摘要

class="Heading">Background class="Para">In megaprosthetic knee replacement, surgeons use cutting guides that depend on anatomLevel of evidence class="Para">ical references to determine the ideal cutting plane alignment. In this work, we investigated the accuracy of using femoral cortical surfaces and tibial canal portions as the references. The study aims to improve the design and use of the cutting guides. class="Heading">Materials and methods class="Para">Sixty-one knee scanograms of 33 patients (mean age around 20?years) diagnosed with osteogenic sarcoma and undergoing distal femur megaprosthetic surgery were acquired. Angles between the selected anatomical references and axis perpendicular to the ideal cutting plane (anatomical axis for femur and mechanical axis for tibia) were measured for both femur and tibia, in coronal view. The smaller the magnitude of the angles, the better the anatomical reference is. class="Heading">Results class="Para">At the central femoral region, on average, both lateral and medial cortical surfaces give accurate alignment of the ideal cutting plane (0.6° and 0.8°, respectively), with no significant difference (p??0.01). At the distal region, the lateral cortical surface gives significantly better alignment compared to the medial cortical surface (p??0.01), but not as accurate (1.4°) as in the central region. For tibia, the central tibial canal gives significantly accurate alignment of the ideal cutting plane (?0.3°) on average, compared to the proximal tibial canal (p??0.01). class="Heading">Conclusions class="Para">For a femoral cut, both lateral and medial cortical surfaces are the best anatomical references, but only at the central region. For a tibial cut, the central anatomical axis is the best reference. class="Heading">Level of evidence class="Para">IV.
