Conventional Versus Computer-Assisted Technique for Total Knee Arthroplasty: A Minimum of 5-Year Follow-up of 200 Patients in a Prospective Randomized Comparative Trial
J Arthroplasty. 2014 Sep;29(9):1795-802200 patients scheduled to total knee arthroplasty were randomized to either receive a component implantation using computer assistance or through the conventional technique.
