80 patients were randomized to undergo either patient-specific cutting guides (PSCGs) or conventional instrumentation total knee arthroplasty to compare the accuracy of limb alignment and component positioning between these two techniques. Post-surgical radiographs, perioperative time, blood loss and need of transfusion showed no significant differences in tibiofemoral angle or femoral component alignment. PSCG’s angle alignment was closer to neutral with shorter operating time, but these results were not clinically relevant.
