Project objectives
The knee is formed by a complex biomechanical system which requires an accurate knowledge of both the functional anatomy and the kinematics of the joint itself. In order to identify the correct parameters for the implantation of a prosthetic apparatus, the use of radiological (preoperative) and anatomical (intraoperative) measurements is essential. Although the measurement methods used are now well established in traditional practice, according to the literature, the risk of incorrect alignment of the prosthesis continues to occur with a percentage of patients reporting poor satisfaction following surgery. Currently, the studies that highlight the peculiarities of navigation in prosthetic surgery are few, do not lead to definite conclusions and have a follow-up that is often too short due to the recent introduction of this system. Some recent studies have shown that some advantages (less deviation of the mechanical axis on the various planes) are observable and significant in the very short term (1 year). However, the functional results did not show any significant difference between patients operated with navigation and those operated with traditional technique, neither in the short term (1-2 years) nor in the long term (5-7 years). Analyzing the peri-operative parameters, it was observed that intra-operative blood loss was significantly lower in patients operated with the navigation-assisted technique, compared to those operated with the traditional technique.
The main objective of the study is to identify the strengths and limitations of the total knee replacement procedure with computer-assisted navigation. This objective will be pursued by comparing the navigated procedure with the traditional procedure.
