Abstract

Ninety-seven patients with 99 total knee arthroplasties were operated on by a surgeon in the first 3 years of his surgical career. Complete survival data were available for all 99 knees. The cases were reviewed at a minimum of 10 years after their initial operation, but as 37 patients had died before reaching 10 years, the average follow-up was 8 years 8 months with a maximum of 12 years 4 months. Ninety-one patients had osteoarthritis, five had rheumatoid arthritis, and three had juvenile chronic arthritis. No patients were lost to follow-up. Four required revision. The 10-year survival rate, using revision for all causes as an end-point, was 94.96%. The survival rate for aseptic loosening was 97.04%. The survival rate for loose joints that had not been revised was 94.13%. Three of the four revisions occurred in the first 6 patients operated upon, suggesting there may be a learning curve for surgeons at this stage in their career.

Résumé

Quatre-vingt-dix-sept patients ayant bénéficié de 99 prothèses totales du genou mises en place par un seul chirurgien lors de ces trois premières années d’activité. Toutes les données ont été récoltées pour ces 99 genoux. Ces patients ont été revus avec un minimum de 10 ans après l’intervention. Trente-sept étaient décédés. Le suivi moyen était de 8 ans 8 mois avec un maximum de 12 ans 4 mois. Quarante-vingt-onze patients avaient été traités pour arthrose, 5 pour arthrite rhumatoïde et 3 pour arthrite rhumatoïde juvénile, maladie de Still-Chauffard. Aucun patient n’a été perdu de vue. Quatre ont nécessité une reprise chirurgicale. Le taux de révision à 10 ans en prenant comme contrôle la révision quelle que soit la cause a été de 94.96%, le taux de survie pour descellement aseptique de 97.04%. Le taux de survie pour les patients qui n’ont pas été repris a été de 94.13%. Trois des quatre révisions sont survenues chez les six premiers patients opérés par le chirurgien et faisaient partie de la courbe d’apprentissage.
