MRI following UKA : The component-bone interface / Dominik Malcherczyk in Acta Orthopaedica Belgica, Vol. 81/1 (Mars 2015)

Public ISBD [article]  inActa Orthopaedica Belgica > Vol. 81/1 (Mars 2015) . - p. 84-89 Titre : MRI following UKA : The component-bone interface Type de document : texte imprimé Auteurs : Dominik Malcherczyk, Auteur ; Jens Figiel, Auteur ; Ulrike Hähnlein, Auteur Année de publication : 2015 Article en page(s) : p. 84-89 Langues : Anglais (eng) Mots-clés : UKA  MRI  Knee  Unicompartmental Knee Arthroplasty  Magnet Resonance Imaging  Component-bone interface Résumé : Introduction : Loosening is one of the major longterm failure modes in unicondylar knee arthroplasty (UKA). The aim of the study is to describe and characterize implant-bone interface of femoral and tibial components after UKA by means of magnet resonance imaging (MRI). Material and Methods : MRI tailored to reduce metallic artefact of the knee after medial UKA was performed in 10 patients as a pilot study. The component-bone interface at femoral and tibial components was evaluated by two independent investigators. They gave degree of confidence to their evaluation of each parameter on a five-point scale. Inter-observer reliability was determined. Results : Artefacts provoked by the implants were rare. Inter-observer reliability and confidence were excellent for the femoral interface. They were lower at the tibial interface but results were still satisfactory. Conclusion : Tailored MRI allows reproducible analysis of the component-bone interface after UKA. It is helpful in assessment of suspected loosening after UKA.
