Comparison of robot-assisted and conventional total knee arthroplasty: a controlled cadaver study using multiparameter quantitative three-dimensional CT assessment of alignment.

摘要: Introduction: A functional total knee replacement has to be well aligned, which implies that it should lie along the mechanical axis and in correct axial rotational planes. Incorrect alignment will lead abnormal wear, early loosening, patellofemoral problems. There been increased interest of late arthroplasty with robotic assistance. This study was conducted determine whether robot-assisted is superior conventional surgical method regard precision implant positioning.Materials Methods: Twenty replacements, comprising ten procedures operations, were performed on cadavers. Two experienced surgeons surgeries. Both each cadaver by same surgeon. The choice procedure first randomized. Following implantation prosthesis, deviation, femoral coronal angle, tibial coronal...
