Abstract
We present the peak outcome results of the Oxford medial unicompartmental arthroplasty through a minimally invasive ssurgical incision. This prospective study included 78 Oxford medial unicompartmental knee replacements in 68 patients. At the 2 year review the patients achieved a mean Oxford Knee Score of 38.3. This was not significantly different to the 2 year results of the phase 2 Oxford knee carried out using a standard parapatellar approach when patients achieved a mean OKS of 36.0. Four unicompartmental knee replacements required revision for unexplained pain, deep infection, aseptic loosening and bearing dislocation. Minimally invasive joint replacement is attractive to both patients and surgeons, but is technically demanding with complications inherent to limited access.
Résumé
Nous présentons les résultats de la prothèse Oxford unicompartimentale interne après MIS. Grâce à une étude prospective qui a inclus 78 prothèses chez 68 patients. Après 2 ans de recul, le score moyen d’Oxford est de 38.3. Il n’y a pas de résultats significativement différents entre MIS et un abord para patellaire standard (score OKS 36.0). Quatre prothèses ont nécessité une révision pour des douleurs inexpliquées, une infection profonde, un descellement aseptique ou une dislocation rotatoire. La mise en place d’une prothèse unicompartimentale par MIS apparaît satisfaisante pour les patients. Elle est néanmoins techniquement difficile pour les chirurgiens avec un risque de complications inhérent à l’accès limité de l’abord.
