Evaluation of implant alignment in navigated unicompartmental knee arthroplasty : a comparison of 2D and 3D imaging / Kazunari Ishida in Acta Orthopaedica Belgica, Vol.81/4 (Décembre 2015)

Public ISBD [article]  inActa Orthopaedica Belgica > Vol.81/4 (Décembre 2015) . - p.654-661 Titre : Evaluation of implant alignment in navigated unicompartmental knee arthroplasty : a comparison of 2D and 3D imaging Type de document : texte imprimé Auteurs : Kazunari Ishida ; Akihiko Toda ; Nao Shibanuma Année de publication : 2015 Article en page(s) : p.654-661 Langues : Anglais (eng) Résumé : This study aimed to compare two-dimensional (2D) and three-dimensional (3D) methods for evaluating implant alignment in navigated UKA. Nineteen UKAs in 18 subjects (7 men) were performed using an image- free navigation system. Coronal and sagittal implant alignments were assessed using radiographs (2D evaluation) and 3D image-matching software. The accuracy of 2D evaluation was compared with that of 3D evaluation. A deviation > 3° from the 3D evaluation was defined as an outlier. In the 2D evaluation, outliers for the femoral component were observed in both the coronal plane (6/19 subjects) and the sagittal plane (3/19 subjects). In UKA, assessment of the implant position might be misjudged because of the design of the implant, especially for the femoral component ; 3D methods are ideal for assessment of implant alignment.
