Original Paper


The prevalence of osteoarthritis is high in all ethnic and demographic groups. The timing of surgery is important because poor preoperative functional status is related to poor postoperative function. The aim of our study was to compare the preoperative knee function in patients of Asian origin with that of Caucasians living in the same community. We carried out a prospective study of 63 consecutive Asian patients and 63 age- and gender-matched Caucasian patients undergoing total knee arthroplasty. Preoperative Knee Society Clinical Rating System scores were recorded as a separate knee score and knee function score. The mean preoperative knee score in Asian patients was 37.6 compared with 41.5 in Caucasians (p<0.12); this difference was not statistically significant. The mean preoperative knee function score in Asian patients was 32.5 compared with 45.0 in Caucasians (p<0.00015); this difference was highly statistically significant. We conclude that patients of Asian origin undergoing total knee arthroplasty have lower preoperative knee function than Caucasians do. Cultural beliefs and social support partially explain this discrepancy, but health care providers must attempt to educate patients and close family members about the importance of timing the surgery to obtain the optimum benefits of pain relief and function.


La prévalence de l’arthrose est importante dans tous les groupes ethniques et démographiques. L’indication opératoire est importante en relation avec une dégradation de la fonction pré-opératoire. Le but de cette étude est de comparer la fonction pré-opératoire genou chez des patients d’origine asiatique et caucasienne vivant dans la même communauté. Nous avons conduit une étude prospective chez 63 patients asiatiques et 63 patients caucasiens en appareillant le sexe et ayant bénéficié d’une prothèse totale du genou. Le score de la Knee Society a été utilisé avec le score genou et le score fonction. Le score pré-opératoire moyen genou pour les patients asiatiques était de 37,6, comparé au score chez les patients caucasiens 41,5 (p<0,12), la différence n’est pas statistiquement significative. Le score moyen pré-opératoire fonction chez les patients asiatiques était de 32,5 comparé à celui des patients caucasiens 45,0 (p<0,00015), cette différence est hautement significative. On peut conclure que les patients d’origine asiatique devant bénéficier d’une prothèse totale du genou ont une fonction du genou inférieure aux patients caucasiens. Les aspects culturels et sociaux expliquent cette différence de même que les aspects éducatifs et permettent de décider de l’intervention chirurgicale de façon à obtenir le maximum de bénéfice de cette intervention et le meilleur résultat sur la douleur et la fonction.
