“…However, Bauwens et al [18] reported that the alignment of the mechanical axes was similar in the navigation and conventional surgery groups in a metaanalysis of 33 studies. The reason for the contradictory results might rest in the implanting and/or radiographic error, which Bauwens et al [18] did not assess. Ninety-eight per cent of patients had a frontal tibiofemoral angle that was within 3°of the ideal with radiographic measurement in our study.…”

Purpose The purpose of this study was to evaluate the accuracy of bone cutting and implantation in minimally invasive total knee arthroplasty with image-free navigation. Methods The alignment of the tibial and femoral bone resection was measured in 40 knees during surgery. The alignment measurement was repeated after cementing the tibial and femoral components. We evaluated the cutting error and the implanting error. Results The mean tibial cutting errors were 0.5 and 0.7°in the frontal and sagittal planes, respectively. The mean femoral cutting errors were 0.5 and 0.9°in the frontal and sagittal planes, respectively. The mean tibial implanting errors were 1.0 and 0.9°in the frontal and sagittal planes, respectively. The mean femoral implanting error was 0.7°in the frontal plane. Conclusions Computer-assisted navigation was useful in checking the alignment of both bone cut and cementation.

“…There are now numerous published precision studies in the literature which report on the clinical outcomes of procedures performed using a navigation system [2,15,18,20], including a recent study evaluating initial experience with EM technology [1]. The majority of cadaver and clinical studies have validated the precision of these systems in specimens or patients with normal or near normal preoperative lower limb mechanical alignment, in terms of postoperative component alignment [6,16].…”

“…There are now many published studies on various authors' experience with navigated TKA, most of which demonstrate a reduction in risk of implant malposition and more precise leg alignment when compared to conventional jig-based alignment guides [2,4,5,7,10,17,19]. However, an important distinction needs to be drawn between precision and accuracy evaluation.…”

The objective of this study was to develop a method to assess the accuracy of an electromagnetic technology image-free navigation system for total knee arthroplasty in a leg with normal or abnormal mechanical alignment. An acrylic phantom leg was constructed to simulate tibia and femur deformation. Determination of actual leg alignment was achieved using a digital caliper unit. In the setting of normal alignment, the mean error of the system characterised as the difference between the measured computer navigation and digital caliper angles ranged between 0.8°(frontal plane) and 1.5°(lateral plane). In the setting of abnormal alignment, the mean error ranged between 0.4°(frontal plane) and 1.6°(lateral plane). Deformity had no demonstrable effect on accuracy. The study demonstrates satisfactory in vitro system accuracy in both normal and abnormal leg mechanical alignment settings.Résumé Le but de cette étude était d'évaluer les techniques de navigation sans image par technologie électro-magnét-ique au cours des prothèses totales du genou. Un fantôme acrylique de membre inférieur a été construit de façon à simuler la déformation du tibia et du fémur. La différence moyenne entre la mesure par computer et la mesure instrumentale est de 0,8°dans le plan frontal et de 1,5°d ans le plan latéral. Dans les cas de mauvais alignements la moyenne a été de 0,4°dans le plan frontal et de 1,6°sur le profil. Cette étude in-vitro montre que ce système est fiable aussi bien pour un membre inférieur normalement axé que désaxé.

“…Computer-assisted surgery (CAS) has become established in a number of areas of orthopaedic surgery, particularly in knee arthroplasty [1]. In sports surgery of the knee, the two main procedures for which clinical results have been published are anterior cruciate ligament (ACL) reconstruction and high tibial osteotomy (HTO).…”

Computer-assisted surgery (CAS) has been investigated in a number of sports medicine procedures in the knee. Current barriers to its widespread introduction include increased costs, duration, and invasiveness of surgery. Randomized trials on the use of CAS in anterior cruciate ligament reconstruction have failed to demonstrate a clinical benefit. Data on CAS use in high tibial osteotomy are more promising; however, long-term studies are lacking. CAS has a number of research applications in knee ligament surgery, and studies continue to explore its use in the treatment of osteochondral lesions. This article reviews the applications of CAS in sports medicine knee surgery and summarizes current literature on clinical outcomes.
