Background:There is controversy about whether to retain or excise the posterior cruciate ligament in rheumatoid knees because attenuation of the ligament is often present in this subgroup of patients. We reviewed more than 15 years of results of cruciate-retaining total knee replacements (TKRs) in patients with rheumatoid arthritis. Methods:We reviewed patients' charts and radiographs to evaluate knee range of motion and flexion contractures, component loosening and osteolysis at the bonecement interface. Our primary outcome was revision of a femoral or tibial component for any reason, and the secondary outcome was revision for any reason and periprosthetic fracture during the follow-up period.Results: Our study included 112 patients (7 men, 105 women, 176 knees). Their mean age was 49.3 (range 33-64) years. Twenty-one patients died and 16 were lost to followup, leaving 75 patients (119 knees) with a minimum follow-up of 15 (mean 16.1) years for our analysis. Of these, 61 patients (101 knees) were available for clinical and radiological evaluation at the final follow-up assessment. At a mean of 12.2 (range 6-16) years, revision was necessary in 14 patients (19 knees), including 1 patient with an infection. Eleven patients (11 knees) had periprosthetic fractures at a mean of 11.4 (range 5-14) years after the index operation. The survival rate, with the end point being revision of the femoral or tibial component for any reason, was 98.7% at 10 years and 83.6% at 17 years. The survival rate of revision and periprosthetic fracture was 97.6% at 10 years and 76.9% at 17 years. Conclusion:Special attention should be paid to component loosening or periprosthetic fracture after more than 10 years of follow-up in this subgroup of patients. Contexte :On ne s'entend pas sur la nécessité de conserver ou d'exciser le ligament croisé postérieur dans les genoux rhumatoïdes en raison de l'affaiblissement du ligament, souvent présent chez cette catégorie de patients. Nous avons passé en revue sur plus de 15 ans les résultats de prothèses totales du genou (PTG) avec préservation du ligament croisé chez des patients atteints de polyarthrite rhumatoïde.Méthodes : Nous avons examiné les dossiers et les radiographies des patients pour évaluer l'amplitude de mouvement et les contractures en flexion des genoux, le descellement des composants et l'ostéolyse à l'interface os-ciment. Notre paramètre principal était la révision d'un composant fémoral ou tibial, peu importe la raison, et le paramètre secondaire était la révision, peu importe la raison, ainsi que les fractures périprothé-tiques durant la période de suivi.Résultats : Notre étude a regroupé 112 patients (7 hommes, 105 femmes; 176 genoux). L'âge moyen était de 49,3 ans (entre 33 et 64 ans). Vingt-et-un patients sont décédés et 16 ont été perdus au suivi, ce qui laissait 75 patients (119 genoux) et un suivi minimum de 15 ans (moyenne 16,1 ans) pour notre analyse. Parmi ces patients, 61 (101 genoux) étaient disponibles pour évaluation clinique et radiologique à la dernière évaluat...
