Abstract
Recently, patellofemoral arthroplasty has attracted increased interest as a salvage treatment for isolated patellofemoral arthritis. However, there are very few reports of the experience with modern generation patellofemoral arthroplasties. This investigation describes a collective experience of four centres reporting on the outcome in patients of the use of one patellofemoral arthroplasty device. There were 70 patients (79 knees) who had failed an extensive non-operative treatment regimen and/or various conventional alternative surgical treatments. At a mean follow-up of three years (range: 2–6 years), there were 66 knees that had Knee Society Scores greater than 80 points (84%). Seventy-one knees (90%) functioned without pain in daily activity and stair climbing. Symptomatic isolated patellofemoral arthritis was successfully treated with a patellofemoral arthroplasty in the short term. We are encouraged by these excellent early results and await longer follow-up.
Résumé
Les prothèses fémoro patellaires ont connu récemment un intérêt croissant dans le traitement des arthroses fémoro patellaires isolées. Cependant, peu de nouveaux travaux sont publiés concernant la nouvelle génération des prothèses fémoro patellaires. Cette étude a pour but de décrire l’expérience collective de 4 centres rapportant le devenir de patients ayant bénéficié d’une prothèse fémoro patellaire. 70 patients (69 genoux) traités après échec d’un traitement médical alternatif. Après un suivi moyen de 3 ans (2 à 6 ans), 66 genoux ont un score IKS supérieur à 80 points (84%). 71, 90% ne présentent pas de douleur dans les activités habituelles de la vie telle la montée des escaliers. La symptomatologie de l’arthrose fémoro patellaire peut être traitée avec succès par une prothèse fémoro patellaire dans le court terme. Encouragés par ces excellents résultats précoces il est nécessaire d’avoir une nouvelle évaluation avec un plus long suivi.
