Abstract
in English, French

One hundred and eleven total knee replacements without patellar resurfacing were followed-up for a minimum of 48.8 months (range 48.8-108.2 months; average 78.2 months). Evaluation was performed using the Knee Society Clinical Rating System (KS-CRS). Preoperatively, the mean knee score was 34.3 points and the mean function score was 42.2 points. Postoperatively, this knee score improved to a mean of 91.1 points and the function score improved to mean of 89.6 points at the most recent follow-up. There were no significant differences among the knees with mild, moderate, or severe degenerative change to the patella with regard to the preoperative (p=0.83) and postoperative (p=0.39) knee pain score. It seems likely that the postoperative knee pain is not related to the severity of degenerative change to the patella in total knee arthroplasties performed without patellar resurfacing, and none of those patients required patellar resurfacing to achieve knee pain relief.

Une série de 111 prothèse totales de genou sans resurfaçage patellaire a été suivi un minimum de 48 mois (de 48,8 à 108,2 mois avec une moyenne de 78,2 mois). L’évaluation a été faite selon le score clinique de la Knee Society (KS-CRS). Le score du genou est passé de 34,3 à 91,1 points et le score fonctionnel de 42,2 à 89,6 points entre l’état pré-opératoire et le plus récent recul. Il n’y avait pas de différence significative selon l’état dégénératif de la rotule. Il semble que les douleurs post-opératoires ne sont pas en relation avec l’atteinte de la rotule. Aucun des patients n’a eu besoin d’un resurfaçage rotulien en raison de douleurs du genou.
