplasty. 2014 Jan;29(1):167-71. doi: 10.1016/j.arth.2013.04.017.40 patients undergoing THA were randomized for operation with either a computer-assisted navigation method or the conventional method in the positioning of the acetabular component. One surgeon performed all surgeries. Postoperative CT scans were analyzed to compare the accuracy of both methods. Analysis of the operative anteversion and inclination angles, in addition to the percentage within Lewinnek\'s safe zone, revealed similar results between both groups. Operating time was longer for the computer-assisted group, although it was not associated with an increase in complication rates.
