The study compared 520 patients with osteoarthritis who underwent computer-assisted surgery for one knee and traditional knee arthroplasty for the other. After clinical assessments, no statistically significant differences were found between the two methods.
The survivorship of the implants was 10.8 years after operation and the length of operative time was significantly longer among the computer-navigated knees. No difference was shown in the incision length, intraoperative blood lose, volume of drainage, duration of drainage or transfusion volume.
