No influence of body mass index on early outcome following total hip arthroplasty

Abstract

We reviewed patients who had undergone total hip arthroplasties between January 2000 and October 2002 in order to determine whether a high body mass index (BMI) results in an increase in complications or re-operations. We compared 179 hip arthroplasties in 162 patients with an average BMI of 22.5 (18.6–24.9) with 164 hip arthroplasties in 151 age-matched patients with an average BMI of 33.3 (30–39.6). There was no difference in satisfaction between obese and non-obese patients following arthroplasty using a self-administered validated questionnaire (obese =  91%, non-obese = 93%, p=0.84). At a minimum of one year follow up, there was no statistically significant difference in the rates of complication (obese = 8.7%, non-obese = 7.6%, p=0.76) or revision surgery (obese = 3.6%, non-obese = 3.2%, p=0.85). In the short term a BMI >30 plays no role in an increase in complications or re-operation.

Résumé

Nous avons revus des malades qui avaient subi une arthroplastie totale de la hanche entre janvier 2000 et octobre 2002 pour déterminer si un index de masse corporelle (BMI) élevé s’accompagnait d’une augmentation des complications ou des réinterventions. Nous avons comparé 179 arthroplasties de la hanche chez 162 malades avec un BMI moyen de 22,5 (18,6–24,9) avec 164 arthroplasties de la hanche chez 151 patients d’âge équivalent avec un BMI moyen de 33,3 (30–39,6). Il n’y avait aucune différence dans la satisfaction après l’arthroplastie entre obèses et non obèses en utilisant un questionnaire validé auto-administré (obèse = 91%, non obèse = 93%, p=0.84). À un minimum d’une année de suivi, il n’y avait aucune différence dans les taux de complication (obèse = 8,7%, non obèse = 7,6%, p=0,76) ou de chirurgie de révision (obèse = 3,6%, non obèse = 3,2%, p=0,85). Dans le court terme un BMI >30 n’a pas d’importance dans la fréquence des complications ou des réinterventions.
